Smokes-Branded Smoker:1985 Yamaha RZ500 for Sale

1985 Yamaha Marlboro RZ500 L Side

A wild race-replica from the era of two-stroke Moto GP machines, Yamaha’s RZ500/RD500LC was a direct competitor to Suzuki’s RG500 Gamma. Never officially imported to the US because of emissions laws, many have found their way south across the Canadian border.

The bike was powered by a liquid-cooled 50° two-stroke V4 with twin cranks. Midrange torque was boosted by a pair of Yamaha’s YPVS power valves and lubrication was handled by Yamaha’s suggestively-named Autolube oil-injection. Interestingly, the engine featured a balance shaft to smooth out vibrations. This not only improved comfort for street riders, it also allowed the frame and other parts to be built lighter, since they didn’t have to endure as much shaking. Engine cases were magnesium, as you can tell by the fact that “MAGNESIUM” is cast into them.

A six speed box with a conventional wet clutch put 88hp to the 18” rear wheel. In most markets, the frame was steel, although Japan’s home-market RZV500R featured an aluminum version, with lighter weight offset by a detuned engine that produced 64hp. The rear shock was mounted horizontally under engine, clearing space for upper cylinders’ expansion chambers and the battery. The front end featured anti-dive and a 16” wheel.

Clean WI Title – Original Owner

Engine is stock with less than 100 miles since it was freshened up with NOS parts July 2013 18,650kms on the odometer @11,500 miles

Besides the standard bore original parts engine rebuild the bike was gone through in late 2013 with new parts everywhere else they were needed, wheel bearings, cables, brake calipers rebuilt, new brake pads, forks rebuilt w/ stiffer springs, oil pump & hoses replaced, new battery, new tires, etc. Starts, runs and rides great.

Non-original items listed: 
Brembo full floating front rotors – very rare (originally for FZ750)
Stainless brake hoses
Fiberglass solo tail section & seat
Rearsets have no provisions for passenger footrests
Samco coolant hoses & clamps
Shorai sealed battery
New O-ring chain & sprockets
Platinum Pearl white & Marlboro Racing red custom paint with UV stable clear coating. Stickers are on top of the paint.

So, not completely bone-stock, but the upgrades are appropriate and should improve the functionality. I can personally vouch for the Shorai battery: I stuck one in my Ducati and the light weight and difference on starting compared to stock are pretty amazing. Although the Marlboro paint scheme might not be to everyone’s taste, I like it better than the factory style…

(puts on flame-proof suit)

There are 4 days left on this auction, with bidding up to $8,100 at the time of writing, so we'll see just how that vivid paint affects the price for this one!

The Right Snuff: 1986 Suzuki RG500 Gamma

If you are looking for the big dog of the two stroke world, few would argue that the 500 Gamma is the way to go. With a compact, twin crank, square four configuration (same as the GP racers), the RG is a favorite for modders and hot rodders alike. In this particular case, today's bike has been transformed from a stock RG into a Skoal Bandit GP replica with the creds of Rick Lance to back it up with performance. This thing looks very, very sweet and is certain to fetch a serious price.

Looking at this paint job makes me wonder why Suzuki didn't churn out more than the reported 150 genuine replicas. I find the color striking, and very applicable on this smoker. While the seller does note the paint is all new, it is unclear if this bike started out life as a Skoal replica in the first place. The most telling item missing is the hideous green seat that is found on a genuine Skoal stocker, but given how much has been changed on this bike I wouldn't blame the seller for swapping that out for a better looking unit. As the Skoal bikes were simply a respray of the standard RG (with absolutely no performance differences), does it really matter what the starting point was? This bike could have started life as a Walter Wolf edition for all I care.

From the seller:
Up for sale a 17 Digit VIN clear titled Rick Lance full performance built Skoal Bandit RG 500. Getting very difficult to find one as good as the claims?, Well, you have now found it!! Suzuki waited 11 years before releasing the square four RG500, a brilliant half-litre sports two stroke. The fact that the street version which has been properly modified in Rick Lance fashion is as potent as the 1976 World Championship winning RG is quite astonishing.

NOW IS YOUR CHANCE TO OWN IT!!!!!
The outstanding features of this machine are as follows:
Rick Lance Big Bore motor which is inclusive of Rick's exclusive "O" ring machined heads.
Jim Lomas Torque Pipes.
Offset bored carburetors to 31.5 mm.
Rick Lance Supplemental Fuel petcocks.
Rick Lance Air Filter kit.
Rick Lance Clutch upgrade which yields outstanding performance vs. the issues of the past regarding the Gamma characteristic "drag".
Maranello Transmission upgrade.
Rick Lance Battery relocation.
Rick Lance Oil in frame, stock oil tank elimination modification.
SV 650 Black powder coated wheels mated to Michelin Power Pilot Radials
EBC wave rotors.
Front fork Gold Valve emulator kit/ with full Rick Lance fork tuning and Spring set.
Rick Lance specifically designed rear shock/ with Lance ride height adjuster.
Rick Lance braced and polished swing arm.
Lots and lots and lots again of polishing work as evidenced in the pictures.
AWESOME, Skoal Bandit paint scheme.

You cannot look at this bike and tell me it doesn't appear completely awesome. Apparently most of the folks that stumbled across it on eBay agree, because the current bidding above $30k with a reserve still in place. Anyone care to guess what this one will go for? Check it out here, and then share your thoughts. It's not easy being green, but this one pulls it off with aplomb. Pardon the pun, but this one really does have all the right snuff!

Two-Stroke Triple: 1985 Honda NS400R for Sale

1985 Honda NS400R R Side

This Honda NSR400R was up for sale recently, but did not find a buyer. Hopefully, it will sell this time around! After years of relatively conservative technology, where overhead cams were considered pretty cutting-edge, motorcycle design went into overdrive during the 1980’s and the Japanese, fueled by their 1970’s domination of the market, were at the forefront. An exciting new era of electronics and a futuristic mentality that sought to redefine what a motorcycle could be led to all kind of striking experiments in technology.

1985 Honda NS400R R Side Front

Their looks and electronically-actuated suspensions were just the tip of the iceberg: engine configurations also varied wildly. All of the major manufacturers experimented with turbos, and you could find inline four-cylinder cruisers, straight-six standards, and two-stroke V3 sportbikes, like this Honda NSR400R.

The NSR400R was powered by a liquid-cooled, two-stroke 90° V3 that put 72hp through a six-speed transmission. Water jackets quieted the stroker racket, displacement made for more torque, and Honda’s power-valve fattened the power curve for very smooth delivery and made for a very polished package. Combined with light weight and excellent suspension, it was one of the best-handling bikes of the period.

Beautiful Dream: Bimota 500 Vdue for Sale

Bimota VDue R Side Front

The Bimota Vdue should have been epic: it was supposed to be the very first Bimota designed and built completely in-house, powered by a proprietary engine with cutting-edge technology. Bimota got their start building lightweight exotica around existing engines, but this would take their bikes to a whole new level and the spec sheet reads like a resume for the racetrack refugee that it was: a 500cc two-stroke v-twin pumping out 110hp. Cassette gearbox. Carbon-fiber bodywork and a dry weight just north of 300lbs. Top-of-the-line suspension front and rear.

Bimota VDue L Side Front

But not only would this machine offer a nearly GP-level experience, it would single-handedly save the roadgoing two-stroke. The all-new engine featured a state-of-the-art, electronic direct-injection system to keep emissions of the fundamentally dirty two-stroke engine within acceptable limits.

But the tiny Italian firm overreached themselves and what should have ushered in a new era for Bimota actually sank the company: the first batch of bikes was a disaster. While the bike was, of course, amazingly agile and fiendishly powerful, it was nearly impossible to ride smoothly. It delivered on the promise of a light-switch, two-stroke powerband, but amplified with hideously inconsistent fueling that made it nearly unrideable.

Bimota VDue Dash

Seized engines were common, and buyers soon began demanding their money back.

The problem was eventually blamed on manufacturing differences in port-height that was exacerbated when the parts were mixed and matched in production. Even worse, the problem was initially thought to be a mapping problem with the new ignition. But with inconsistencies between port-height in different engines, new maps that made one bike work fine didn't work on other bikes. It took a while to track down the actual problem.

Bimota VDue R Side Swingarm

Barrels were replaced under warranty, but the problem wasn’t really resolved. Eventually one of the engineers involved in the project bought the remaining unfinished machines after Bimota went bankrupt. He continued to refine the bike, dropping the troublesome injection and simply fitting a set of Dell'Orto carburetors for the Evoluzione Corsa version of the bike, and a few of these made it onto the road. Well, not really the road: the goal for the injected bikes was emissions legality, and carbs may have made the package work, but it wasn't generally legal.

Bimota VDue Tail

Ultimately, something like the full performance potential of the Vdue was realized, but the project sank the company, their envisioned triumph turned into disaster.

From the original eBay listing: Bimota 500 Vdue for sale

The only Bimota with a Bimota engine: 500cc v twin two stroke engine. Carby model with Jolly Moto pipes. This is a brand new bike never ridden with 2014 spec CDI and jetting set up. Bike has been tuned and runs perfect at a press of a button, ready to go. Parts are very cheap and easy to get no problem. There is a manual and spare keys that will come with the bike as well with the number plate mount.

Bimota VDue Exhaust

The performance potential is huge, but these are true exotics and require real dedication to own, in spite of the seller’s assertion that “parts are very cheap.” Just fueling the thing could put you in the poorhouse: mileage can dip as low as 15mpg when ridden hard. Less than 500 Vdues were made, including the carbureted "Corsa" and "Evolutzione" models. It is truly exotic, with ambitious goals and technology. It’s also one of the best looking bikes of this, or any era: purposeful and sleek, with no gimmicks.

In an era when the Japanese were committed to their garish neon slash paint jobs and names like “Ninja,” “Thundercat,” and “Thunderace, the Vdue made do with a loud, but classically patriotic paint scheme and a name that was about as simple as you can get: “Vdue” translates directly to “V-twin.” Everything sounds cooler in Italian. Who else could name a car the “Four-door” and make it sound cool?

Bimota VDue R Rear

$30,000 starting bid is pretty steep, but seems to be in the ballpark for these, although it's not really clear what year bike this is. There’s been virtually no interest in the bike so far, with no bids and just four days left on the auction. The bike is currently located in Sydney, Australia, but it’s unlikely to be road-legal wherever you are without some legal wrangling. But out on the track, this should be killer and you'd probably manage to pass people because they'd just want to watch you as you go by...

This one is a 10! 1985 Yamaha RZ350

RZ350_7

The last of the factory two strokes to be imported into the United States (and even California!), the RZ350 continues to be a fan favorite despite the relative lack of rarity. A decent RZ can be found pretty much any day of the week in the US or just across the border in Canada. The trick is finding one worth the effort; many RZs have been thrashed within an inch of their screaming two stroke lives and then hung out to dry. Today's RZ is a little different. If you want original, this one looks like it. If you want clean and not abused, this just could be your bike. If you want low miles, this one has but TEN. Claimed to have been in a private collection, this "new" RZ is located in California and looking for a new home. To my eye it needs some vitamin D courtesy of the warm California sunshine, and plenty of exercise. A regular regiment up Malibu canyon could work. Any takers?

RZ350_1

From the seller:
One of a kind. Just came out of a private collection. Has never been in the sun for more than 20 minutes. Pristine collectors bike. Not going into tons of detail. Google brand new RZ350 and that is what you get.

RZ350_5

I definitely hear this bike whispering my name (somewhat hoarsely, as it has not had a voice in a long, long time). Unfortunately I am not feeling a lot of love from the seller. For such an unbelievable offering (nearly brand new RZ350, not restored or resto-modded) this bike deserves some great, high resolution pictures and LOTS more information. Yes, we all know about (and love!) the venerable RZ, but this feels like a half-hearted attempt. I do not fault a fortunate (or savvy) individual who is looking to score 15 large US greenbacks off of this opportunity - after all, there are nearly none of these bikes left in this type of condition - but as a lover of the breed this bike deserves better billing. At least the model year was corrected (was listed as 1987).

RZ350_3

I'm sure there is someone out there with the desire and the means to own this bike...I can only hope that if it sells it will get to run free on American highways once again. The world needs a little more ring-a-ding-ding; especially California. And using the stock exhausts with cats in the pipes you can even feel good about the noxious fumes. Take that, Prius pilot! Check out the scant details here, and let us know what you think. Would you ride it?

Pint-Sized Racer: 1992 Moriwaki MH80R

1992 Moriwaki MH80R L Side

If you watch Moto GP, particularly the Moto2 and Moto3 races that are an exercise in mayhem for the first couple laps, you may be familiar with the Name “Moriwaki.” With frames competitive at the highest levels of racing, you’d be hard-pressed to find something with this kind of heritage and performance at anywhere near an affordable price… Unless you’re okay starting small.

This Moriwaki MH80R is powered by Honda’s CR80 two-stroke dirt bike engine and was designed to provide an affordable, entry-level racing machine. It used as many Honda parts as possible to keep initial and running costs as low as possible. This particular example has been bored-out to 100cc’s and a dyno sheet included in the listing shows 24hp. In a bike that weighs less than many riders, that’s no joke, and should provide plenty of performance for anyone wanting to learn to race: outright power can cover up for a lot of sins and teach lazy habits as you’re learning the fast way around a racetrack.

You won’t have that problem with this little MH80R.

1992 Moriwaki MH80R R Side Rear

At this level, you need to carefully shepherd every horse, slipstreaming bikes in front to build up speed for a pass, willing yourself to be smaller to fit in behind the windscreen as you cling to the tank like a motorized lamprey, using the brakes as little as possible, and hanging on to every mph for dear life.

1992 Moriwaki MH80R Dash

From the original eBay listing: 1992 Moriwaki MH80R for Sale.

Selling my Moriwaki MH80R GP bike, setup for CMRA F4 Sprint competition. This bike is a gray market import from Japan, and I bought it from another racer at the end of 2012. The motor is from a Honda CR85, and has been built to 100cc displacement by local guru Billy Wiese using a stroker crank and the Wiseco 5050 piston kit. Brand new topend (zero hours) installed by AF1 Racing, where it was dyno tested and made within 1hp of a Aprilia RS125. The bike has magnesium wheels from a Honda RS125 and a front brake from a Honda CBR600 F3. The suspension consists of RaceTech emulators in the front and a custom RaceTech 3-way shock in the back, all built and tuned by Roger Albert of OnRoad OffRoad Cycles.

The bike easily outruns Ninja 250s, given that it weighs well under 200lbs and can top 100mph. Selling because I've moved up to larger bikes for sprinting, and am only doing endurance races on lightweights. The bike is untitled, and I will include a bill of sale.

Many spares are included: Second CR85 engine (needs new bottom end); full exhaust system; clutch plates; original Moriwaki wheels and brake system (good for a rain setup); a full complement of front and rear sprockets; a box full of various gaskets, rings, spare parts, etc.

1992 Moriwaki MH80R Spares

The seller helpfully includes a pair of videos of the bike in action here and here to whet your appetite. With just about 24 hours left and a $3,000 Buy It Now price, this could be your chance to get a little track day toy that will teach you the Art of Momentum Conservation that will hold you in good stead as you move up to 600’s and 1000’s.
