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: Tyga-Bodied 1988 Honda NSR250R for Sale

Today’s Featured Listing Honda NSR250R was one of the most iconic bikes of the late 1980s and early 1990s, at least if you lived in Europe or Japan. We never really got them here in the US, at least not officially. This tiny sportbike was a technological powerhouse, with Honda’s usual obsessive attention to detail, including an advanced electronic ignition system and quality components generally found on bikes with much larger displacements.

The 1988 model year means this is the MC18 version of the NSR250R, with a slightly undersquare 54 x 54.5mm 90° liquid-cooled 249cc v-twin backed up with a six-speed cassette gearbox nestled in between the aluminum rails of the frame. Engine management was via the PGM-II version of Honda’s sophisticated digital ignition matched to a powervalve to increase midrange power, in this case ATAC, an acronym for “automatic torque amplification chamber.” Power was quoted at the “official” 45hp, but more was available with tuning.

If you’ve just looked at the pictures, you might wonder why I’m talking about the NSR250R, since they appear to show something else entirely. But what you’re looking at is a highly modified MC18 with a complete set of Tyga bodywork, decked out in the classic Rothmans Replica graphics scheme. I’ve already lost those of you who know these bikes and prize absolute originality, fans who consider that Honda knew what they were doing, and that any deviation from their template is sacrilege have. Everyone else should read on.

The Tyga fairings honestly modernize the bike and the main giveaway that this is a thirty year old bike is the relatively conventional swingarm setup, as opposed to the “gull arm” version of the MC21 and the single-sider of the MC28. It’s not for everyone, especially the squinty headlights, but the swoopy tailsection that evokes the TZR250 and the curvaceous bellypan are very nicely done, and the whole thing is painted up in the classic Rothmans graphics scheme. Under the skin, you can see the stunning expansion chambers that indicate a higher state of tune, and more information on the details of this build at the Tyga Performance website.

From the Seller: 1988 Honda NSR250R for Sale

Up for sale is a fully restored custom build Honda NSR250. My Son purchased this bike while he was in Japan for four years. After he returned to the states he brought the bike back with him and gave it to me as a gift. Pretty cool.

I am a retired ex motorcycle guy and thought I was done with motorcycles. At any rate there were a few items that needed attention so I started to do some basic stuff. I installed a new rear YSS shock as the stocker was blown. Installed a new battery and I fully went through the carbs since it didn’t idle very well. During this time I had been looking at bikes on Moto2 Imports who specializes in two strokes like this and started a conversation with them about really doing the bike up proper.

The bike was then shipped to Speedwerks in Dover Delaware for a major renovation.

  • Steve Long is the master at Speedwerks who did all of the work on the bike.
  • First off the bike was the first MC18 to be fitted with the all new Tyga GP-T full fairing kit.
  • The bike was custom painted in Rothman’s livery and the paint is stunning in person.
  • While there the carburetors were fully gone through, the bike was de-restricted and dyno tuned.
  • The rear wheel was replaced with a 17” rear wheel from a MC21. Both wheels were cleaned, powder coated and now have new Michelin Power RS tires.
  • The bike has Tyga stainless steel expansion chambers and is equipped with their new shorty carbon silencers.
  • All of the wheel bearings were replaced and the front forks were resprung and fitted with new seals.
  • Both sprockets and drive chain are brand new and the battery was replaced since it was in the shop for a fair amount of time.
  • Both brakes have new pads and fresh brake fluid.

The bike was featured as the Tyga Bike of the Month and I will include the link for that article describing the build. The link below will detail the work that was done on the bike. The last thing is that Steve let me know there was some minor scuffing in the cylinders so they installed a full Tyga OEM top end on both cylinders.

As I mentioned I thought I was done with motorcycles as I am now retired but this was a really fun project to see it go from wow that’s cool, a NSR, to something that is now a museum quality build. I have ridden the bike about 15 miles since it was finished. I am too old to ride a sport bike anymore and hate to see it just sit so have decided to put it up for sale.

Price is $9500 OBO
Contact Cameron Kline: cmrnkline@gmail.com or +1 (817) 734-9201

This is a one-of-a-kind motorcycle, a very nicely prepared “restomod” that will hopefully find the right buyer, and the asking price should help that happen. It almost seems too nice to actually ride, but it’s been built to perform, should the new owner choose to put some miles on it. Honestly, it be even more a crime to just display it.

Featured Listing: Zero-mile 1997 Bimota VDue time capsule

CMG Motorcycles has two motorcycles on RSBFS right now, a 0 mile VDue and a brand new Bimota Tesi! Check them both out! -dc

There is no more tantalizing bike on the planet for me than the Bimota VDue. A bespoke Italian chassis from the finest boutique bike maker on the planet, draped with exotic suspension and prodigious brakes with fuel injection, the waistline of a ballerina and 110 or so two-stroke horsepower. A dream machine for the ages, it was supposed to kick Bimota into a new market segment in a cloud of sweet-smelling blue smoke. Instead, the dream went up like a Persian Gulf oil field and took the iconic nameplate down with it. 

Bad power delivery, seizing pistons, oil leaks plagued the first couple hundred VDues, and most owners returned them. Fixing the issues, which meant sticking carburetors on and invalidating the bikes for street use, ruined Bimota’s finances. Eventually, an engineer on the team that put the idea together bought the leftovers and fixed them. He sold about 120 that put out more than 120 street-legal two-stroke ponies, but by that point the toothpaste was out of the tube. 

This 1997 Bimota VDue never experienced any of those issues, because it has racked up exactly zero miles in its 22-year life. It is a literal museum piece in absolutely flawless cosmetic condition. Given the likelihood that its mechanicals are absolutely useless, both by design and from sitting, this thing is perfect for a collector who needs the finishing touch on a prestigious collection. 

Having never moved under its own power, it wears its original tires, which are now shiny from sitting around vulcanizing for a couple decades. But that’s no matter. When else will you get the chance to own a bike that is original and untouched down to the protective film on the windscreen? The thing we love most is that this bike is in its best state: an unblemished embodiment of bold vision and faith in engineering. It deserves to stay that way.

It is available in Christchurch, New Zealand for $48,990 USD and requests and inquiries can be sent to Brad by email  – here –.

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

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: 2000 Derbi GPR50R

Update 8.4.2019: Price lowered to $2999. Good luck to buyers and seller! -dc

Comments are optional on Featured Listings and enabled on this post so you can chat with the seller. -dc

Talk about punching out of your weight class. The 2000 Derbi GPR50R made its “49cc” brethren look even wheezier than usual when it hit these shores as a storm of silky handling hornets. Popular with new riders in Europe, the GPR50R is one of just a couple of examples of nearly full-size two-stroke 50cc bikes that made it here. 

Titled as scooters though they may be, the little Derbis cheated with a 75cc engine that was good for an astonishing 9.5 horsepower. That’s enough to get a sub-200-pound adult to close to 75 mph with a decent draft. They need to rev to the moon to get out of their own way, but once moving, the bikes do their best Grand Prix impersonation, with suspension and chassis characteristics of much bigger machines. 

As with any Napoleon complex street brawler, momentum — and clutch fanning — is the name of the game. 

This 2000 Derbi GPR50R has been kept quite beautifully, and does a fantastic job aping the legendary Ducati 916. A heady boast for such a reedy little machine, but the quality and pedigree are there to back it up. It has been treated to a Leo Vince exhaust, bigger carburetor, carbon fiber reeds and the afore mentioned factory displacement bump. The decals and livery are custom, and look great. The suspension has been reconfigured to accommodate a 200-ish pound rider, which should make day-to-day use a damn sight easier and more comfortable. 

From the seller: 

2000 Derbi GPR50R in Chicago

These were rare but official US imports and are titled as 49cc (scooters in most states) like the foreign versions.  However, US spec bikes came straight from the factory with the larger EBE075 motors and do 70+mph. This bike has 6,157 km (3,842 miles) and many upgrades;

Motor modifications

Airsal cylinder/piston kit (I have the original cylinder and piston in good condition)

Leo Vince exhaust w/titanium can

24mm Mikuni Carb w/throttle and cable

K&N air filter

Carbon fiber reeds

Carbon fiber oil pump block off plate

Cosmetic modifications

Red/white Ducati 916 SPS replica paintwork

Custom Cagiva-era 916 style decals

Rider’s seat recovered in black leather

Passenger pad recovered in red/white vinyl

Aluminum fairing fasteners

Additional mods

Doppler rear shock with heavier spring

Forks rebuilt and resprung by Superbike Suspension

Billet aluminum peg bushings

New chain/sprockets

New Avon Viper Stryke tires

The bike is fun to ride and with the suspension upgrades will handle a full size adult.  It is currently optimized for someone in the 200 pound neighborhood. There is a crack in the paint along the seam of the dummy tank (pictured).  There is a small nick in the paint on the right side tail piece, but I’ve got spares of both tail sides…and they’re already painted.

For just $3,500, you’re getting a cool piece of superlightweight history, made even more special by its imitation of much heftier and faster machinery. To get your hands on it, contact Adam at plus790@hotmail.com

Featured Listing: 1994 Honda NSR250R MC28 for Sale

Update 7.31.2019: This NSR250R is available for $12,500 and interested parties can contact Mark at mark@sloanvalley.com or 250-588-8775. Good luck to buyers and seller! -dc

If you’re a fan of four-stroke motorcycles, two-strokes like this Featured Listing Honda NSR250R MC28 can be a little… underwhelming, the first time you see, and especially hear one. I mean, even with aftermarket pipes, they make an oddly weedy sort of zing as they rev, and generally sound like you’ve strapped a couple of leaf-blowers with fueling issues to your bike. But fans know that’s the sound of a pure, simple, and utterly focused bike that emphasizes handling over brute power. And the MC28 was probably the most sophisticated of the breed and, until recently, very hard to get a hold of here in the USA.

The mechanics of a two-stroke are inherently primitive, and not very eco-friendly, since lubricant is mixed with the air and fuel in a constant-loss system that will spew heavy, oil-rich smoke from the tiny exhaust cans. But that simplicity means a two-stroke engine is incredibly light weight, and makes pretty spectacular power for a given displacement. If you come from a four-stroke mentality, a 250cc sportbike sounds very unimpressive, but bikes in the class weighed in at around 300lbs and could make as much as 55hp at the wheel when properly tuned, or even a bit more if you didn’t mind the occasional engine seizure…

The original NSR250R MC16 was introduced in 1987 and laid down the pattern the others would follow, with a 249cc 90° v-twin that featured an RC powervalve, and PGM electronic ignition, and a six-speed gearbox, wrapped by an aluminum beam frame. The final MC28 version of the bike seen here debuted in 1993 and added a slick ELF-designed Pro-Arm single-sided swingarm and trick PGM-IV electronic ignition system to the mix, making it one of the most advanced sportbikes of any displacement available at the time.

Today’s example has incredibly low miles and has had the wheels painted white to match the bodywork for an extra dash of 90s style. It’s currently located in British Columbia, but shouldn’t be too hard to register here in the US, depending on where you live. California residents, as always, should visit their local DMV with a sack of unmarked, non-sequential bills and a bottle of good scotch…

From the Seller: 1994 Honda NSR250R MC28 for Sale

Up for sale is a beautiful 1994 Honda NSR250R MC28 with only 1,000km  (622 miles). Bike is almost in mint condition. It had a stress crack on the right upper cowling around the blinker that has been professionally repaired. You can see the repair from the inside of the fairing but the outside looks perfect. All fairings are genuine Honda 100%. Bike is completely stock, like it was on the Japanese dealership floor in 1994. No dents on the tank (the tank itself was professionally cleaned and rust-proofed in 2018), one tiny chip in the paint. Wheels were professionally refurbished in 2018 and converted from red to white, which as a personal preference, was a game changer for how the bike looks. A brand new OEM rubber chain guide is included in the sale. Only a few handling marks not worth mentioning. Bike looks awesome. Just serviced with new fork seals (2017), new battery (2018), new engine fluids (2019), and Dunlop Sportmax Q-14’s installed front and rear in 2017. Runs like the day it was new.

This NSR was purchased from a dealer in USA in 2017 and can easily be returned to the USA market. I’m happy to deliver this bike to Blaine, WA 98230 to provide an easy loading point for any USA-based buyer. Bike is currently titled as a streetbike for road use in BC, and had similar title in USA. Thank You For Looking. Call 250-588-8775 for more photos or questions.

Price: $12,500
Contact Mark: mark@sloanvalley.com or 250-588-8775

Well, the completely stock condition might mean you’re stuck with Japan’s government-mandated 45hp, but the MC28 version is much harder to de-restrict than earlier versions and originally required a hard-to-obtain HRC ignition card to unleash the full power. For collectors, it means that the stock electronics and wiring harness haven’t been monkeyed with, and 45hp is still plenty of fun in a 300lb package, if the new owner plans to ride it. Aside from the minor fairing damage the seller describes and the non-original paint on the wheels, this thing should be immaculate, given the mileage.

Featured Listing: 1976 Yamaha RD400C

If you bought a mid-size two-stroke Yamaha streetbike in 1975, you got the very, very good RD350. You also got shortchanged, because buyers who waited just a year got the 1976 Yamaha RD400C, which Cycle World lauded as the perfect motorcycle, and which carried way more improvements than a simple displacement bump. 

1976 Yamaha RD400 for sale on eBay

The engine had been gone over with a fine-tooth comb, which resulted in the expected power increase, noise reduction and improved refinement at low rpm. Yamaha worked hard to keep the naturally antisocial two stroke as quiet and easy to ride as tech allowed at the time. The result was 35-ish rear wheel horsepower and a top end north of 100 mph, still impressive figures for a 400. 

The chassis got a good going-over, too, with new geometry that aped Yamaha’s all-conquering grand prix bikes of the 1960s and disc brakes front and rear. All that lined up to create the 1970s answer to the RGV250s and CBR400RRs of the late 1980s and early 1990s. The sublime reviews showed Yamaha’s efforts were well spent. 

This 1976 Yamaha RD400C is in fantastic restored shape, with a raft of powdercoated parts, a functioning oil injection pump and functional self-cancelling turn signals. It has been kept original with the obvious exception of modern rubber, so the experience aboard this thing will be damn close to what the guys at Cycle World felt 43 years ago. 

From the seller: 

For sale is a clean RD 400C for sale with a frame up restoration. Bike starts up first or second kick and very reliably. Bike is original to the finest details with original shocks and exhaust. Electronics gone through and checked. Original mileage is approximately 13027 miles. Titled and registered with California clean title in my name. Matching vin and engine numbers.

 Numerous work includes: 

 Motor has been gone through with new seals on the crank 

Powder coated frame 

re-coated nuts and bolts after complete strip down 

Powder coated numerous parts after strip down including swingarm 

New or refurbished parts include rubber parts, seals, gaskets and replacement worn parts 

New Bridgestone Bt45 tires with new bearings front and back 

All electronics work even the self canceling turn signal unit 

Tank is free of dents and has been resealed. 

Front and rear brakes rebuilt with new master cylinders and Caliper seals brakes work flawlessly suspension is supple in working order for original equipment 

new chain 

Oil pump intact with rebuild and adjusted 

Carbs synced and gone through with new rubber tip float needles no leaks here 

This RD was painstakingly gone through to keep to original condition. Although not absolute perfect would be a perfect addition to a collector. Starts and rides brilliantly for age and is great blast from the past with that unforgettable two stroke smell. Too good looking for me to keep and ride this bike is need of a new home with someone who will appreciate its heritage.

Laypeople often love cars and motorcycles with gratuitous stylistic frippery: air vents leading to nowhere, extraneous “engine beautification” panels to cover up the oily bits and wiring, unnecessary surface details to break up large panels. They don’t really understand the function of all those parts, or aerodynamic styling, so if it looks right, it is right. Purists also appreciate design, but often feel that good looks are a direct result of function, that that beauty is the natural result of effective engineering. Failing that, at least functional design has an aesthetic appeal all its own. Simplicity and lightness are especially important for racers, and sometimes the shapes that result look odd until you understand why they developed the way they did. In other cases, a pursuit of purity of purpose results in shape that just looks so right, like this Yamaha TZ250.

The TZ250 wasn’t simply a TZR250 with race plastics and the lights removed. It was  a pure racing machine, something privateers could buy directly from Yamaha and use to compete in Grand Prix racing. Everything on the bike is designed to help the bike make power, cheat the wind, or simplify servicing. Every component is as light as possible, and these featherweight machines are the model of elegant simplicity. Early versions were powered by a parallel-twin engine, but Yamaha switched to a v-twin in 1991, a liquid-cooled unit was basically one-half of the YZR500’s V4 and included a counterbalancer that made the engine much smoother, backed by a cassette gearbox for fast gearing changes trackside to maximize the bike’s narrow powerband.

The package was updated significantly in 1992, with subsequent changes amounting to a gradual evolution, refining and tweaking the package. The engine was updated in 1997 to allow the bike to run on unleaded fuel, as required by FIM regulations, while the 1998 version seen here introduced a sealed airbox with ram-air and oval-slide carburetors, along with revised bodywork that included the famous tapered tail.

From the original eBay listing: 1998 Yamaha TZ250 for Sale

I have a very, very nice 1998 Yamaha TZ250 4TW available. I purchased this bike in 2015 from a Southern California racer. It had been raced recently. I have done absolutely nothing to the bike, so it is still in as-raced condition. Overall its in excellent shape. The tank is flawless save for a very small dimple (about 1/8″ across). The bodywork is very good, but has a few imperfections here and there such as chips and scuffs. Normal racetrack wear. It has been stored in a heated storage facility with very low humidity here in Montana.

It has 190 miles on the top end and MCE racing crank. 2003 bodywork and airbox conversion. Includes PitBull rear stand, but no spares.

You can send your shipper here to my home in Red Lodge, Montana or I can deliver to one of several freight forwarders in Billings, Montana for attachment to a pallet.

The $14,500 Buy It Now the seller is asking for this TZ250 is a pretty good price, from what I’ve seen. It unfortunately doesn’t include any spares, which presents a headache if you’d like to use it regularly for race or trackday riding. You’ll obviously want to go through it thoroughly before using it, as it has been sitting for a couple years, but these are designed to be easily torn down and rebuilt, with crankshaft removal possible with the engine still in the frame and gearing changes to the cassette box taking only a half hour or so. Many TZs are being actively raced in AHRMA and other series, so I believe obtaining parts to keep them running isn’t prohibitively expensive, but these are a dying breed and represent the end of an era.
