Minty Fresh: 1984 Yamaha RZ350

The RZ350 is a special sort of machine in the annals of RSBFS. The last of the 50-state factory two strokes, the little parallel twin that could utilized liquid cooling, a computer controlled adjustable exhaust port (YPVS), and catalytic converters. Even with all of this tech it was short lived on US shores, and even shorter for California. And while the RZ350 was made in decent numbers for delivery around the world (including the RD350LC variants sent to Canada), these remain relatively hard to come by in the US today. If you do find one, it is often modified, beat up, and abusted. And pricey. Today’s find is as clean and example as you are likely to hope for – with all stock parts in place and mileage that is actually reasonable. But better bring your wallet to this gunfight; the bidding is hot and heavy with only a few days remaining. The seller has included a LOT of detail, and I will let him tell the story of this special bike.

1984 Yamaha RZ350 for sale on eBay

From the seller:
This is one of the best original Kenny Roberts version RZ350s left in the world. I have decided to sell my collection of mint, original classic bikes. All my bikes were regularly ridden locally when we lived in California, but at 62, and since moving to MN last fall, I decided it’s time to downsize. I sold my KZ1000 MkII, CBX, RD350, RD400, Z1B, T150V Trident and CB1100F, leaving only this bike and my early Z1 which is the only one I will keep. The RZ is the last to be sold because I have been waiting for the MN title to come back (now in hand).

This is a 1984 Yamaha RZ350L (model 48H). Serial number is 000173: this is the 73rd out of the 9900 RZ350s to have been produced in 1984 (the first 100 bikes of each model that Yamaha makes are reserved for press/production prototypes). It may well be the lowest serial number RZ still in existence. The US RZ350 was only produced in 84 and 85, before US legislation made it too difficult to meet environmental regulations.

More from the seller:
The odo is showing 69xx miles (I am riding it a little), and the bike looks and feels like it is genuine. It was previously owned by well known classic RD parts supplier HVC Cycle (Lincoln, NE). Then the previous owner bought it from HVC and owned it for about 6 years. I have owned the bike 3 years. I only buy bikes with excellent original paint on the bodywork and frame. They hold their value much better due to the rarity. The fairing wasn’t perfect enough for me, so I found a NOS fairing (in Alaska) and NOS decals (cost $1200). The tank is perfect inside. Only the barrels have been painted (the original paint always flakes off). The original 48H pipes have been ceramic coated and came out beautifully. The small emissions pipes on the headers (not now used) have been capped with high temp silicone caps. No marks or dings on the bodywork except for a pea sized, very shallow dent (paint not broken) at the neck of the tank that can’t be seen. A tiny mark next to the Yamaha decal on the front of the fairing (see pics)

More from the seller:
The only mods made are not readily visible: emissions pipework and canister removed (I dont have it). Airbox replaced with K and N filter and Y Boot for better breathing. Dynojet needle kit fitted. Main jets increased to 420 (240 is stock which shows how much the Y boot improves the breathing). The 48H features the same barrels (same porting) as the higher power Euro 31K version but the stock US airbox and jetting restricts the engine to 52bhp. This bike probably makes more than the 59BHP of the 31K model due to better breathing. Diaphragm fuel tap replaced with conventional type. Carbs have been ultrasonic cleaned and set up by me. New float valves and jets. Fueling is perfect with no flat spots or hesitation. Starts and idles perfectly. Plug color is great.

I fitted new plugs, gearbox oil and EBC brake pads. I checked the oil pump. Motobatt sealed battery. New brake fluid and fork oil. I was told that Racetech cartridge emulators have been fitted but I have not inspected to confirm, however the front end feels very good and not undersprung for my weight (200lb). Compared to an RD400, these feel like a much bigger and more solid bike. Bridgestone BT45 tires.

The rare single seat is fitted (these were an optional extra). Also included is the stock double seat tail (also original paint) and grab rail. Both tails use the same seat. Buyer pays for shipment of tail. Also included user handbook, Yamaha shop manual plus complete original toolkit.

Many hi res photos can be found here: https://flic.kr/s/aHsmFQSxYk

Also you will see some of my other bikes (now sold) to give you an idea of the quality of bikes I have collected. Also see pics of the packaging that the NOS fairing came in (note original warning decal on screen).

More from the seller:
This bike truly looks and rides like a new bike. if you have been looking for an RZ350 for a collection, yet is still great to ride, this is it.

Clean title with current MN registration in my name. The bike is located just outside Minneapolis, MN. I can assist with loading if the buyer uses a shipper. I can keep the bike here for a month in my temperature controlled garage to help international buyers (two of the last four bikes I sold went to the UK). Bidders with less than 10 feedback please contact me before bidding, or the bid may be rejected.

On Aug-20-19 at 19:15:52 PDT, seller added the following information:
Note I have the Instavin report for this bike which shows it was originally sold in VA in 1984. The original owner sold it to Nebraska in 07 where HVC Cycle bought it and sold to previous owner in IL in 2012. I bought it in 2016. Serious bidders can get a copy from me at don_pottter at me.com

On Aug-21-19 at 07:40:04 PDT, seller added the following information:
A bidder had asked about the slight heat deformation on the lower cowl right side (the hi res pics I posted on Flickr allow you to zoom in on every part of the bike – please check them). I had forgotten about this since its not visible unless you look under the bike. When I bought the bike it had HVC pipes on it which are bigger diameter than stock pipes (HVC owned this bike). The cowl had gotten hot on one side. I put some aluminum foil to protect it. It has not gotten any worse because I replaced the pipes with stock which are much smaller. I took off the cowl and took pics, also of the underside while it was off – see the link to Flickr. As you can see its very clean under there. I also added a pic of the shop manual and the mint condition owners manual. I am 100% transparent with any issues. If you need more pics let me know.

With over 30 bids and over $9k, this bike has not yet reached reserve. When you think about it, $9k for a clean and original RZ is not much dosh. We have seen rattier and hacked up examples asking much, much more. I suspect that this one will spike near the end, but it all will come down to how high the reserve has been set. This seller has done a pretty good job of outlining the bike and how it came to be in this condition, including some of the restoration efforts necessary. Parts are getting harder and harder to find for these bikes, so if you are intent in owning a showroom example of the breed, you best start out with a complete one. This one fits the bill nicely. Drool over the many pictures, watch the video, and then check it out here. There is not a lot of time left, but plenty of action remaining – even if you’re just watching from the sidelines. Good Luck!!

Featured Listing: 2Moto 2M400R-SP

If you are thinking that you haven’t heard of the 2Moto 2M400R-SP, you are probably correct. But I’m sure you have heard of Yamaha’s wildly successful two-stroke, the TZR-250. And knowing RSBFS readers, you probably wished for something like that – but with more horsepower – for your street ride. I mean, imagine the wild hi-jinks you could pull off with that kind of hardware but twice the power. Well, wish no longer. Think of the 2M400R-SP as a top spec TZR, but with 400cc and 85 horsepower at the rear wheel. At 265 pounds, this hybrid weighs less than the 250 it is based off of, but is considerably more potent. At the end of the day this is less TZR-250, and more like what Yamaha could have done with the RZ350 had that lineup continued. We don’t often feature custom builds on these pages, but read on – because this one is worth it.

2Moto 2M400R-SP2004 for sale!

UK-based 2Moto is a bike builder that concentrates on just a few offerings. Most of their business is in the form of YZR500 and NSR500 GP500 replica race bikes. By tame comparison, the 2M400R is their street model – and what model it is! Start with 1990 TZR-250 chassis – this is the 3MA model offering, selected because it best fits the venerable parallel twin RZ motor. It is also widely known as precise and forgiving in terms of handling. Graft onto that a single-sided swing arm from the Honda RVF-400. The RZ style motor is a good choice as there is a solid foundation of knowledge and parts available; after all, these are the same basic engines utilized in off road quads. The power requirements of a quad screaming up a dune is quite a bit different than a racer / street bike, but by careful component selection, porting and assembly, a seriously stout smoker is born. Consider the dry clutch, the electric water pump and the clever custom carbon fiber sprocket cover that incorporates support for the gear selector shaft. Front forks are 600cc Supersport items, if that gives you any indication of the braking and cornering forces expected. Wrap that whole package in 125cc GP bodywork (yes, you heard that right – 125cc), and you end up with the spiritual successor to the RZ, and a phenomenal machine in its own right. This is a level of detail you would expect from larger firms such as Bimota, and the outcome is glorious.

From the seller:
Since the Aprilia RS-250, no new 2-stroke bikes have been built by any manufacturers. We thought it was about time to rectify that situation. And we like the RD-350 YPVS engine as there are lots of relatively inexpensive engine upgrade option courtesy of our American cousins who insist on racing some crazy Yamaha Banshee quads, some making in excess of 150 horsepower!

Having built plenty of specials over the years, we had a pretty good idea what would work. And, what doesn’t. The YPVS engine is fairly long, so most of the 250cc type V-twin chassis are too short, as we know from experience. In the end, the Yamaha TZR-250 3MA chassis fit the bill perfectly. Plus, the same chassis is used in the TZR-125 and the SZR-660, so availability is reasonable. And, we knew the engine would fit with only a few modifications to the chassis.

This highly desirable example of a modern 2-stroke sportsbike can be ridden on the street. A few of main specs are:
-400cc YPVS engine
-85 hp at the rear wheel
-120kg wet weight, no fuel
-K-Tech suspension
-The bike is titled as a TZR-250, 1990 model year and fully road legal in the UK.

Price: $12,500

Interested buyers should contact Felix Hirzel of Team 2Moto: info@2moto.co.uk
Website: http://www.2moto.co.uk

This custom build is not a simple one-off by someone in their backyard. This is a complete bike offered by a noted chassis and speed parts manufacturer. This is a repeatable process thanks to engineering, testing and experience. This is, as the ads say, professional grade. And if this 400cc doesn’t light your fire, perhaps you should check out their other offerings such as GP replicas of either the YZR500 or NSR500, race-ready Moto2 chassis, or a 250-sized GP racer stuffed full of Kawasaki 650cc twin power. Like Bimota, frame kits are on offer as well in the event you want to build your own. But what could be better than a professionally crafted, street-going two stroke like this 2M400R-SP? It is ready to go, no assembly required. Serious parties can send an inquiry directly to 2Moto’s Felix Hirzel, and talk numbers. Drool over the pictures on this one. Take your time. This bike has details you don’t want to miss. And if you miss riding a serious two stroke on the road, consult with your wife, consult with your banker, and consult with your local laws. Then make the call and make us all jealous. Good luck!!

Featured Listing: One-owner 1984 Yamaha RZ350

Update 8.5.2019: This bike has SOLD to an RSBFS reader. Congratulations to buyer and seller! -dc

This 1984 Yamaha RZ350 wears the iconic black and yellow Kenny Roberts livery and signatures, is original aside from some airbox mods and jetting and is with its original owner. It has 15,000 miles on it, but has been used very sparing over the last few decades, and it wears only its second front tire. The rear is similar, though somewhat unsurprisingly it has had three rear tires.

Built as emissions were about to kill street two strokes in this country, the RZ350 wasn’t as simple as its earlier counterparts, with powervalves to ease the two-stroke hit and catalytic converters to calm the EPA, but it was still a deadly simple and effective package. With just 331 pounds pushed around by 50-ish horsepower and roadracer handling, there was little not to like about the bumble-bee liveried machines. Sure, there were simpler ways to go fast, but there’s a certain joy to unrefined fast.

I’m going to let the seller do most of the talking, but this bike is a fantastic example of the breed, and is worth every red cent to the right person. He certainly has come to the right place to find the next steward of this wonderful beast.

From the seller:

1984 RZ350, Kenny Roberts Edition. Original owner, 15K miles. 99% original. You won’t find many in this condition. Still has the stock exhaust with catalytic converters. Last registered in 2011. Always stored inside & under cover. Colorado motorcycle so never exposed to moisture & humidity. Have the original sales paperwork, manual and tool kit. I was the service manager at the shop I bought it from. Outside of an 82 YZ490 hold over I bought at the same time, this was the only new motorcycle I ever had. The 490 was just a cheap dirt bike but this was something special.

Only modifications I made was to remove the snorkel from the airbox and drill some holes in the top of the airbox cover, add Boyesen reeds (have the snorkel and stock reeds) and rejet.

It’s on the second front tire (which would need replaced if you’re going to ride it as it has come cracking) and the third rear tire. The second rear tire I put on was a take-off from my road race bike in the late 80’s. Unfortunately it rubbed on the chain guard, so I notched it to clear. In hindsight I wish I hadn’t done that but you can only tell if you look closely at the backside of the guard. Replace the chain guard and top cover of the filter box and it’s 100% original out side of tires, chain and battery.

Original spark plugs and grips. All hoses and rubber are original and in good shape. Paint and plastic are in good condition and still shine. Has some minor scuffs and scratches as would be expected for a rider. Worst is the scratch on the LH side of the fairing and crack at the top of the fairing on same side (from vibration).

To get this in riding condition and ready for selling, the following was done: New battery and chain. Flush out the tank – clean, just a few very minor spots of surface rust near top, Clean carbs: amazingly clean for not being ridden for almost 10 years – only minor varnish in the bottom of one which cleaned up easily. Changed oil and coolant. Clean & oil air filter – which is also original and still in good condition; not falling apart. There was evidence of mice putting some seeds up there but that is all. Changed brake fluid – rear reservoir was very clean. The front one was very dirty and had considerable moisture/crud in it. Sight window is cloudy and shows it age.

Everything works. Runs and rides well – you wouldn’t know this is a 35 year old, non-restored motorcycle. Of course despite it’s great condition, it’s still bought as is.

$8000

The asking price is absolutely in line with the provenance and condition of this machine. We’re not dealing with a Craigslist crapshoot here, and the ask reflects that.

Two Picture Tuesday: 1984 Yamaha RZ350

Here is a beloved model smoker that was actually available to riders in all 50 States – for a brief period of time. The last of the true factory two strokes, the Yamaha RZ was 350 cubic centimeters of power-valved, parallel-twin goodness. Competing against the contemporary likes of the GPz550, GS550E and FJ600, the little RZ held its own as it buzzed its way into the hearts and minds of American youth. Today these 35 year old motorcycles are collector items, and highly sought after. Prices have been holding strong – if not climbing slowly – and time, butchers and accidents make the dwindling supply even more scarce. This advert has a fair amount of text but only two scant pics of this red/white beauty:

This US-based chainsaw shows nearly 15,000 miles on the odometer, and has been the recipient of numerous modifications and maintenance. There does appear to be some rash on the right side can, but hard to tell if that was a parking issue or a serious off. Back in 1984 the RZ350 was good for about 40-ish HP and retailed for $2,399. Today, this hot-rodded RZ is good for significantly more HP, and the price hike is nearly commensurate: the Buy It Now price is $8,000, or best offer. This is, unfortunately, pretty much in line with pricing for these models lately. We have seen higher dollar amounts for more original / lower mileage examples, but as a whole these models are getting harder to find and more expensive when you do. Check it out here. Serious tire kickers will want to request additional photos and details (or better yet, see it in person). Good Luck!!

Not Museum (but could be?): 1985 Yamaha RZ350

If you are a regular reader of RSBFS (if not, sign up for our email service so you never miss out on a great find), you will know two things: Number one, the RZ350 is a very popular model of semi-rarity her in the United States; and number two, sellers have been classifying “reasonably good” bikes as Museum Quality since the beginning of eBay. That leads to many examples of collectible motorcycles being represented as perhaps slightly better than they are. Even so, we revel in finding the rare and the unusual and try to bring it to your screen with an open view as to what it is and what it is worth. As such, we find this second red/white RZ350 in a week (see the first one here), and are all too happy to share what looks like an original example of the breed.

1985 Yamaha RZ350 for sale on eBay

From a collector standpoint, originality counts. And on an RZ, while aftermarket expansion chambers are period correct and aid in addressing two major exhaust faults of the bike (namely weight and performance), they are not original. Original means the basic black – but very trick – two stroke exhaust that incorporate catalytic converters and air injection to ensure as clean a burn as possible. Mr. EPA required said trickery in order to make the RZ an officially imported bike back in 1984 when the model was first brought to our shores. So effective were those cats that the small-but-mighty RZ even made it into California for one year! Today these are very difficult to find, and very expensive to replace. But they make the bike original. Original may not be the fastest configuration, but it is the best bet to earn every dollar possible on the resale of a classic motorcycle. Although not super-rare in the world, the RZ is most certainly a classic sport bike when it comes to American riders. So when you find a classic model in original condition, you have something special.

From the seller:
I HAVE HAD THIS BEAUTY IN MY COLLECTION FOR A FEW YEARS NOW AND TIME FOR A NEW PROJECT. IT’S BEEN A GREAT BIKE THAT IS USED REGULARLY AND IS RUNNING EXCELLENT. THIS IS A FINE EXAMPLE OF THE KENNY ROBERTS SPECIAL THAT IS IN VERY NICE UNRESTORED CONDITION RIGHT DOWN TO THE CATALYST CHAMBERS WITH WORKING ALARM.

THE ORIGINAL PAINT AND TANK IS NEAR PERFECT. NO DENTS OR RUST, TANK LOOKS NOS. CARBS HAVE BEEN RECENTLY SONIC CLEANED AND SET. ALL NEW OIL AND FUEL LINES INSTALLED, BRAKES, AND OIL INJECTION TANK FLUSHED. ENGINE IS ORIGINAL NUMBERS MATCHING WITH NO LEAKS. NEW FORK SEALS INCLUDED BUT NEED TO BE INSTALLED….THEY ARE LEAKING A BIT. TIRES ARE A BIT OLD BUT HAVE LOTS OF TREAD AND NO CRACKS. IT LOOKS LIKE THE FRONT COWL MAY HAVE BEEN RESTORED AT SOME POINT BUT I’M NOT SURE.

IF YOU HAVE ANY QUESTIONS OR WANT MORE PICTURES PLEASE DON’T HESITATE TO CONTACT ME. PLEASE VIEW THE PICTURES CLOSELY AS THEY SHALL GIVE YOU A LOT MORE INFORMATION THAN WORDS CAN. I WILL HELP WITH INTERNATIONAL SHIPPING IF NEEDED AT THE NEW OWNERS EXPENSE. DON’T LET THIS ONE GET AWAY YOU WON’T BE DISAPPOINTED!!

BIKE IS IN CANADA, NIAGARA FALLS AREA.

The seller has done a good job describing this particular bike, and provided the video to boot. As a 1985 model, King Kenny’s signature adorns the fairing (it was only on the yellow/black models in ’84), and said fairing looks good. So does the tank. The aforementioned boat anchor cats are well and truly in place (and operational, according to the over-temp alarm comment), although they *might* have been resprayed by the look of the finish. Of course time and heat cycles might have done that just as easily. There is some evidence of use and wear on the bike, but then again it does have 12,000 miles and change. Corrosion is not the dominant color scheme, which is always a good thing. Overall, this is a solid bike by my eye.

So this is what it comes down to: a rather well kept, reasonably presented, original bike with some of the faults and foibles you would expect from a used bike. And unlike our previously posted RZ, this one comes with a more realistic price tag: $8,995 if you buy it right now. Like the previous post, this seller is also open to offers. The days of the $2,500 RZ are long gone. The days when you thought $7,500 was a stupid-high number for a used bike are also seemingly gone. The RZ350 is popular; it was widespread enough to have parts availability, and it is unlike nearly any other machine offered then or since. There is something about it that tugs at heart strings, even though we know it is not the rarest or the fastest. But regardless of what tugs at your desires, do your homework and find the best possible example before you pull the trigger. Check out this clean example here, and see if you can’t snag yourself a little Christmas present before the end of the year. Thumbs Up & Good Luck!!

Red, White and Blue (smoke): 1984 Yamaha RZ350

The RZ market is pretty crazy right now. RSBFS staffers have seen bikes of all types of condition with pricing all over the map. We’ve seen bargains, we’ve seen riders and we’ve seen basket cases. We’ve come across amazing time capsules of authenticity, and seen the results of ambitious projects (sometimes gone bad). The bottom line is that the lowly RZ350 is as close to a sure thing as you are going to get in the current market. Regardless of condition, we are seeing these bikes sell. That must be pretty exciting for RZ owners out there. And for those in the market for the last of the street legal factory smokers, the good news is that we continue to see a good supply of the model. Which brings us to today’s example: a low mileage, red and white example of the breed that seems to have survived the ravages of time and riders.

1984 Yamaha RZ350 for sale on eBay

For those of you who missed the heyday of the two stroke, pull up a chair. You see children, back before people realized that they liked to breathe and came to the realization that vehicles spewing out noxious smoke, visible gasses and other delicious cancer-causing fumes were not a great long-term health plan, pretty much anything could be put on the road. And like any other performance category, sport motorcycles were all about low weight and high power. And pound for pound, a two stroke is a far more potent form of motive power than a heavier, more complicated four stroke. Sure, they sounded like chainsaws. Yes, they often disappeared in clouds of blue smoke. Indeed, they were a pain in the butt at the gas pump – not only did they get crappy gas mileage, riders had to mix oil into the gas in a precise ratio. But the payoffs were (almost) worth it when the tach swung up past 7,500 RPM or so and the power band began. Below that there was nothing, and with only a narrow RPM range of usable power, these were not the easiest mounts to ride in anger. The EPA started cracking down in the 1970s, and by the early 1980s the smoking party was over. But it was damn fun while it lasted.

From the seller:
Up for sale is a 1984 Yamaha RZ350. This bike is in Museum quality condition. Paint on entire bike is original and in like new condition. This bike comes with the dual seat option. exhaust resinators where removed at some point. If you are looking at this bike then I’m sure you aware of its heritage and the somewhat rareness of it. There are only 2 minor flaws, 1- the windscreen has a sratch on the painted area. 2- The tank has one dent on the left side.

The RZ350 is the little bike that could. Pitted against 550 and 600 cc four stroke machines, the little screamer could hold its own. But to even get it on the road, Yamaha had to throw a lot of technology into the form factor. An exhaust power valve automatically adjusted the exhaust port height depending upon specific conditions, making the parallel twin more efficient. Evaporation canisters to capture fuel vapors were starting to appear, and exist on the RZ. But the real secrets were hidden in the exhaust pipes. What looked like two stroke chambers were really a complex series of catalytic converters with air injection. These made it possible to import the RZ into nearly all 50 states for it’s limited run of 2 years (CA only received 1985 model year bikes).

This particular RZ has very few miles on it for the age (4,028). It looks to be in decent condition, although it may not have been an indoor pet all of it’s life given some of the light corrosion. The seller points out the relatively small flaws of windscreen scratch and tank blemish, but otherwise all parts appear to be attached. The pipes are not the stock units, and there appear to be some other small aftermarket additions over time (fuel line and filter, for example). The term “museum” is an ambiguous word that comes up all too often in adverts. Calling this example out as museum quality depends upon the type of museum you frequent. This is not a zero mile, just been un-crated, never been run, never been rode or never been parked outside type of bike. This is certainly a low mileage survivor, and for those that want to ride, this is usually the better option. The seller is asking for some pretty strong numbers for this bike – but the market will pay what the market can bear. You can’t fault someone for asking, and the Buy It Now approach with a willingness to accept offers might just be a great way for the seller and buyer to meet closer to the middle. Check it out here – there is not a lot of text but a good number of decent pictures. And then you just have to answer one more question: Do you RZ? Good Luck!!

Buzz Buzz Buzz: 1984 Yamaha RZ 350

The last street-legal production two stroke sport bike officially imported into all 50 States of the US by a major manufacturer, the RZ350 holds a special place in the heart of motorcycle enthusiasts. It was Yamaha’s valiant move to bravely keep the two stroke spirit alive and kicking in the face of tightening emission and noise regulations. It was both a brilliant success and an ultimate failure; a short lived lifespan that stirred hearts as technology passed it by. Enthusiasts who reside outside of the US may wonder at the American fascination with this bike – after all it had been in-market outside of the US for years and would certainly not be considered rare. But unlike grey market imports, this was one model that we could truly call our own. And with bold Yamaha bumble bee graphics and American superstar Kenny Roberts signing the fairing of every one, this one was ours. The RZ350, for all its shortcomings, is a legend.

1984 Yamaha RZ 350 for sale on eBay

If you look at the bloodline, you can see the DNA that evokes the Yamaha RD models that came before. But designed as a modern approach to the “less is more” philosophy, the RZ added liquid cooling to the familiar parallel twin. The two-stroke powerband was (partially) tamed by the introduction of computer controlled power valves, varying the exhaust port height depending upon RPM and throttle settings. Oil injection was standard, eliminating messy mix ratio cups and associated refueling hassles. And there was a secret weapon: hidden in the smart looking exhaust pipes were a complex set of catalytic converters, just like you would find on your car. With the cats (and some air injection), the RZ could sneak into all 50 States of the Union, including the super-picky EPA stronghold of California. Sure, the cans were heavy, they were expensive to replace (i.e. crash damage) and they did not perform nearly as well as expansion chambers and stingers, but they made the bike possible in the US. They were also easily replaced, which is what most everybody did. Immediately.

The RZ350 was intended to compete with the current crop of middleweights; likes of the Kawasaki GPz550, the Suzuki GS550, or even Yamaha’s own Seca 550 and FJ600. In that space, the stock RZ was outgunned by the bigger four cylinder four strokes. But the little RZ had agility on its side, and once on the pipe could fare well. But it would never be a great all-’rounder, given the peaky nature of popcorn power. There were many aftermarket and tuner tricks to unleash the beast. Typical tricks of overbores, decking the head to increase compression, and porting were effective. The fact that the Banshee, a Yamaha ATV, utilized the same motor definitely helped with parts availability and knowledge base. But despite the potential, the little RZ was not to be long lived. After a scant two years (and only one in CA), the RZ was pulled from the dealer floors. The party was over, and the used party began. This is where we pick up the story on this bike.

From the seller:
Bought this bike in 2001. Have ridden this bike regularly for 17yrs. Always kept inside. Rebuilt engine because of mileage. I am over 60 yrs old AMI certified motorcycle mechanic for 41yrs. and ride like a grandpa and take care of my things the same way.

– Work Performance rear shock
– Engine Rebuilt 1500 miles ago
– .020 Pro-X pistons,windows cut to match intake
– TDR reeds
– stage 1 porting
– Toomey pipes
– stage 1 dyno jet kit w/2into 1 K&N air filter
– Wiseco Hot Rods crankshaft
– New clutch w/springs
– Full gasket and seal kit
– Race Tech front fork springs
– Chain and sprockets 1500 miles
– New seat cover and battery
– HID headlight
– Powder coated frame
– Bike Dynos out at 59.6 RWH on Dayton Dyno at my shop!
– Spec II Full race fairing
– Fuel tank has no rust, has small quarter size dent and touch up on right front side

Forty Thousand Miles. Let that sink in. Most RZs don’t get to that point, having been thrashed, abused, modified, seized and crashed. This particular bike has an amazing number of miles, but looks great. It is clearly no museum collector given the mods, but from a period correct standpoint – hell, from a fun to ride standpoint – this one piqued my interest. The .20 overbore either means the engine had been refreshed once before, or perhaps it was necessary to go that deep due to scratches in the bore. Regardless, that means for bigger pistons and more power. The K&N filter and Toomey pipes are perfect add ons, as is the full Spec II fairing. This bike has been stripped and rebuilt, as evidenced by the powder coated frame. But that just means you are potentially getting a nearly new bike out of the deal.

If you can get past the mileage (40k!) and the non-standard mods, what you are looking at is a great rider. This is a bike that deserves action rather than parking in a museum – although I must admit it looks pretty good. And with a long term owner and a capable wrench (just an assumption, but how many owners out there have their own dyno??), this bike could well be good enough to fill the two-stroke void in your stable. The best part is the price: compared to 90% of what we see on RSBFS, this chainsaw is a veritable bargain. The opening ask started at a reasonable $3k, and bids are flying fast and furious. The Buy It Now price is a mere $4,500, meaning that this bike will likely sell before the auction is over. Check it out here, but better be quick about it. It might already be gone. Good Luck!!

Buzz Buzz Buzz: 1984 Yamaha RZ 350

Featured Listing: 1984 Yamaha RZ350 for Sale

Update 8.28.2018: This bike has SOLD! Congratulations to buyer and seller! -dc

Although two-stroke sportbike production continued well into the 1990s in much of the world, here in the US the Yamaha RZ350 was pretty much the end of the line. Blame stricter emissions laws and progressively bigger and faster four-strokes in a country with very liberal licensing laws and no taxes on bigger bikes. Today’s Featured Listing RZ350 has classic black-and-yellow King Kenny Roberts graphics and aftermarket Spec II bodywork that gives it a more modern look, compared to the bikini-faired original.

The aftermarket full-fairing does more than provide style and wind-protection: it moves the mounting points from the bars to the frame to improve stability as well. The solo tail in particular looks like something from the later Yamaha sportbikes. It suits the bike, although the big 18″ wheels and skinny tires give the bike’s age away. The RZ really did bridge the gap between the old and the new, coming as it did between bikes like the old-school RD-series and the later, more modern FZRs.

The bike was sold in the US from 1984-1985 and followed Yamaha’s famous RD-series, adding liquid-cooling and Yamaha’s game-changing YPVS powervalve system to the mix. The 347cc parallel-twin made 52 claimed horses and weighed in at a svelte 370lbs wet, making it loads of fun on a winding road, although the two-stroke power delivery requires commitment to extract, since it peaks at 9,000rpm, redlines at 9,500, and is pretty much dead below 6,000.

This example is in excellent condition with very minor cosmetic flaws well-documented by the seller in the pics below. The bodywork is obviously not original, but the bike has been thoroughly maintained and thoughtfully updated.

1984 Yamaha RZ350 2 Stroke 

VIN # 00854

Engine # 00854

This low serial number RZ350 was purchased in Southern California two years ago. It has been garaged in the area since that time. It has the original engine and transmission plus many upgrades.

Just over 8000 miles on original engine.

Recently completed was a mechanical restoration and engine top-end rebuild by renowned RZ Oracle Cary, owner of RZ’s Unlimited. I have all receipts for the work done which are available via email upon request.

The bike has just 200 miles since restoration and must be broken in. I have all instructions from RZ’s unlimited for you to break in the engine. Rest easy knowing that your RZ was broken in properly.

Everything works on the bike and it starts up right away. 

The bike runs like a dream.  

Videos:

This RZ has the Spec II full fairing, Spec II exhaust pipes, and one-piece seat/tail section, clip-ons and aftermarket rearsets.

Tail section was hand-painted by Gerod, owner of Valley Kustoms: that is not a decal.

There is a small quarter-sized dent in the right side of the tank as well as a few small touch-up paint spots. The right side pipes have 2 small dents / dings which are pictured. 

Great bike; ready to eat R1s all day long.

Prices seem to be all over the place for RZ350s a the moment, but decent examples are still pretty affordable. The aftermarket bodywork may turn off purists, but anyone looking for a very solid bike with some mild performance modifications should give it a careful look. This RZ350 is located in Los Angeles at Iconic Motorbikes and is the very definition of a practical classic: performance is good enough to keep up with modern bikes on the road, and parts are relatively easy to source if you want to use it regularly.
