Featured Listing: Zero-Mile 1987 Yamaha TZR250 for Sale

Are you looking for an '80s two-stroke to tear up the back roads in a cloud of blue smoke? Just move along: nothing to see here. Are you searching for a museum-quality Yamaha TZR250 2MA/1KT? Well we may just have what you're looking for with today's Featured Listing, a zero-mile example that may never have seen a tank of fuel in its life.

The very first TZR was a development of Yamaha's RD series of motorcycles, and it helped to define the rapidly-evolving class: lightweight aluminum beam frame, fully-faired bodywork, and a liquid-cooled two-stroke parallel-twin backed by a six-speed gearbox and a set of 17" wheels. Every bike in the quarter-liter class featured some sort of proprietary powervalve technology, and the TZR naturally used the Yamaha Power Valve System or "YPVS." Triple discs quickly became the class standard, although early TZRs like this one made do with just a single disc and caliper at the front. With a good set of pads, this should still pull you up quickly, considering the sub-300 lb dry weight.

First-generation TZRs and NSRs generally seem to command less money than their later counterparts and I'm not really sure exactly why. I'm assuming it's because early 250 two-strokes are nice, fun little sportbikes, while bikes like Honda's NSR250 MC28 from the end of the line pack cutting-edge tech and some trick parts... But as far as historical significance and style go, these early bikes have both in spades.

From the Seller: Zero-Mile 1987 Yamaha TZR250 for Sale

0 miles

Two stroke, not available in the United States, purchased in Canada. Extremely clean, near perfect condition. As far as I can tell, it's never had gas through the gas tank. New battery, original keys. Metric and US speedometer. A great addition to someone's collection.

The bike is located in Michigan to view and pick up. Not willing to ship but willing to assist with your shipper.

Price is $11,500. Please contact Joe at 517-404-8404.

As you can see from the photos, the seller even has the original service manual and a tool kit that obviously has seen minimal use. With zero miles on the odometer, it'd be a shame to put it on the road and wreck the pristine status, but if you're looking for an early TZR to complete your Yamaha sportbike collection, you're obviously very unlikely to find one in better cosmetic condition.

Some Assembly Required: 1989 Cagiva 500GP V589 for Sale

We don't normally post project or incomplete bikes here on RSBFS, but this one seemed too good to pass up: one of Cagiva's inspired but ultimately doomed series of 500cc GP machines, the V589. Battling against the established giants, Cagiva originally experimented with an inline-four configuration but eventually followed Suzuki's successful formula with a square four, before switching to a V4 in 1986. They may have struggled to win races, but if bonus points had been awarded for looks, the Cagivas might have stood a better chance, since they're considered by some to be the prettiest racebikes of all time.

Even if you don't agree, the specifications are certainly stunning: in an effort to keep up with the more established players, Cagiva experimented with some really wild technology, considering these were racing in the late 1980s and early 1990s. Extensive use of carbon fiber, traction-control, and electronic suspension were all tried to give Cagiva a competitive edge, although consistent success eluded them and they withdrew from competition at the end of 1994.

Earlier machines like this one had clear stylistic links to the Ducati 916 and Cagiva Mito which should be no surprise, as the V589 was designed by Massimo Tamburini. Some versions included a carbon fiber swingarm, although this one has the aluminum version. Much of this V589's bodywork is missing, but that's no surprise as those bits are pretty expandable on a race bike. Fortunately, it has the all-important frame, although it sounds like that will require some changes to re-orient the shock, as it was modified at some point to try an alternative configuration.

From the original eBay listing: 1989 Cagiva 500GP V589 for Sale

This is a genuine 1989 Original Factory Works Cagiva V4 500 Grand Prix race bike, as ridden by Randy Mamola etc. It is sold as an incomplete project and is for restoration.

The engine has been rebuilt recently and is fresh but I would still check it as it's stood for a little while. The factory records confirms the original build date of 23/06/89. The frame is chassis 4, it has a special fuel tank which was used to test the ignition in the tank area and also modified to try a top mount shock rather than the original horizontal fitting. The swing arm and shock are the original horizontal type so the frame would need reverting to take the horizontal mounts. There is a linkage arm, the shock is a special Öhlins 500GP unit made for Cagiva. The dash includes temp gauge, Magnetti Marelli ignition, rectifier, battery, PV controller. There is a radiator, coil packs, PV motor, magnesium wheels with front discs, sprocket, cables for throttle and pv, the complete triple clamp magnesium assembly, footrest hangers, rear master cylinder, cast water pipes, upper front fairing, belly pan with air box sections. There are exhausts and silencers but will need modifying to fit as they are later year. Some small parts also. So it is a very good basis. All the parts are original Cagiva GP but as the bikes changed constantly from race to race some parts are from varied dates and may need work to fit. Please study the photos to see what is included, everything is shown.

The main missing parts are fork legs (Marzocchi or Öhlins were used at various times) carburettors, brake calipers (Brembo or AP were used) seat unit, mid-fairing section, tacho, bars with levers and throttle, wiring, some other small parts.

I can put the buyer in touch with a collector who has other Cagiva parts to finish the bike.

The price for this one-of-a-kind bit of racing history? Just $55,000 but, considering the missing parts and what they will cost to track down or create, this is definitely an "experts only" proposition, but those of us with reasonable means can still look at the possibilities and dream...

Tiny Two-Stroke Terror: 1994 Yamaha TZ125 for Sale

A tiny racebike with big performance, the Yamaha TZ125 was a pure racebike and should not be confused with the TZR series of sportbikes. Handling was thought to be on par with the Honda RS125 but the Yamaha was down slightly on power compared to its rival. At 56mm x 50.7mm bore and stroke, it was oversquare, compared to the slightly underquare Honda, and featured Yamaha's "YPVS" to boost power. That little two-stroke single was backed by a six-speed gearbox with a dry clutch for extra lightness and improved rattle-osity. The owner's manual claims 180lb with oil and a full tank of fuel which means you may not need a ramp to unload your bike at the track if you work out regularly...

The listing for this particular bike is very... um brief and doesn't mention any spares, but several photos of parts are included, so I guess you can always email the seller if you want to know exactly what is included... Even if you're very familiar with the TZ125, some idea of what you're getting here would be a very good idea for the seller, especially since these are racebikes that need regular maintenance to keep them running and gearing/jetting changes to perform at their peak.

From the original eBay listing: 1994 Yamaha TZ125 for Sale

No title, no bill of sale, GP 125 for track, spares for a couple of seasons, ready to race. If you don't know what you're looking at. Don't waste our time. This is not a TZR our some sort of race rep. See pics.

The price seems reasonable at $6,000 considering what folks have been asking for other TZ125s but, perhaps as a result of the lack of details, interest in this machine has been pretty limited up until now, with just about 24 hours left on the auction.

Grand Prix Dreams: 1990 Honda RS125 for Sale

The second Honda RS125 that's been up for sale in the past couple weeks, this looks like a more bare-bones offering than the last one we featured, although it still appears to be in decent shape. If you're not familiar with the RS125, it's no "race replica": it's an over-the-counter competition machine meant for racing, not a stripped-down roadbike. Weighing in at 160lbs with a half-tank of fuel, it is powered by a very slightly undersquare 124.4cc two-stroke single that is backed by a six-speed gearbox.

These tiny two-strokes aren't for novices: the high-strung little engine makes a stunning 40+hp and that kind of power-to-weight means regular rebuilds, and shepherding the power from that tiny engine requires constant tuning and gearing changes to suit different altitudes, conditions, and tracks. It helps that the competition design means they're relatively simple to work on, but these are serious Grand Prix motorcycles, and potentially a stepping stone to bigger, faster bikes and more prestigious classes.

From the original eBay listing: 1990 Honda RS125 for Sale

Very rare Honda GP racer RS125, 125cc two-stroke single.
Very nice original condition.
1990 model legal to Vintage class racing.
Please see pictures for more detail.
Any questions please ask.
Will ship worldwide.

There's not much bidding activity so far and no Buy It Now price is listed, so perhaps this bike just hasn't found its audience yet, or maybe folks are looking for listings with more detailed descriptions? Is it the lack of extras? Spares for these little race bikes are very desirable, owing to the fact that they can be a pain to acquire and will be regularly needed if you plan to keep one running: 125s are often associated with cheap, reliable transportation, but the RS125 is a racing machine, and will require regular tuning and maintenance if the new owner intends to use the bike for its intended purpose.

Third Generation: 1990 Honda NSR250R for Sale

The MC21 was the third generation of Honda's lithe NSR250R, their entry into the quarter-liter two-stroke class that had been hotly contested by the major Japanese manufacturers since the mid 1980s. Power was modest, at least in stock form, but handling was cutting-edge, and the bike was packed with the usual wealth of Honda tech: PGM-III electronic ignition that used a three-dimensional ignition map for each cylinder and RC "Revolution Control" powervalve technology.

The NSR250R was motivated by a 90° liquid-cooled 249cc v-twin backed up with a six-speed cassette gearbox for bench-racing bragging rights and quick gearing changes at the track. From the factory, these were limited to 45hp by Japanese regulations, but more power is available from de-restricted bikes and today's machine is claimed to have a full compliment of horses. Triple disc brakes quickly brought the 300lb machine to a stop and both front and rear wheels were now 17" [earlier MC16 and MC18s had 18" rears] for modern looks and a slightly wider selection of modern rubber.

From the original eBay listing: 1990 Honda NSR250R for Sale

Up for auction is a beautiful 1990 Honda NSR 250 "R" model with only 8610 miles. The bike was legally imported into the United States.The bike has a clear US title with the proper 11 digit VIN number (title and frame number match). The bike has been de-restricted for full power. Bike starts first kick every time and idols perfect with no oil leaks. The bike is all original minus stainless steel brake lines, gas cap, rear set, and clutch and brake levers. Please view all the images as there are few scratches and scuff's throughout the bike. Also please keep in mind that this is all OEM factory Honda fairings and not the cheaper aftermarket stuff. All the electronics including horn, turn signals,high and low beam, and killswitch all work as they should. The carbs were recently cleaned as well as brand-new spark plugs and all fresh fluids. The bike also has a new battery and tires with less than 150 miles on them.  This bike is being sold locally and I encourage all bidders to come down and view the bike in person or send a local mechanic on your behalf to view for you. Rare vintage Japanese bikes don't come up often and this is a beautiful example with no disappointment.  I'd also like to note that the bike can be titled in any state other than California. I do know that some NSR's are titled in the state but do not know the loopholes to get the bike titled in California. All other states are fine to be titled for street use.

The seller also includes a nice startup/walkaround video so you can feel a bit better about taking a chance on this particular two-stroke. Bidding is up just over $6,100 with the Reserve Not Yet Met and several days left on the auction. It's not in perfect shape, with a few scrapes, scratches, and missing fasteners, but there is very little corrosion or discoloration on the aluminum parts, and the seller claims those are the original fairings.

Mark 1 – 1995 Aprilia RS250 Loris Reggiani Replica #275 of 500

The fact that it's offered by a SoCal preparation shop specializing in Suzuki might be a reminder that the Aprilia RS250 used the 249cc two-stroke twin from the RGV250.  As enhanced by Aprilia's intake, top end, and exhaust, the RS250 had power that put 4-strokes with triple the displacement to shame.   This first-year race replica has low miles, excellent cosmetics except for one faux pas, and a newly rebuilt engine.

1995 Aprilia RS250 Loris Reggiani Replica #275 for sale on eBay

Commemorating Aprilia veteran Loris Reggiani but capitalizing on Max Biaggi's string of MotoGP championships, the RS250 brought GP technology to the showroom floor with the sculpted aluminum-magnesium alloy frame and swingarm, and carbon fiber seat subframe.  Bigger-bike Marzocchi suspension and Brembo brakes alert you to the possible speeds.  The full fairing is sleek and completed by details like factory billet rearsets.

 

Another victim of too many bikes / too little time, this RS250 has under 6,000 miles and looks great except for the right seat fairing, which might be remedied with a decal kit.  Not sure it's the best thing on a low mile machine, but the fresh engine rebuild will require break-in and tuning, as the owner states in the eBay auction:

But probably the BEST THING about this bike is that it just had a full rebuild - crank, carbs rebuilt, pistons (rgv) new seal kit. Easy said and done over the internet  but i have photo's to prove.
The bike is supplied with full jollymoto pipes, but oem ones are included (seat,rear passenger brackets )
Owners books (both keys) and original loris poster with sales advertisement's
Bike does start but will need to be run in and maybe slightly tuned once its run in.

 

The small print for the RS250 included a powerband that doesn't begin until 8,000 rpm, so there might be a learning curve there.  Ready to ride at 350 lbs., handling is sharp and the brakes are world-class.  Aprilia's meticulous fabrication make the RS250, especially in the race replica, an exciting find...
