Legend: 1985 Yamaha RZ 350

Every iconic bike tells a story. In the case of the RZ350 – the last of the factory imported two strokes into all 50 U.S. States – the story is one of evolution. The RZ (or RD350LC as it was called in other markets), was an evolutionary beast that began with the RD series of the early 1970s. But the RZ took the parallel twin two stroke concept much further, by adding liquid cooling and a trick exhaust port power valve to widen the power band (YPVS), not to mention the catalytic converters in the pipe trick. This particular bike has a story as well. And far from some adverts we see where the owner says (or knows) nothing about the bike in question, today’s seller has written a ton. I will let him pick up the story.

1985 Yamaha RZ 350 for sale on eBay

From the seller:
Step 1: The purchase
My desire for a top of the line RZ350 started years ago, but in early 2014 one came up for sale 800 miles from home. My wife and I jumped in my truck and arrived in Missoula MT to pouring rain and freezing temps. “perfect bike buying weather”. The seller was short on words, the bike was complete but the wheels were seized from sitting and the buyer all of a sudden “couldnt find the paperwork.” Are you kidding me? After we drove 3 states to come buy it? So i said I’m paying you 300 dollars under asking until you can find the title, long story short, he blocked me and I never heard from him.

More from the seller:
Step 2: Contract the builder
Reach out the best 2 stroke tuner/builder I know at the time. His name is Troy Gessner out of Bellingham, WA. If you’re ever curious, go look at 125GP records, his son John, had all of them. His dad is a 2 stroke genius and was a meticulous engineer type mechanic. Never cuts corners, never says “that should be ok”. While every other GP125 would have some sort of a mechanical or seizure, John and Troy went 2 years with 2 mechanicals, and both were electrical related, not catastrophic mechanicals. At any rate, I reach out and he says tell ya what… You get that RZ, and I’ll do a frame up, cases up build for you, at half what the shops would charge. Deal. He’s recently retired, and excited to work on a 2 stroke bigger than a 125GP Honda. We talk about the best route and without going into politics, WA state is real bugger on VIN/No title issues. So we result to buying a frame and title off of Ebay from AZ. Frame arrives to Bellingham, i take paperwork to DOL, we get title in my name, the DAY we recieve the proper title, clean title, Troy got to work. Please note, we are building a true Spec II Racing version of the RZ350. Spec II oem bodywork, Spec II windscreen, Spec II crankshaft rebuild and weld up, Spec II pipes. THIS IS A NON-MATCHING FRAME/ENGINE. Since this is a fun Spec II Yamaha version, the vin on the frame and the vin on the engine should absolutely not matter. It surely didnt to us. This is an aftermarket build with todays components and goodies almost everything upgraded to be better.

More from the seller:
Step 3: The build.
When I tell you that this was a nut and bolt restoration, I’m not saying it was “kinda taken down and slapped together with new top end and pistons” I”m talking every wear item, every nut bolt seal was ordered through Yamaha. We paid hundreds of dollars to have oem fasteners, nuts bolts springs, seals, all OEM. Here’s the short list. You will recieve with the bike, a build book. See final photo, its 1 page of your build book where Troy outlines every detail from every day he spent working/building the bike.
Entire bike disassembled down to nothing. Everything in the engine was in working order except the cylinder head showed some bad gas pre-detonation wear, so we waited for a month for a perfect OEM Cyl head to pop up on ebay.
Crankshaft sent to Spec II Racing to Gary for rebuild and welding.
After tearing everything down we realized after talking to the painter, the only way to get that specific decal kit to look right, is if its on the bike. Trevor Beckman at FlexiGlass in Vancouver Canada, needed the bike almost like it was going to be done. So the only way around this was to put the bike back together, without the engine and drive the entire bike to him across the border. Troy did just that. The Spec II edition decals were applied to the bike on top of the white paint but underneath the clearcoat, just like it should be. the paint/clear looks like a factory job. After paint was done, Troy went to pick it back up, and carefully disassemble it, and put the bodywork off to the side. Ducati red and bright white. Are those factory colors. Nope. Do they look correct, yup.

All holes in the frame were cleaned and die tapped. The frame recieved new head bearing races in the frame (and bearings upon reassembly)

More from the seller:
The internet says that the rear shock is “not repairable” Troy brought the rear shock to KFG Racing. You may have heard of them, they’re the #1 suspension shop on the westcoast. KFG drilled/tapped the shock, recharged it, and resprung for a 200lb rider. No more saggy bike with worn out 35 year old shock for a 140lb rider. Even better, when you buy the bike, if in 10 years it feels soft. KFG can service it again for you, like a current day sportbike shock. The front forks were torn down by Troy personally and rebuilt with new internals and oil. The calipers were nasty. He tore them down and rebuilt them with new parts and new brake pads. The wheels and calipers were in great shape. The bike only had 15k original miles.

When Troy reassembled the transmission, all the small washers, seals, springs, pins, bearings were replaced. Everything reassembled like a tech would in 1985. Shifts like a new bike.

Engine wise, the engine is stock. No crazy porting. No changes to compression. Troy says “we want this bike to last. We want it to run prime, and behave on the street.” So I agreed to that for sure. We decided to install VFORCE3 reed cages for some added mid-range power. Rebuilt oil and water pump. New bridgestone tires.

Things not restored: seat/seat cover, wheels, calipers, tachometer cluster, bar end mirrors kept.

Amsoil Dominator 2 stroke race oil injector used for break-in. Coolant topped off, Yamalube oil for trans. Bike runs like a dream, pulls hard, shifts hard, sounds great. Has a nice crackle to the pipes 🙂

More from the seller:
Lastly……Step 4: The negative. (small stuff!)
Ready for the bad news? (I told you. No surprises. Thats not how I sell)
Upon getting the bike back together, I went up to Troys house and he says well Darren the bike is back together go ride it. But we do have a ever so slight (a drip an hour) leak near the petcock. so we wipe the drip and go for a ride. Bike is great, I pay troy for his time, and i’m on my way home. I get home unload, go ride it again, I go for a 35ish mile ride, I’m as happy as a clam. All the electrical works, bike pulls, corners, shifts, and brakes, like a bike 20 years, 30 years newer! The gauge cluster still has a small chip out of the lower right side. very minor, see photo. I’m all smiles…. Until the next morning. I head out and the shop has a strong gas smell. I find a grapefruit sized puddle of fuel on the ground. I realize the tank leak is a bigger issue than I first realized. I touch the area up UNDER the bottom of the tank, if you know RZ350’s, they have a section of a half an inch that is LOWER than the petcock. A horrible design as all RZ owners know. I didnt catch it, Troy didnt catch it and VERY sadly, the painter/sander, did not catch it 🙁 Now we have fresh paint, fresh decals from australia, on a tank that needs some sort of a repair. I am no body guy, but i did what I could to try to fix it. i used an exacto knife on the fresh paint up under the tank maybe 1″? (i know, teeth gritting to read that) and I applied a thin line of JB weld. It was a temporary fix that worked for a few months, but it didnt fix it. I rode it 1 more time. I’ve had the bike entered in 2 motorcycle exhibition shows, and it one that gets the looks. And now the embarrassing part. A small dribble lead to the bike being parked and “i’ll deal with it later.” Its 2021. I opened Troy’s book to read off some of the meticulous notes, and it starts off with “15 May, 2014″….. I just shook my head. I have a family now, and I’ve decided to split ways with the bike. So you know the entire story. You’re getting the best of the best, frame up, engine up, suspension up type bike. You’re getting bodywork that is as rare as a white unicorn, a windscreen that is no longer in production, and pipes that are hard to find. BUT you will need to repair the slow leak gas tank. At this point you will need a new battery. The bike has approx 50 miles on it.

The long and short of it is that RZ350s are money these days. Non running junkers are going for what great riders were going for less than a decade ago. Today’s seller spent a lot of time (and money, undoubtedly) to build a very clean example of a neo-RZ – keeping to the original theme, but making some interesting and cool modifications. Clearly the Spec II parts and pieces approach works from a period-correct perspective. The pictures show a bike restored to a very high standard, but the tank leak is definitely unfortunate. So, too, is the damaged bezel given the overall condition of this machine. Which brings us to the asking price of $15k. That is big money, although a completely restored stocker might pull it off. The seller appears to be open to offers, so check out all of the details here and give it some thought. Good Luck!!

Out in the Yellow Paint – 1985 Yamaha RZ350

A classic in part because it’s the last year of U.S. imports, Yamaha’s Kenny Roberts edition typifies two-stroke fun.  Here’s a windy city example with low miles, excellent cosmetics, and Jim Lomas expansion chambers.

1985 Yamaha RZ350 for sale on eBay

Yamaha had their air-cooled 350 in the house since 1973, but liquid cooling brought more stable cylinder head temperatures and better all-round running to the RZ.  YPVS electrically tuned exhaust ports made for a wider torque band and 59 hp.  The RZ had Yamaha’s first perimeter frame on a road machine, in steel tubing with a racer’s drop-in fuel tank.  Other race-bred improvements like triple disk brakes and monoshock rear were making their way on to more popularly-priced bikes.  Yamaha’s day-glow GP race livery reflected their Marlboro sponsorship, but the AMA series speed block livery is adorned with Roberts’ autograph.

Apparently for sale by owner, this beauty shows just half of the 25K miles a lot of RZ’s have, with just a couple of paint chips to show for 36 years.  Throaty exhaust notes in the too short video posted – here –, and just a couple of comments from the eBay auction-

Kenny Robert’s edition, the most desirable year of the most desirable color combination Yamaha RZ 350. Very low original miles (12,647), clean title with owner of record since 1991 and matching VINs. Runs well, idles perfectly, fires up first kick and it was jetted for JL pipes.The bike is in overall in great rider quality condition, it has some very minor imperfections shown in the pictures below. The bike sits in my climate-controlled building and is available to view anytime.

Winning two Grand National Championships, and three World Championships ( and being runner-up in each once ), Roberts is a champions champion.  There have been other yellow and black comemmoratives since the RZ350 was legislated out of existence, but this is still number one.  For a fan of the man, the brand or the sport, a fresh-looking two stroke sportbike would be a great tribute to have in the garage.

Out of Towner – 1986 Yamaha RZ350

Since the RZ350 was sold here until 1986, it’s relatively rare to see the fully faired rest-of-world edition.  Though this example isn’t currently operational, it shouldn’t take much to bring it back to the living – not to mention California title !

1986 Yamaha RZ350 for sale on eBay

For 1986, the RZ350 used Yamaha’s 347cc parallel twin with their electrically controlled power valve, and revised porting and combustion chamber helped make 59 hp at 9,000 rpm.  The lightweight rode on 18-inch alloys with air-adjustable forks and monocross rear.  A perimeter chassis and swingarm were executed in steel tubing, with triple disk brakes.  The full fairing was new for 1985, but 1986 saw a revised tail fairing which perhaps looked sportier in its simplicity.

Not seeming to be a dealer, this owner invites inspection at their home.  The RZ shows very well, with 14,403 km’s or a hair under 9,000 miles.  Finishes and plating indicate inside storage.  Nicks and dings keep it from being a real show bike but once it’s back on the road, it would be a smashing rider or riding resto.  Comments from the eBay auction:

The bike is the full fairing Canadian model that was imported here in the US and it comes with a clean CA title and non-op registration.  The motorcycle is in excellent condition and has approximately 14K Kilometers which is equivalent to just under 9K miles. As shown in the photos, the bike is in excellent cosmetic condition with only minor blemishes to the paint as shown in the last photo. 

The bike has been stored and was drained of fluids, so it will need a light service to get running including but not limited to a new battery, fresh fluids, and possibly a carb cleaning.  The motor kicks over with great compression, the throttle turns, clutch and brakes are working, inside of gas tank is clean, electrical is working, etc. so it should not take very much to bring the bike back onto the road. 

For anyone considering this bike as a collectors item or investment, the bike is a numbers matching (Vin to Engine) vintage motorcycle in mostly all original factory condition, this bike has not been restored but rather it has been on display and preserved for most of its life.

Can’t pretend to understand the RD / RZ / LC confusion, but the actual bike has made more incremental changes over the years and across continental divides.  Meanwhile the two stroke Yamaha fun factor is un-parallelled.  Bidding seems serious in this auction, with more than three days yet to run.  The new owner will have a distinctive RZ350, and will get a chance to know it better during the re-commissioning.

Almost Famous: 1985 Yamaha RZ350

How much does star power help with motorsport sales? It helps if the figure connected with the sale is related to the vehicle in question. And in the case of the RZ350, the connection is very, very good. Sporting the signature of “King” Kenny Roberts, the RZ350 came emblazoned with the bumble bee livery that made Yamaha famous on the race track. As the last factory two stroke to be imported into all 50 US States, the RZ350 is held near and dear as a truly special bike from a bygone era.

1985 Yamaha RZ350 for sale on eBay

For those that have been living in a cave without AOL dial-up, let’s go over the basics: Take the spiritual heart of a RD350/RD400 – namely the two stroke parallel twin – and throw go-fast technology at it in the form of liquid cooling and a computer-adjustable exhaust port that enhances the typically peaky two-stroke power curve (YPVS). For those that like to breathe, the RZ came with an exhaust system that incorporated catalytic converters and air injection to prevent mosquito fogging the street/canyon/track with bllue smoke where these bikes played. The rest of the gear was fairly conventional, including a mild-steel frame, a single shock rear suspension system and triple disk brakes.

From the seller:
1985 Yamaha RZ 350 Kenny Robert’s edition. The most desirable year of the most desirable color combination Yamaha RZ 350. Very low original 6809 miles. Runs well, idles perfectly, fires up first kick. Stock oil injection system remains intact. Stock carbs, rejeted for the Toomy pipes and 2 into 1 K&N air filter. It is stock bore with new high performance pistons. I pulled the top end just to inspect and check everything, replaced the pistons because I had an extra set.

This bike came from The American Pickers in LeClaire, Iowa and was on of their shows. It was purchased locally by a motorcycle collector, and I purchased it from them. I have the bill of sale from Iowa.

The bike is in over all in decent rider quality condition, it has the normal nicks and dings as it is a 35 year old motorcycle. This bike would be a great candidate for an easy restoration or enjoy as is.

Like most RZs, this particular example has shed it’s restrictive, heavy catalytic converters in favor of some old-school expansion chambers. That is one way to really wake up an RZ. The air filter mod – in conjunction with the exhaust swap – requires changes to jetting, since the motor is now able to flow more air. Racers usually disabled the oil injection system in favor of mixing oil right into the gas (again, old-school), but street riders will appreciate the ability to fill up the tank without the use of a mix-rite cup.

This particular bike was apparently featured on the TV show “American Pickers.” I’m not really sure if that adds any value, but does prove that many people think the RZ is cool. Pictures show a bike in pretty good condition. This is not a meticulously spotless museum piece by any means, but nor is it a thrashed, crashed and trashed example asking for an outrageous price. With no reserve and a single bid at time of writing, this RZ is in the $6,500 zone – which is close to where you might expect. There are a significant number of folks watching on, though, so you might see some last minute activity on this auction. Check out all of the details here, stay safe and good luck!!

Been There Done That – 1985 Yamaha RZ350 with Just 1,972 Miles !

Introduced in 1982 as the closest thing to a race bike on the road, and certainly one of the last two-stroke street bikes available here, Yamaha’s RZ350 can be found in all prices and conditions.  With its sights set on the top of the hill, this later Fla. example has impossibly low miles and almost flawless condition.

1985 Yamaha RZ350 for sale on eBay

The early -80’s brought the Yamaha Power Valve System to their two-strokes, and it helps the engine run just fine around town.  But the 55 rated horsepower are available up at 9,000 rpm, requiring a more advanced set of rider skills.  Racey looks are helped by the perimeter frame and drop-in fuel tank, just like real racers of the day.  Dual front disks were new on a lighter-weight machine, and compensate for the lack of engine deceleration on a smoker.  Suspension wasn’t fancy, just preload adjustable but good quality like the rest of the build, and the gold-trimmed alloys had a light look.

An expert might be required to find something to quibble about on this RZ, and you’d suspect an odometer rollback if not for the museum condition.  Factory pipes look sharp and dispense with the catalyzer.  Comments from the eBay  auction:

Kenny Roberts Edition purchased from original owner earlier this year. Great condition very little patina  two small little touched up chips one on tank and fairing smaller then pencil eraser in front of gas cap the blue stripe is starting to shrink I don’t know if its from gas or what but that’s the only complaint I have with the bike because the rest of it is killer front forks are clean with very minimal rash the rims and controls are in great shape and look awesome. I have original pipes and tool kit look at the pics they tell the story look at them well please ask any questions or more pic’s if needed and the bike runs great . Miles are 1975 and the bike is all original not restored and shows extremely well for a 35 year old bike that hasn’t been monkeyed with and adult owned and cared for.

Like real estate, they’re just not making any more RZ350’s, so this owner can wait until his whopping buy-it-now seems sensible or someone makes an offer.  Not sure this year is CARB legal even with the original exhaust, but a knowledgeable reader will likely sing out.  The alternate livery doesn’t scream Kenny Roberts like the yellow, but it’s there.  You can usually hear me groan about bikes destined for the carpet, but this one is really too nice for anything but an occasional spin around the block.

The Clean Side of Dirty: 1985 Yamaha RZ500

The legendary Yamaha RZ500 – the twin-crank, V-4, 500cc two stroke GP bike for the street – never officially came into the United States. By the late 1970s the EPA had their sooty little hands in, well, everything, and raucous power plants such as internal combustion two strokes were strictly off the list. Yamaha tried for a couple of years with the 500s baby brother, the RZ350, but ultimately shelved the clean air catalytic converter project. They didn’t even bother trying with the bad boy 500, and perhaps it was better that they didn’t. The RZ500 was a down and mean smoker, and never tried to apologize for that fact. It landed on the shores of North America and rolled on Canadian soil, but such was as close as it came for eager and lusting American riders. Thankfully many were unofficially imported into the US as used bikes, which brings us to this particular example.

1985 Yamaha RZ500 for sale on eBay

The seller of today’s bike has quite a bit to say, and I will let him pick up the tale from here:

From the seller:
Yamaha Other. 1985 Yamaha RZ500 2 stroke. Low miles. Speedo is in KM and bike has 5300 miles. I purchased this bike from the 2-stroke guru Rick Lance a few years ago before his passing. http://www.lancegamma.com He gave it a once over inspection and replaced the crank seals and gave it a tune up. Those who knew Rick can attest to his competence regarding two strokes and his integrity. He was aware of the history of this particular machine and stated he believed the engine had never been apart and was a great example of a stock, unmolested low mileage RZ500. I’ve seen numerous RZ500s over the years and have even raced them and this is one of the nicest, cleanest survivors. Upon receipt, I took it for a quick test ride to ensure everything was working properly. Lights, turn signals, horn, brake lights, etc. function as designed. The bike shifted through the gears and there were no mechanical issues. The bike even has the original tool kit and fuel tank service cable. The interior of the tank has no rust and the bike has new tires and battery. Because of the altitude of my location (4200 feet MSL),the bike did tend to bog and was in obvious need of a rejetting as it was running rich. After consulting with Rick, he said the bike had run clean at his altitude in North Carolina before shipping. Not having the time to work on it, I drained the float bowls and tank and put the machine into storage with the intent to rejet the carburetors and ride it in the future.

More from the seller:
Unfortunately due to work and personal commitments, I never did rejet and have decided to sell off several of my collector bikes. Not knowing where the machine would be shipped, I decided to leave the jetting for sea level instead of taking the time and effort to set it up for my altitude. Overall, this is a classic machine in great condition. It does not appear to have had any crash damage. Check out the YouTube link below of the bike running. It fires up on the first or second kick. Please feel free to ask any questions. When I sell on Ebay, I try to be as honest and forthcoming as possible. If you have a shipper, I’ll work with them on pickup or dropping the bike off at a location in the Salt Lake area. Please feel free to ask any questions. The bike has a clean Utah title. $500 non-refundable deposit required in 24 hours and full payment in 7 days. Bike is sold as is with no warranty although honestly, it’s in great shape and Rick Lance gave it a clean bill of health. The bike and title will not be released until payment clears. Thanks for looking.

If you doubt my earlier statement about “Ole Smokey” the 500cc two stroke, allow me to share the video created of this bike by the seller. I can practically smell the castor and revel in the sounds (and undoubtedly the lack of mosquitoes!).

This bike looks clean, clean, clean. The fact that it went through Lance Gamma’s shop is a real plus as few people knew and lived this era’s smokers like Lance. This bike has been wonderfully photographed, and shows its originality proudly. The miles are low, but I’m sure the riding smiles are off the charts! These big RZs are getting harder and harder to find in clean and original condition, and prices are definitely on the collector side of the fence these days. If you want one, the time to get in was yesterday – but better late than never. The current auction bid is up to $14k with reserve still in place. Check out all of the details here, and Good Luck!!

Winter Blues: 1984 Yamaha RZ350

As many parts of the United States are deep in the throes of falling frozen water, riding is an activity that must wait for warmer weather and more favorable road conditions. There are locales, however, where riding can commence year ’round. The southern states on both coasts serve as a great example. And it is from one of those states where we find this immaculate 1984 Yamaha RZ350, ready to ride. If you are snowed in and looking for that winter project that might require TLC and lots of mechanical know-how, stop reading now. This particular bike looks to need nothing but high RPMs and silly grins. If that is your idea of a winter project, read on!

The RZ350 is well known as the last of the factory 50-state street legal two strokes. Known as the RD350LC in other geographies, the RZ was the continued evolution of the parallel twin RD lineup, but with a healthy dose of modern tech thrown in. Sure the chassis was mild steel and not aluminum, but that did not stop the RZ from sharp handling. Brakes were triple disks, rear suspension was of the new-fangled single shock design, the venerable twin was now liquid cooled for tighter tolerances and greater power, there was a computer controlled bridge attached to the exhaust port to spread the notoriously peaky powerband around some, and the exhaust pipes were fitted with catalytic converters to help the dirty two-stroke meet EPA emissions. In most ways it was a toned down version of itself, but the beast within was woken up easily with a few common two-stroke tricks. The party only lasted two years, but it remains a very memorable party indeed.

From the seller:
1984 YAMAHA RZ350. Bike has less than 500 miles on a total renovation. Stripped to frame, wheels, bodywork all painted. Original exhausts go with the bike. Brand new Original CDI Spare also goes with the bike. The bike does not need anything. I never ride it anymore to many other things going on. Clear title, the bike is in ORMOND BEACH FL.

I have a reasonable reserve for this bike in this condition. Please do not message with silly offers. The bike sits in my climate controlled building and is available to view anytime. Everything works as you would expect. The gas cap area has been treated with an epoxy to resist any gas overflow from affecting the paint in the silly recess around the gas cap. (yes I have overfilled it) Not much more I can say. If you are looking for an RZ that requires nothing but a rider then you know what you are looking at.

There is a fair bit of interest in this particular RZ, and the eBay auction has a good number of followers. Bidding history shows the relatively quick escalation from $2k to the current bid of $7,400 – but we can be pretty certain it won’t stop there. The seller indicated that there was a reasonable reserve set for the bike, and that is clearly the case; the reserve has already been met. Whatever happens from this point forward, this bike is going home with somebody. Check it out here and let us know if this isn’t the cleanest RZ you have seen in quite some time. It has some aftermarket expansion chambers (great for waking up the beast) and the seller will even throw in the original pipes with the deal – which is great for someone looking for an original collector. The RZ is a constantly sought-after machine, and we anticipate prices to continue to rise. If you are in the market, best jump in while prices remain somewhat sane. Good Luck!!

Ringer: 1984 Yamaha RZ350

I know that the RSBFS reader loves a good two stroke. And what better to post than a well-kept Yamaha RZ350? The last of the true factory street bike smokers, the RZ was successfully imported into the US – and even California! – for a short while. And so while these are not grey bikes snuck across the border from elsewhere, they are legitimately rare and loved for what they are. And unlike a nearly $20k Gamma or RZ500, the 350 is something that mere mortals can afford, and live with on a daily basis.

1984 Yamaha RZ350 for sale on eBay

The reed-valve parallel twin that powers the RZ350 is a spiritual successor to the air cooled units on the earlier RD series. Bristling with 1980s technology such as liquid cooling and a power valve exhaust port, the RZ was built to be very robust. Capable of being reliably tuned to significant horsepower increases via compression, porting and bolt-on changes (with requisite carb jetting, of course), the RZ was something that could be enjoyed in stock form and could continue to grow. Today while RZ-specific tuner parts are not readily available (after all, this model has not been sold for many, many years), the aftermarket quad scene is still going strong and there is a lot of knowledge about these motors in that community.

From the seller:
Up for sale today is a very low mileage 1984 Yamaha RZ350. The bike is is very good condition and in excellent running order. It starts on first or second kick every time and everything operates as it should. There are 2 small dents on the left side of the tank about the size of a quarter and nickle respectively that someone touched up and the rest is normal wear in my estimation. The paint shows very well and the only no oem items on the bike are the mirrors,exhaust and air filter ( has a K&N on it now but I have the original airbox that goes with the bike.

The last several RZs that we saw pass through eBay showed strong bidding and a significant amount of action. That speaks to the popularity of these bikes. This is especially true for those that are in exceptional condition and include the rare – yet power robbing – original parts such as the catalytic converter exhaust pipes. This particular bike appears to be in good condition, and sports period-correct mods such as the airbox and expansion chambers. The seller notes some minor damage to the tank (not particularly well shown in the pics) and non-standard mirrors (the original RZ items are round). But with lower mileage and an overall clean appearance this could be a good buy if everything else checks out. The going rate for a great RZ these days tops the $10k mark, so set your barometers accordingly. This one sits just below $6k with only a few days to go. Check it out here, as we don’t often see these bikes hang around long at auction. If your’re itching for something to collect, something to ride, something to hot rod – or maybe all of the above – you’d be hard pressed to do better than a RZ350. These are still relatively affordable, and all the fun you remembered. Good Luck!!
