In Japan, the SRX was sold with a reduced displacement of 400 cc for tax reasons, or 608 cc. Also, these models featured an oil cooler. From 1988, the 2NX model was sold, which featured a 17-inch front wheel and single 320 mm brake disc. There was also an SRX250 on the Japanese market, although this differed somewhat in the presence of a headlight fairing and electric start.
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 XT600E, equipped with an electrical starter. Also, the classic twin-shock configuration was dropped for a mono shock design. This iteration was produced until 1997, when production altogether ceased. The SRX was outlived by its predecessor - the SR400 was still available in 2015.Yamaha's SR400 2010 model press release

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. In the USA, the SRX was officially sold only in 1986; in Germany, sales continued until 1990; while in Japan the model was produced up until 1997.
