Model History:

The SR500 was marketed in Asia and Oceania (1978–1999), North America (1978–1981); and Europe (1978–1983), and was not marketed in the Japanese market.
The SR was originally developed under the design credo "easy to use", and when Yamaha's Technical Director wrenched his ankle while testing a prototype, easier starting became a priority—and Yamaha developed a decompression lever and sight glass system.
The SR was styled by Atsushi Ishiyama with Yamaha presenting a pre-production prototype to US dealers in late 1975. Ishiyama said of the bike's styling: "Our choice was to design the new SR500 with a strong family image and a strong link to our first four stroke, the XS 650 twin, which was also inspired by British design.
The 1978–1979 US version of the SR500 had front and rear disc brakes while the 1980–1981 models had a front disc and rear drum brake, while the European 78–79 models had spoked wheels, front disc and rear drum brake. Cast aluminum wheels on US models (rear disk brake) for 78-79 were not tubeless applicable while (drum brake) for 80-81 were stamped tubeless applicable and so equipped. By the end of 1981, the SR500 was discontinued in the US market, while continuing in Europe and Japan. The model ended production in 1999.
The SR500 employed a slightly modified version of its large single-cylinder from the XT500/TT500 and had electronic ignition as well as a handle bar mounted compression release lever to make kick starting much easier.
