The Yamaha SR 400 was a standard motorcycle part of the SR series in Yamaha's range, manufactured from 1978 to 2021 as a street version of the Yamaha XT500 model. The bike resembled the Universal Japanese Motorcycle of the 1970s and featured a standard riding position.
In 2002, the Japanese motorcycle manufacturer launched the Yamaha SR 400, a standard motorcycle with no significant modifications over its production period. The bike featured a kick-starter with a sight glass on the right side of the cylinder and a decompressor lever on the left side of the handlebar.
The bike came from the factory with standard features, such as a one-piece dual seat, a black-finished frame, a teardrop-shaped fuel tank, a chromed exhaust system, a round headlight with a chromed housing, and lightweight wire-spoke wheels.
In the performance department, the 2002 Yamaha SR 400 packed a 399cc four-stroke single-cylinder air-cooled engine fed by a single carburetor, delivering an output power of 23 hp with a peak force at 6,500 rpm and 27 Nm (20 lb-ft) torque at 3,000 rpm.
The bike's suspension system was handled by a telescopic fork on the front with 150 mm wheel travel and dual side-mounted shock absorbers on the rear with 111 mm wheel travel, offering optimum suspension performance and handling.
In the braking department, the 2002 Yamaha SR 400 was fitted with a single disc, a hydraulic caliper on the front wheel, and a drum braking unit on the rear, delivering strong stopping power.
