Sorted: 1986 Yamaha RZ500 for Sale

Compared to a modern superbike, the fire-breathing performance of vintage two-stroke race replicas maybe isn’t quite as wild as their reputation would suggest. At the time, they were light and very powerful, but weren’t exactly at Grand Prix extremes of either even then. Modern machines have levels of rigidity, suspension response, and electronic assistance an old smoker like this Yamaha RZ500 could only dream of, back in the hazy 1980s. But an RZ500 still has the goods to be hustled along a canyon road, and this example has had a couple of updates to the running gear to help it hang with newer bikes.

Also known as the RD500LC in Europe and the RZV500R in Japan, the RZ500 was powered by a a liquid-cooled 50° two-stroke V4 that featured twin cranks, a pair of YPVS power valves, a balance shaft to smooth things out, and magnesium components to reduce weight. Lubrication for the two-stroke was handled by Yamaha’s Autolube oil-injection and the transmission had six speeds. At the front was a 16″ wheel and a set of anti-dive forks matched to an underslung rear shock and an 18″ hoop out back, limiting a modern rider’s access to good performance rubber.

The Yamaha RZ500 made a claimed 88hp and weighed in at 436lbs wet, while a 1986 Suzuki GSX-R750 of the same period made a claimed 106hp and weighed 465lbs wet, so performance was pretty similar on paper. However, the character of the two bikes couldn’t be more different. With heavy two-stroke smoke dripping out of the four exhaust tips and the crackle and zing of the engine, you have to work the RZ500 much harder, in spite of a pair of power valves designed to improve midrange response.

Interestingly, the Japanese market bikes received an aluminum frame to offset the reduction in power required by government restrictions. I always wonder why, since this was a premium sportbike to begin with, they didn’t just fit the aluminum frames to all of them. Certainly, if you wanted to build your dream RZ500 and throw originality to the wind, that’s what you’d probably do. This particular bike follows the path of “thoughtful evolution” and includes some components from later machines that should help the bike’s cornering prowess.

It’s maybe not a purist’s museum piece, with the later YZF750 front end and 17″ wheels. But, while the RZ500 was commendably light and agile by mid-80s standards, an update to the fork and brakes should help bring the bike closer to modern feel, while the ZX6 wheels will make tire choice much simpler, and give the new owner access to modern levels of grip.

From the original eBay listing: 1986 Yamaha RZ500 for Sale

We are a Yamaha dealer selling this bike for a 2 stroke collector’s estate. This is a great example of a 1986 Yamaha RZ500. It has a clear Pennsylvania title (has been here since at least 2006) but was originally sold in Canada. VIN is JYA52X007GA007150. The odometer reads 73 miles but since the KM speedo was replaced the actual odometer is aprox. 7500 km with about 1000 km since rebuild.

Cosmetic condition as you can see in the pics is excellent. Bodywork is all OEM including solo cowl. We’ve included a owner’s manual and service manual – all in good shape. There is 1 original factory key and 1 copy. Frame up restoration done in 2006. At that time, all seals were replaced, cylinders honed (std bore)

We’ve had our resident two-stroke tech go through the bike after a short storage. Air cleaner was replaced, tank drained, carbs removed and thoroughly cleaned, etc. Plugs replaced, fresh trans oil. Bike started easily and runs well with no clutch slippage. Left fork seal has slight seep and as any two stroke, it could take more fussing to get carburation perfect. Trans shifts very well but clutch pull a bit heavy (upgraded springs?). Brakes solid and chatter free. This is a well sorted RZ.

Upgrades and mods include but are not limited to:

  • YZF750 complete USD front end and brakes.
  • JMC custom polished swingarm
  • Penske remote reservoir rear shock
  • Alex Mayes chambers – Rare!
  • Carbon Tech low tension reeds (porting is stock)
  • ZX6 wheels (both wheels powder coated red)
  • Magnesium left engine cover
  • Braided brake lines
  • Hindsight mirrors
  • MPH speedometer
  • Zero Gravity windscreen
  • Carbon fiber meter panel

There is NO reserve or buy-it-now price on this item

Other RZ brochures and some parts are available but are not included with this bike.

Pick up at our dealership in Pennsylvania (19512) has no charge of course, but delivery by truck or international shipping is the responsibility of the buyer. 

As the seller describes it, “this is a well sorted RZ,” a daily rider that captures the feel of an earlier era of performance, with a couple modern touches. Unfortunately, there are no takers yet at the $13,000 starting bid, with just a few hours left on the auction. Is it too early in the season? Were the modifications just a bridge too far? Has the interest in two-strokes plateaued?

  • In many ways, I believe the old 2 stroke GP class was the pinnacle of bike racing from the prospective of rider ability. No launch control, nasty powerbands, flexible frames, limited tires and no traction control. While current GP class riders are unquestionable skilled, the riders back in the day with limited safety gear had their hands full.

    Respect to Roberts, Schwantz, Rainey for entertaining me all those years.

  • I couldn’t agree more, would love to see the the two strokes back to GP and motocross, I sure miss them as a spectator.

  • It’s unfortunate the seller didn’t realize that this is a very rare bike. This is a 1986 RZ500S. Only 150 were made in 1986 and all went to Canada. The VIN numbers were from 7171 to 7250. The engines in these 1986 RZ500S models had a different upper crank that incorporated an extra flywheel. It was an attempt to smooth vibrations, but there is no indication that it was actually successful at doing so.

    Had this bike been 100% stock, as it was in 1986, and had it been properly advertised, it would have sold for much more than it did. It sold for $15,237 US. The seller is representing an estate, so had no idea what he was actually selling. Lack of knowledge can be expensive. I hope the winning bidder knows the significance of this bike and returns it to it’s original 1986 condition.

    The upper crank requires a different right crank seal than the 1984 and 1985 RZ500/RZV500. This seal has been unavailable for many years, meaning it is nearly impossible to rebuild the engine. There was one solution developed some years ago where an alloy spacer ring is machined for the outer diameter and a lower crank seal is used inside of the spacer. If you don’t know what you’ve bought there will be a lot of head scratching come rebuild time.

    • Agree with jpu: I love the people that chime in here to share bits of very oddball knowledge. Had no idea!

  • JR this is why I really like this site.

  • My apologies…I have a typographical error…the VINs are 7101 to 7250.

  • thats a fair market price for that bike. Its actually a bike you can enjoy and ride with the upgrades it has. I like it, and hope the new owner rides it, lots.

  • I don’t know, I would ride it until it grenaded, and throw another lump in it, and I would bet it would be a long time till it did…
