The Yamaha SRX is a motorcycle that was manufactured from 1985 to 1997 by the Yamaha Motor Company. In an attempt to repeat the success of the SR500, Yamaha placed a more modern engine derived from the XT600 into a light, sporty street bike. While still being an air-cooled, overhead-camshaft single-cylinder like its predecessor, the new engine featured a four-valved cylinder head, a two-staged carburetor, a balance shaft, and various improvements. The chassis was a lightweight steel frame with alloy wheels, a double disc brake on the front- and a single disc brake on the rear wheel.

However, unlike its cheaper predecessor, the SRX600 did not compete well on the international market. Nimble handling, light weight, and unique styling did not compete well with the heavier, faster multi-cylinder bikes available for a similar price. Still, Yamaha claims to have sold 19,000 units of the SRX.[1] In the USA, the SRX was officially sold only in 1986; in Germany, sales continued until 1990
