Purity of Purpose: 1981 Yamaha TZ250H

1981 Yamaha TZ250 R Front Naked

The 1981 Yamaha TZ250 more than just an evolution of their 250 GP machine, it was a complete reworking that shared almost no parts with the older bike. It included an entirely new engine designed around features from the proven TZ500 that were intended to increase both power and reliability.

Keep in mind: the TZ250 is no production-based entry-level racer, and running one is not for the faint of heart or mechanically inept. “Improved durability” is a relative term: the TZ250 will still need rebuilds every few hundred miles, making it a very expensive hobby or a labor of love, depending on your level of mechanical aptitude… But the feeling you’ll get from riding a genuine race bike, combined with the emotional and historical link with famous riders who got their start on a TZ makes the cost and effort worthwhile.

Racing motorcycles embody such an interesting duality to me, the contrast between the simplistic, almost primitive bodywork wrapped around beautiful mechanical bits. The sand-cast cases look very exotic if you know what you’re looking at, and that dry clutch adds another touch of race-tech bling. And those dull grey wheels? Magnesium.

The completely new 180° water-cooled two-stroke parallel-twin featured a shorter stroke than the earlier machine, reducing piston-speed and improving durability. Carburetors were generally Mikuni, although this bike features a set of period-correct Lectrons in their place.

From the original eBay listing: 1981 Yamaha TZ250H for Sale

This TZ250 is a very good and complete survivor and is in a fantastic condition for a 34 year old race bike with corresponding frame and engine/motor numbers. The bike was in storage since 1990 and was started once a month and driven around the block by previous owner to circulate fluids. The bike has a new aftermarket fairing and the seat is a "New old stock (very old)" seat. Tank (original) and front mudguard (original) are in white primer ready for paint. The fairing and seat are in white gel coat finish. Tank has a few imperfections, but will take very little work to get it perfect. The tank does not leak!   This bike is fitted with a set of very rare lightweight Magnesium race wheels. The original full fairing and seat are included in the sale. The screen on the bike fits the original fairing, but is not a perfect fit for the new Airtech fairing and will have to be replaced by buyer for a better fit.

The frame was chemically stripped of all old paint and re-painted, see pictures. The wheels were also chemically stripped and now are in un-painted magnesium finish.

The bike is fitted with a set of racing LECTRON carburetors. The LECTRON manual is included with the sale.

Bidding is very active and is currently north of $6,800, with just 24 hours left on the auction. It could use some graphics to decorate those bare fairings. With so many cool parts on it, not the least of which those magnesium wheels and the Lectron carbs, this needs to be decked out in some vintage racing Yamaha racing colors, with maybe some period sponsor logos, then flogged mercilessly on track...

Some Assembly Required: 1986 Honda NS400R

1986 Honda NS400R R Side

Honda’s NSR400R was a snarling, two-stroke middleweight from an era of unprecedented experimentation; a three-cylinder, triple-piped sportbike with cutting-edge specifications. The 1980’s must have been a very discouraging time for European and Italian manufacturers. While they were barely hanging on by their fingernails, Japanese manufacturers were in the throes of an era of funky, experimental technologies, trying out new formulas, and nothing was off-limits: unusual engine configurations, turbos, and active suspension were all tried, with varying degrees of success.

1986 Honda NS400R R Rear Suspension

The NSR400R wasn’t lacking performance or technology: the rattling heart of the little monster was a liquid-cooled, 90° V3 that put 72hp through a six-speed transmission. Power-valve technology beefed up the midrange power while water-cooling increased power and kept mechanical noise to a minimum, although the snarl from the pipes is undeniably that of a two-stroke. Anti-dive forks and modular wheels wrapped in radial tires completed the package.

This is a rare Honda NS400R Rothman's edition 2-stroke. We got this jewel  from a retired motorcycle mechanic. Bike is not running and engine will need to be redone according to him. Honda appears to be complete with a couple of things missing like keys, exhaust, mirrors, gear shifter lever, kick start lever, and coil cover.  Paint and fairing is nice with some scratches. Mileage is really low at  4,741 Km. Bike has a small decal with Japanese writing and No. 301 If someone can tell me the year or more info please feel free to do so and I will update the auction.  BIKE IS SOLD WITH A BILL OF SALE BUT If winning bidder wants a title we can obtain it at additional cost  just contact us.

1986 Honda NS400R L Fairing

Just two days left on the auction, with bidding just over $3,000 and the reserve not met. While this bike isn't 100% complete, the bike is in cosmetically good shape, and the parts missing are fairly straightforward to replace. Those missing pipes might be difficult or possibly expensive to source... So why not go all-out and, since you're going to have to rebuild the engine anyway, just have someone whip up a set of pipes with custom expansion chambers, all out of titanium while you’re at it?

All the Toys: Honda NSR250

Honda NSR250 R Side

Here's one from Craigslist in South Carolina, a Honda NSR250. The NSR250 was a roadgoing two-stroke v-twin sportbike that's been largely forgotten here in the Land of "Bigger is Better," where two-strokes have long since vanished from the road. But among those in-the-know, they're much sought-after by collectors and fans of the two-stroke Moto GP era, and riders looking for a light, fast track day machine that stresses finesse over brute power.

Honda NSR250 R Side Front

250's are often associated with the derogatory "learner bike" epithet, but it's obvious at a glance that this is no commuter or toy: triple disc brakes, aluminum frame, and single-sided swingarm scream "high-performance" and the six-speed cassette gearbox obviously offers no real benefit for a street bike... The NSR's little 249cc v-twin featured about 45bhp stock, but can be tuned to make as much as 60 without breaking a sweat, and that makes for a potent package in a bike that weighed in under 300lbs dry.

Honda NSR250 L Side Rear

In addition, this example features a host of tasty, high-spec upgrades to the bike's components, swapping in lighter, or higher-performing items to increase racetrack prowess, although it still has road-legal lights and signals. It looks to be in great shape, but there's a bit of a fly in the ointment... From the original Craigslist posting: Honda NSR250 for Sale

Honda NSR250 titled and street legal in SC. Bike is in very nice condition, but it is not 100% original so I am pricing accordingly at $8500 obo with SE wheels and stock credit card PGM, or $10.5k obo for SP wheels and PGM with stock and HRC credit cards w/ other HRC upgrades:

1) Titled in SC as a 2008 ASVE NSR250 w/ an assigned VIN# different from the original. That means the bike was reassembled in 2008, and I could not use Honda's name. This has nothing to do with salvage, so everything is perfect with the paperwork, and both VIN's show on the bike and coincide in the DOT computers in TX and SC. I originally titled it in TX in 2008, and then moved to SC in 2010, and titled it in SC in 2014.
2) Frame is not original 1995 SP since original frame was altered by first US owner in Washington State, therefore I have a different frame that does not have the '95 SP series VIN #, but I suspect it was a '94 or '95 frame.
3) I sold the original SP forks and it now has SE forks on it. They look great and were rebuilt recently.
4) I do not run oil injection and I do not have the parts, but they are available on ebay cheap.
5) 1995 SP Dry Clutch Motor is fully rebuilt with less than 50 miles on it. It is awesome, pulling small power wheelies in partially restricted mode/stock carbs in 1st and 2nd gear. Wiring is stock and not spliced yet.
6) JHA aftermarket pipes with Tyga silencers
7) HRC airbox with Hi-Flo reeds, stock carbs, and Uni-filters
8) HRC single core radiator, hose, lower head conversion, and overflow system with no thermostat - continuous flow and works great
9) Penske Rear Shock that was rebuilt/sprung by Thermosman
10) Very nice 1995 SP bodywork with an excellent OEM spare upper fairing
11) 1995 SP Tank was repainted with original OEM decals and then cleared over - looks very good.

Honda NSR250 Dash

The list goes on, and includes modifications and updates. Those modifications destroy the originality a bit, but it uses appropriate, high-quality parts that should improve performance and look very trick... Unfortunately, the price seems a bit on the high side, considering those title issues that the seller mentions. Whether or not this will present a problem for you will depend on where you live and your intended use: many state DMV's have relatively lax rules, but the iffy status could cause problems if you try to register it in someplace like California or New York... So, caveat emptor.

Of course, if you buy this as a track bike, a role for which it should be ideally suited, you can sidestep that whole problem.

Honda NSR250 L Side Front

So: a great-looking rider, not a collector. A really, really nice "bitsa" as the Brits say. If your local DMV doesn't object to the funky title, this will be the perfect tool to terrorize your local back roads. If they do object, sell the lights and street bodywork on eBay, fit some lightweight panels, and have yourself a grand old time passing much bigger machines on the brakes and in the corners at your local race track.

Even Better Than the Real Thing? Yamaha YZR500 GP Replica

Update 12.31.2014: We first saw this GP replica in July when it failed to get any action with an opening bid of $26k. It's back on eBay now with a buy-it-now of $24,500. Happy New Year everyone! -dc

This Yamaha YZR500 GP Replica is the rarest of the rare, a one-of-a-kind opportunity to buy a one-of-a-kind motorcycle. Meant to recreate Yamaha’s iconic year 2000 OWK6 racing machine in the classic Marlboro livery, this bike may not be the original article, but is a hugely impressive machine in terms of the enthusiasm and money invested. Powered by a tuned 500cc V4 two-stroke engine and suspended by Yamaha R6 bits, with an authentic replica frame and bodywork, this might be the closest you’ll ever get to riding an actual GP machine.

2000 Yamaha YZR500 Replica L Front

I am no expert on these bikes, so I’d love to see the peanut gallery weigh in as to the accuracy of this replica. I’ve been next to full-on WSB and Moto GP motorcycles and it’s always interesting to me how they still basically look like motorcycles. Racing cars, especially Formula 1 machines, really look nothing like actual cars, aside from the four round rubber bits. But racing motorcycles? It’s the details that really impress, since they have the same basic silhouette as their road-going counterparts, but chock-full of amazing details.

2000 Yamaha YZR500 Replica L Side Engine

From the original eBay listing: 2000 Yamaha YZR500 GP Replica for Sale

A replica of the legendary Yamaha YZR500 from year 2000. Based on a chassi handbuilt in aluminium by Mick Costin "Costin motorcycle enginering" Sydney Australia. An exact replica but made to accept the Yamaha RD500LC 2 stroke v4 engine. Also rear sets and suspension linkages comes from Mick. This one has a 1985 1GE engine rebuilt with new bearings, oil seals, clutch, pistons, and it is tuned "TSI mods" done by Orluff racing in sweden. 1 mm overbore. Samco silicon hoses for the modified Yamaha R6 radiator, Jim lomas custom made exhausts in stainless steel with carbon silencers. New Mikuni TM28 flatslide carburettors with new K&N Filters. The bike was run in a dyno bench in may 2014 and has 99 hp on the rear wheel. Forks, triple clamps, swingarm, rims and rear brakes comes from a 2006 Yamaha R6. Rear shock and front fender in carbon comes from a Yamaha TZ250, PVM radial front brake master cylinder, goodridge steel brake hoses to tociko 4 pot calipers. Galfer wave brake discs front and rear, new galfer brake pads, Fuel tank is a heavy modified unit from a VFR400 nc30 with a Pingel dual outlet fuel tap. Fairings are copys in glasfiber made by Motoforza from a 2000 YZR500 painted in Marlboro red. Standard RD 500 tacho and temp gauge, New Regina 520 chain and Afam alu sprockets, Only scrubbed in Michelin power supersport tires, The bike has only been ridden twice since it was built. I have many more pictures taken from building this bike that i will send to seriosly intrested buyer.

2000 Yamaha YZR500 Replica R Rear

I’m seriously impressed with the dedication and money that went into creating this motorcycle, but I’m not actually sure what you’d do with this thing after you buy it: it’s not the genuine article, so it’s a tough call for collectors, and it’s very, very pricey for a track day or vintage racing junky. On the plus side: you can actually ride it, without worrying you'll crash a priceless and historic racebike.

Or maybe, if you live in a more permissive state, it can, as the seller mentions, be registered for road use… How hilarious would that be? Suction cup a little projector-beam headlamp and a bicycle taillight, a pair of LED turn signals… I’d read recently that Britain actually has a special “track bike” MOT that allows limited use of track day bikes lacking the usually required road equipment to get to and from the racecourse during daylight hours.

2000 Yamaha YZR500 Replica R Side Engine

It’s certainly a very nice curiosity, and one I hope finds the right buyer. At $27,000 with the Reserve Not Met, that’s going to be a tall order. Please also note that the bike is currently in Sweden, if you didn't notice the non-USA license plates on the cars in the background of the photographs. Regardless, there’s very little time left on this auction, so move quickly if you want to get your hands on this one-of-a-kind motorcycle!

Small and Mighty: 1998 Cagiva Mito

Mito_2

If you were hoping to park a 916 in your garage but don't have the stature - either physically or financially - this Cagiva Mito might just be for you. Highlighted in the past as a mini-916, the Mito is a 125cc single cylinder two stroke sport bike that resembles a much larger machine. That resemblance is far from accidental, as the famed Massimo Tamburini had a hand in restyling the bike after its initial introduction. Mk I machines were shipped from 1989 - 1993, while Tamburini's Evo I & II models started shipping in 1994. The three spoke wheels and 7 speed gearbox identify this as an Evolution I model.

Mito_3

From the seller:
This machine is virtually new as it only was ridden 399 km since its conversion from a stock 70mph (110 km) bike to one that will show 112 mph(180km) on the speedo.Its collectibility is enhanced by its 7 speed gearbox and of course the styling, which was done in the spirit of the Ducati 916.Being a 2 stroke machine,many states allow small displacement bikes plates for highway use or find a track site to enjoy this super handling lightweight. The mods we performed were not optimized for competition, but were done to keep the reliability and add to the enjoyment of the bike.Recently upgraded, cleaned fuel system,and new battery was fitted.

Mito_1

If you live in a state with emissions laws, this might be a challenge to register and would best be a track-day only bike. If you are concerned with the Mito's tracking creds, you will note that Valentino Rossi's first championship race bike was a Cagiva Mito. He certainly has no issues with credibility; just look what the Mito did for him! If you *are* able to register this little gem in your state, please don't rub it in; we're jealous enough. Really.

Mito_5

This bike is located in Syracuse, New York. Action has been moderate, with the latest bid sitting below $3k and a reserve in place. It's impossible to tell what the seller has the reserve set for, but it is unlikely to be met at the current rate with the time remaining. Check it out here and share your thoughts. What's a fair price on a unique Italian smoker here in the States?
