Titled in AZ: 1985 Yamaha RZ500 for Sale

The two-stroke race-replicas like this Yamaha RZ500 represent a brief, very exciting time in motorcycling. The 1980s were a difficult time for bikes as well as cars: technology was leaping forward while emissions legislation stifled performance at the same time it attempted to save the planet. Eventually, manufacturers would find ways to work within or around these laws and increase performance to the point where today's 190hp literbikes, with incredibly sophisticated engine management software, ABS, and traction control, are useable by mere mortals without fear that they'll die the first time the throttle is wound to the stop. But the RZ500, Suzuki's RG500 and, to a lesser extent, Honda's NS400R were pretty wild for their time. They weren't the fastest bikes on the road, but they combined light weight and decent power in a package that rewarded skilled riders.

The RZ500, also known as the RD500LC in some markets, was motivated by a liquid-cooled 50° two-stroke V4 that featured twin cranks, with midrange torque boosted by a pair of YPVS power valves and lubrication handled by Yamaha’s Autolube oil-injection. Some engine parts were cast from magnesium for lightness and are clearly labeled "MAGNESIUM" for maximum bragging rights. A balance shaft smoothed out vibrations, which had the intended effect of allowing the frame and other parts to be lighter, as they weren't required to withstand as much vibration, while simultaneously making the bike smoother and more civilized, a feature that ended up backfiring on Yamaha a bit...

The claimed 88hp was transferred to the 18" rear wheel via a six-speed gearbox with a wet clutch, while the front end featured anti-dive forks and a 16” wheel. Packaging all four expansion chambers into a compact sportbike meant some unusual choices were made and the rear shock was mounted horizontally under the engine to clear up some space for the upper cylinders’ expansion chambers, as well as the battery. The Japanese-market version of the bike, the RZV500R used an aluminum frame in place of the steel part to save weight and offset that bike's reduced 64hp and, if you're not concerned about that bike's generally lower value, might make for a serious hot-rod when de-restricted...

The bike was never officially available for purchase in the USA, but many found there way here via grey-market import from our northern neighbors in Canada. Compared to Suzuki's RG500, the RZ500's most direct competitor, it was heavier, a bit less powerful, and noticeably more "civilized." It's still a 500cc two-stroke though, and power, although aided by the displacement and the YPVS, still has a pretty pronounced two-stroke powerband and that distinctive stroker sound. These have been generally less desirable than Suzuki's race-replica, but interest in this forgotten class has seen a steady increase in values.

From the original eBay listing: 1985 Yamaha RZ500 for Sale

A one-owner bike; I’m the original owner. Km: 14,678 ­­­Mileage: 9,120. Purchased November 15, 1986 from Year Round Yamaha in Calgary Alberta. Located in Glendale, AZ.

Details

This RZ500 is an original, completely stock example with no modifications whatsoever.  Full documentation including original Bill of Sale, all receipts, and complete maintenance and repair logs since new. Legally imported to the USA from Canada in June 1997. All import documents included. Clean Arizona title.

Includes

Both original keys, original owners manual, original tool bag and complete original tools, Yamaha Service Manual (Canadian Version), more than 100 OEM spare parts including many hard to find spares. Comes with magazines featuring the RZ500 from the period and a TAMIYA RZV500R model kit.

Condition

Very nice original condition, unmolested, unmodified, and extremely well looked after bike. There is nothing missing and all fasteners are correct OEM. The paint and metal work are excellent. There is a fairing crack in the lower left side fairing. This is covered by the belly faring and can’t be seen; however this should be repaired at some point. The bike is currently licensed and insured in Arizona and runs as it did when new.

Repair History

The bike has had two “garage accidents” resulting in a dented gas tank and a cracked upper fairing. The gas tank dent was professionally pounded out and repaired without any body filler. The fairing was plastic welded. Both the fairing and gas tank were expertly painted by Art Line Painting in Toronto. The bike also had a 3 MPH tip over resulting in scratches to the left fairing. This panel was also touched up by Art Line Painting in Toronto. The paint repairs are excellent and completely match the OEM paint. See photos or ask for specific photos and I’ll provide them. The motor has been repaired twice; once in 1994 (6,672 KM) to replace a crankshaft bearing and once in 2002 (10,656 Km) to replace a crankshaft seal. In both instances, no short cuts were taken; all seals, o-rings and gaskets were replaced in addition to the failed part.  

While the mishaps the seller describes are unfortunate, they're to be expected when talking about a bike that's 30 years old, and the repairs indicate the kind of attention that's been lavished on the bike to keep it in top shape. From the photos, it appears to be in excellent, if not perfect cosmetic shape and, as the seller indicates, been kept in original condition. The bike's titled status is a bonus if you're looking to use it on the road, but would also make a pretty nice collector.

Cali Plate: 1996 Aprilia RS250 for Sale

1996-aprilia-rs250-r-front

A mix of sleek styling and proven Japanese power, the Aprilia RS250 was the Italian company's entry into the hotly-contested quarter-liter sportbike class battles and intended to take the fight to Honda's NSR250, Yamaha's TZR250, and Suzuki's RGV250. The monochromatic style was a far cry from the vivid speedblock and tiger-stripe designs of the Japanese competition and has aged very well, and I bet plenty of folks would think this is a new, or nearly new machine.

1996-aprilia-rs250-r-rear

The RS250 borrowed its 249cc liquid-cooled two-stroke v-twin from Suzuki's high-strung RGV250, retuned for more power. Weight was competitive, at around 300lbs dry so the claimed 60hp made the bike plenty quick, with typical two-stroke power-delivery and serious agility. A sculpted beam frame provided a stiff foundation and the asymmetrical "banana" swingarm kept the bike's expansion chambers tucked in close to the bike for maximum cornering clearance. If those brakes look familiar, they're the very same Brembo units that stopped just about every other Italian sportbike of the period and are plenty powerful, considering those bikes were at least 30% heavier than the little Aprilia...

1996-aprilia-rs250-l-rear

I happen to prefer the earlier bodywork seen here, but later bikes have plenty of style as well, although their very 80s-looking dash is an acquired taste... Unfortunately, it's a little hard to see in the low-resolution photos that accompany the listing. The bike does include something that's a bit of a Holy Grail for RS250 fans though: a California license plate.

From the original eBay listing: 1996 Aprilia RS250 for Sale

Starts and runs may need some minor tuning. Have a sticker kit not perfect a few of the stickers are wrinkled thanks to FedEx. Have a rear seat cover that is purple. Arrows pipes, Toby steering damper.  

CA PLATE !!

Bidding is up to $5,000 with the reserve met and just 24 hours left on the listing. The photos are pretty poor, which is a real shame since miles are low and, aside from a couple of minor scuffs, it appears to be in good cosmetic condition. I wonder how much more interest there would be in the bike if the seller had bothered to include a few decent pics and maybe a short video of the bike, along with a better idea of what "may need some minor tuning" might mean.

11 Out of 10 – 1984 Yamaha RZ350

Evolving from the now-vintage RD350, Yamaha made a splash with the first perimeter frame for the RZ350, along with the YPVS power valve and rear monoshock.  Due to emissions concerns it was short-lived in the U.S., but this example is better than excellent.

Yamaha's 347cc parallel twin is water cooled and has oil metering, making its 50-plus hp at least less troublesome.  An early adopter of catalysts and vapor canisters, the RZ had a temperature warning light on the dash for the cats.  Emissions were also reduced by the YPVS ( Yamaha Power Valve System ) moveable exhaust port, and its rudimentary computer control extended the twin's powerband.  Elsewhere the bike was well-equipped for the day, with 32mm conventional forks, preload-adjustable rear monoshock, and 267 mm disk brakes disks all around.  The flowing lines of the tank and seat fairing were complemented by the handlebar mounted bikini up front, available in red/white or Kenny Roberts yellow paint.

Not often seen so original, this RZ350 comes out of Illinois with just under 7,000 miles.  Exhausts have been updated to expansion chambers and mufflers, but elsewhere it's surprisingly unfettered, and the factory finishes around the bike are beautiful.  Most often seen with a dual seat, this one has the sporty monoposto.  From the eBay auction:

Up for sale is a 1984 Yamaha RZ350 K/R. This bike is in Museum quality condition. Paint on entire bike is original and in like new condition. This bike comes with the single seat option. All dual seat parts are included with this sale. Bike has Chamber exhaust from HVC cycle. Carbs have been jetted for exhaust and a Y boot with a K&N air filter attached. Look, at all the pictures and check out the video attached, lots of info can be had from this. If you are looking at this bike then I'm sure you aware of its heritage and the somewhat rareness of it. There are only 3 minor flaws, 1- the windscreen on the bike has a crack about 1 inch in length. There is a brand new NOS screen in a box that will go with the bike. It has never been installed. 2- The speedo is what I call sleepy. After the bike sits for some time the bike has to be ridden approx. a mile before the speedo will register. This has been this way since I've owned the bike. Always works so I've left it alone. 3- There is a super small ding in the tank in the very front right side than cant even be seen unless your really looking. Just want to be real honest.  I didn't see it until I owned the bike for several years. I've owned the bike approx. 5 years and have never had a ounce of trouble with just regular maintenance.  The bike is being sold without a warranty and shipping is up to buyer. I can store the bike for a short time in a heated garage.

Light weight was always the RZ's unkept secret, fully fueled it was still under 400 lbs., allowing the limited horsepower, bargain suspension and diminutive brakes to work their magic.  Many of the model found their way to the track, or were modified for the street, but the RZ350 presented here has been spared most of that agony.  Likely to continue as an occasional rider or show bike, the original equipment and finishes make this Kenny Roberts edition very special...

“You Sending the Wolf?” 1986 Suzuki RG250Γ Walter Wolf for Sale

1986-suzuki-rg250-ww-r-side

The parallel-twin precursor to the well-known RGV250, the Suzuki RG250Γ "Gamma" was built between 1983 and 1987. Dry weight was a claimed 286lbs, helped by the aluminum frame, so the bike's 45hp can still move the bike down the road smartly. The little Gamma was styled to match the RG500, and was packed with technology to rival its bigger brother: dual front disc brakes, anti-dive front forks, Suzuki's Automatic Exhaust Control power-valve, and a six-speed gearbox. Tires are shockingly skinny, especially the 18" rear, but the low-mount exhausts look surprisingly modern on this classic sportbike.

1986-suzuki-rg250-ww-front

Styling is a bit slab-sided, but is helped here by the dark blue and red Walter Wolf colors, while the "W" branded gauge faces add a bit of flash to the otherwise functional dash. Although he sounds like the villain of a spy thriller, Walter Wolf was an Austrian-born, Canadian businessman who sponsored several Formula 1 racing teams in the late 1970s and then touring cars in the early 1980s. How they thought to use a limited-production motorcycle to advertise the brand is anyone's guess, but it did make for a good-looking machine.

1986-suzuki-rg250-ww-dash

Mileage on this example is very low and, although the bike isn't perfect, is in very good, original condition, aside from the stingers mentioned in the listing. Even the foam instrument-surround looks solid. The seller has been importing grey market Japanese cars like Skylines and Kei-cars and for a few years now, and appear to have branched out into motorcycles more recently.

Original Walter Wolf Key
OEM Fairings
Includes Spares
Includes Both Solo and Passenger Seats

This bike only has 4,836 ORIGINAL MILES! The Suziki RG250 Gamma was never originally offered in the U.S., but now that it's 25+ years old, we've been able to legally import it.   It's 100% Federally Legal and registration is like any other motorcycle. We have a valid Virginia title that is transferable to all 50 states.

This 1986 RG250Γ Walter Wolf example is in very good condition with just 4,836 original miles. The appearance is correct for the year with a red seat and wheel combination. The wheel size is 16” up front and 18” in the rear which was standard for the 1986 model. The only change appears to be a set of aftermarket mufflers and mirrors. The full aerodynamic fairings and exterior as a whole are clean for a motorcycle this age. There are a few light blemishes and a small crack on the right side fairing

The 247cc parallel twin two-stroke starts on the first or second kick and accelerates well with good pickup. Overall this unique and rare sports bike is mechanically sound and ready for its next owner. ***All of our vehicles come with a valid Virginia title, transferable to all 50 states, and a copy of the U.S. Customs release. All vehicles are located in Richmond, VA and shipping can be arranged to your front door.

You will not be disappointed with this motorcycle! We also have a number of spare parts available with this motorcycle.

This motorcycle was imported LEGALLY! It was NOT imported under a loophole, so there is no chance that it can be seized by the government. It will come with a CLEAN, CLEAR, VALID VA TITLE, and a U.S. Customs Release. **FEDERALLY LEGAL IN ALL 50 STATES**

1986-suzuki-rg250-ww-fairing

There's more than a week left on the listing, so there's plenty of time to snap this bike up at that $6,000 Buy It Now price. If you're looking for a handler, one of the more modern RGV250s is probably a better bet. But for that unadulterated 1980s experience, that seems like a very good price for such a clean machine. In spite of the sellers assurances, I'd check with my local DMV before bidding, but that valid title should make things a bit easier.

Museum Piece: 2004 Aprilia RS250 w/ ZERO Miles for Sale

2004-aprilia-rs250-r-front

What is there to say about the Aprilia RS250 that hasn't already been said? After other manufacturers had ceased building their quarter-liter race-replicas, Aprilia persisted, and this particular bike is one of the very last examples available: the model was discontinued in 2004, the year this bike was built.

2004-aprilia-rs250-r-rear

Powered by a revised version of Suzuki's RGV250 engine, the RS250's version of the little water-cooled, two-stroke v-twin produced power on par with the rest of the class, with an added dose of Italian style: the aluminum beam frame looks similar to the Japanese offerings on paper, but is far more sculptural and it's a shame it's partly hidden behind the fairing.

2004-aprilia-rs250-front

The "GP-1" on the rainbow-hued tailsection and in the listing actually refers to the second-generation RS250 introduced in 1998: it's not a limited collectors-edition as far as I know. This particular example may not be road-legal here in the USA, but it's basically a time-capsule machine that's ready for display in your collection.

From the original eBay listing: 2004 Aprilia RS250 GP-1 for Sale

Once in a lifetime opportunity to buy a brand new, old stock Aprilia RS250 GP-1 0 miles. You now have the chance to move even closer to the former world of two-stroke MotoGP with this last release of he 2004 Aprilia GP-1, the final version of the famous RS 250 GP replica motorcycle. This bike is sporting official Colin Edwards and Nori Haga team decals, the colors and graphics add to the bike that represents GP racing at its finest.

The unique look of the 2004 RS250 is dominated by its wrap-around fairing, designed and tested in a wind tunnel. The front mudguard blends perfectly with the fairing, and enhances the Aprilia RS 250's streamlined looks, the characteristic aerodynamic tail completes the Aprilia RS 250's racing image.

The bike was only sold in Europe and Australia.   I am the original owner and it has been on display within my home for several years.   The bike has completed it's new vehicle dealer delivery and prep so the bike has been started prior to my purchase and has 0 miles.  The tires are original as is every part on this bike.   It is untitled for the street as it was intended solely for my collection. The CLEAR title stated above applies to Australia only along with Australian Import Approval plate. I do not know about your state's requirements.  I have huge amounts of dealer promotional material for the bike.

In addition, this bike was judged the best European Two-Stroke bike at Motocarrera's famous Two Stroke Extravaganza held in 2005 in Los Angeles, California. This event was the largest gathering of two-stroke vehicles in America when it was held.  The bike was also displayed at the famous Quail Lodge Motorcycle Gathering Carmel, California in May 2016.

This bike is clearly a museum piece: with zero miles, you'd destroy some of the collector value riding it. It'd be highly unlikely you could register this for the street in most places anyway, and if you're looking for a track or race RS250, you'd be better off finding one with some miles and cosmetic wear on it. Bidding is active, and up to $7,100 with four days left on the auction and the reserve unsurprisingly not met.

Everybody Loves a Winner: 1998 Yamaha TZ250 for Sale

1998-yamaha-tz250-r-side

Just so we're clear: this 1998 Yamaha TZ250 is not to be confused with the road-going but also very cool TZR250. The TZ250 was Yamaha's over-the-counter GP machine, a pure race bike. As such, "originality" is a relative thing, and these things have typically evolved over their racing careers with the goal of winning at any cost. This particular TZ250 has obviously been thoroughly developed, as it was the AMA 250 GP Championship winner in 1999...

1998-yamaha-tz250-l-side-naked

Like the later versions of the TZR250, the TZ250 was powered by a liquid-cooled two-stroke v-twin, backed by a six-speed gearbox, with a classic "banana" swingarm out back. The bike was designed to appeal to entry-level racers and is relatively reliable for a pure racing machine, but it will obviously need regular rebuilds and much more maintenance than a roadbike.

1998-yamaha-tz250-airbox

The 1998 TZ250 seen here featured revised plastics, including that tapered tail that looks a bit like the later Aprilia RS250. The new bodywork also featured a sealed airbox and a ram-air intake to feed the updated carburetors, along with a host of minor upgrades to the rest of the bike.

1998-yamaha-tz250-front-wheel

From the original eBay listing: AMA Championship-Winning 1998 Yamaha TZ250 for Sale

You've heard of Barn Finds... Time Capsules...  Museum Liquidations....   well today, have I got one for you! This is THE 1999 AMA 250 GP Championship winning machine as piloted by Chuck Sorensen.  Exactly as it ran, with factory spares to boot!  It was, and possibly is still today- one of the fastest 250s in the country.

I purchased this in early 2003, directly from James Siddall- owner of World Sports Imports.  This was James' trophy bike.  He mentioned that after it crossed the finish line, it went directly to his office to set behind his desk.  The only hands that have touched the motorcycle since purchase were those of Perry Melneciuc -who, if you know him- besides his being a Factory Mechanic for Ducati, Honda, Yamaha, AMA Race Teams- is considered the most correct, fastidious, compulsive Gran Prix mechanic alive.  All that, PLUS he was a World Sports' team member/rider.  Perry went thru it from tip to tail and made certain everything was correct, fresh and set to their true running settings.  (Perry's notes are included in the sale as to what World Sports ran and what it is set for now -including upper/lower, unleaded/leaded, head volume, deck height, squish, carb settings, transmission selections, etc.)
 
After Perry's meticulous go-thru, fluids were drained and it went into storage/display.  Until now....
 
The motorcycle is completely outfitted with very rare and otherwise unobtainable parts.  Almost every single nut, bolt, axle and pivot is either titanium or aluminum.  Forks and shock are the state of the art (for the time) Ohlins.  Expansion chambers/pipes are factory "A" kit titanium.  Wheels, are five spoke Marvics.
 
The spares package is rich and thick:
 
*Complete set of later model Corbin  #1 body work (seat, two lowers, two uppers, tank (un-dented) (left over from the 2000 campaign)
*Extra set of Factory "A" kit steel expansion chambers
*Sprockets (front and rear) and carriers
*Clutch basket (inner, outer) rod, gear, bearings etc
*two cyclinders
*at least three sets of heads (8.1cc, 8.3cc w/ deto sensors, etc)
*2 Ohlins alternate shock springs
*alternate Ohlins fork springs
*throttle sleeve
*Stator/Rotor
*New side cover with new gasket in package
*TEN brand new matched pistons with rings, wristpins, etc.
*4DP-40 CDI (black box)
*one World Sports Imports Team Polo shirt!
*two (matched L/R set of brake rotors)
*19 spark plugs (11 in bag, used, 8 in holder used but entirely serviceable.
*foot pegs, clutch springs, etc
*electrical umbilical cord for exhaust valve setting
*spare battery, charger
*the SEVENTY-FIVE (not including the ones in the motorcycle) individual gears/alternate ratios that make up the UNOBTAINABLE FACTORY RACING TRANSMISSION KIT.
*tire warmers, f/r stands
*etc.
 
To further document things, the photos should take over from here.  I tried to photograph all the spares so you can paw thru them...  but one photo got missed -showing the two alternate rate Ohlins shock springs. The only thing that has happened to the bike in the years on display is the right aluminum clip-on split due fatigue/time under load.  (You can actually see it in photo #6, right clip on...  a small white line, about 3/4").
 
Outside of that- the motorcycles' internals are fresh and as set by Perry.  With fluids, tires, battery and a proper set up for you- the bike is ready to ride.
1998-yamaha-tz250-expansion-chamber
There are no takers yet at the $17,500 starting bid. The listing includes a huge amount of spares as described by the seller, something that can make or break the deal on a bike like this, unless you're just planning to simply display it. Two-strokes, especially highly-strung, tuned-to-within-an-inch-of-their-lives racing two-strokes consume parts regularly. Folks racing on a budget are likely familiar with that and comfortable wrenching but, when you're running a nearly twenty-year-old, limited-production motorcycle with parts you likely could never have simply picked up on the shelves of your local dealer, the chances of finding what you need are vanishingly small.
1998-yamaha-tz250-dash
And not only are maintenance parts included, but go-fast bits are in the mix. I can't imagine there's a track in the world you couldn't configure those seventy-five gears to tackle, which is probably the whole point, and I have no idea what the trick front end and shock would be worth on the open market. $17,500+ is a lot of money, but considering the race-winning history and the fact that it's basically a complete race-bike kit in a box (just add rider) that suddenly starts to seem pretty reasonable.
