The Suzuki RG500 "Gamma", a sport bike with a two-stroke engine, was produced by Suzuki for just two years between 1985 and 1987.
The RG "Gamma" 500 was directly based on the series of Suzuki RG Γ 500 Grand Prix motorcycles with almost identical features to the official two-stroke machines used by Italian world champion Franco Uncini during the 1984 season with the Gallina team. The RG Γ 500 won two consecutive Riders' Championships in the 500 cc class with Marco Lucchinelli in 1981 and Franco Uncini in 1982. Like its GP forebears, the road-going RG was powered by a naturally aspirated, rotary-valve inducted, twin crank square four two-stroke engine displacing some 498 cc. This engine employed thermostatically controlled liquid-cooling by means of a front-mounted radiator.
Suzuki used an aluminum box-section frame with castings for the headstock and rear swing arm. The front suspension had pre-load adjust, as well as an anti-dive system called Posi Damp. This was a popular feature on early 1980s sports bikes and was supposed to control the tendency of a motorcycle's nose to dive under braking. At the rear, the full-floater suspension design used dual swing arms.
