All-Original GP Machine: 1982 Suzuki RGB500 Mk7 XR40 for Sale
Ridden by such luminaries as Barry Sheene and Randy Mamola, the two-stroke Suzuki RGB500 was eventually developed into the dominant machine you see here, but it went through a significant evolution following its introduction in 1974. As you’d expect, the bike always had power to spare, but high speed handling was suspect at first…
By the time the 1982 bike rolled around, Suzuki had moved to a “square” 54mm x 54mm engine for a grand total of 495cc. It was far more reliable than previous iterations and featured the same stepped cylinders seen on the RG500 Gamma road bike that had the rear pair of cylinders raised up slightly higher than the front pair. With a dry weight of 292lbs and 120hp, the bike could reach speeds of up to 170mph, which is pretty terrifying considering the tire technology of the time.
Fascinating details seen in the photos include the square-four’s complex throttle cable assembly and the anti-dive front system on the front forks.

With a beautiful period paint scheme and tons of rare, race-spec parts, this bike may not have been ridden by any famous racers to any notable victories, but it’s also available at a price much lower than you’d expect to pay for one of those machines. Bidding is just north of $25,000 there’s a ways to go until we hit the $65,000 Buy It Now price. It’s in impressively original condition and would make a stunning collector’s piece, but hopefully, the rise in popularity of vintage racing will see this bike returned to the track.
