Get Your GP On: 1985 Yamaha RZ500

Hot on the heels of the big Gamma we posted earlier this week, it only seemed fair to post the other 500cc competition – the Yamaha RZ500. Seeming more readily available than the Gamma, the RZ500 is another of the GP replica two strokes that were never officially imported into the United States. Today these smokers bring big bucks when presented in decent condition, and it’s easy to see why: Rare, fast and very exclusive, the Yamaha RZ500 was the closest you could come to channeling your inner Roberts, Lawson or Rainey on the street. And who didn’t want to do that?? Today, 35+ years removed, the world of ever-tightening emission and noise restrictions make these screaming banshees icons of a past era, never to be seen again. But today’s example shows that these icons can live on in the used bike market.

Unlike Suzuki’s square four arrangement, Yamaha lined up their GP replica in a 50 degree, V-4 formation. Both brands utilized a twin crank setup – more out of two-stroke necessity than anything else. That meant that this is actually two twin-cylinder engines powering the bike, rather than one bigger four banger. Power from the two engines is harnessed and consolidated in the clutch & gearbox areas, making the whole thing seamless to the rider. The rest is pure two stroke wizardry, with reed valves, exhaust power valves and four individual tuned-length pipes for maximum HP (approaching 90 HP when new and stock). The chassis is a rather pedestrian mild steel affair. The Japanese home market offered a power-restricted version with alloy frame – the RZV – which shaved about 20 pounds off the total dry weight – but those are even more rare than the rest of the world model we see here. The swing arm for both models is aluminum. As per the fad of the times, the front hoop is a mere 16″ to reduce the gyroscopic effect and speed up transitions.

From the seller:
Also known as the Race-Developed 500cc Liquid-Cooled motorcycle or RD500LC, the RZ500 was produced in limited numbers from 1984-85 as a road legal production version of the YZR500 2-stroke V-4 Grand Prix factory racer. This rarely seen replica racer was not sold in the United States, and the1985 RZ500 stands as one of the most collectible road-going motorcycles of its era.

Very rare V4
Light and powerful
2 stroke Sports Bike
Liquid cooled, 6 speed
High performance with speed of 148 mph
499 cc
Odometer: 26604 km (16530 miles)

Bike is all stock and original, with the exception of the upgraded exhaust system (stock exhaust system will be included with the bike purchase). Original paint; see picture for a few minor flaws.

Bike is in excellent running condition with everything working.

Given the rarity of these bikes in the US and considering the short life span they had in market when new (model years spanned 1984 – 1986), it should be no surprise that prices on these big smokers are wafting up like the blue smoke they create. Still, these are a pretty good bet for long-term value appreciation since they are popular, approachable, and in limited supply. I don’t see any of those factors changing in the foreseeable future, although the availability of spares might become an issue at some point.

Today’s bike looks pretty good for an older girl (even with low-res photos). There are some unfortunate nicks and cracks in the plastics, but everything appears to be in place. The JL exhaust out of the UK is a nice addition, and the seller notes that the stock pipes come with. Definitely a bonus for the collector. The red handgrips look to be aftermarket, but the rest comes across as an honest example of the breed. With 16,530 miles on the clock this is not a garage queen, so somebody please buy it and get out there and ride! Check out all of the details here, and Good Luck!!

  • Growing up in the UK, I always enjoyed the sight and sound of the 2 stroke replicas screaming by with wailing expansion chambers, popping wheelies on the power band. However, my memories are all of 250s and 350s. These bigger strikers didn’t seem to cash in on the bug.
