The Yamaha SRX was a motorcycle manufactured from 1985 until 1997 by the Yamaha Motor Corporation.

In an attempt to repeat the success of the SR 500, Yamaha placed a more modern engine derived from the XT 600 into a light, sportive 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 SRX 600 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 not much more money. 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.

[edit] Japanese models

In Japan, the SRX was sold with a reduced displacement of 400 ccm for tax reasons. Also, these models featured an extra oil cooler, but apparently only a single front disc brake. There was also an SRX 250 on the Japanese market, which seems to be a design not so closely related to the 400 and 600 models.

When the international marketing of the SRX stopped, in Japan there was a new production line 3VN; it received an engine derived from the newer XT 600 E, equipped with an electrical starter. Also, the classical twin-shock configuration was dropped for a mono shock design. This bike was produced until 1997, when production ceased. The SRX was outlived by its predecessor - the SR 400 is sold until 2008.
