YAMAHA SR 400 (2010-2011) Specs, Performance & Photos

In 2011, the Japanese maker launched the Yamaha SR400, a standard machine manufactured by Yamaha from 1978 to 2012. The bike was part of the SR series in Yamaha's range and was delivered as a street version of the Yamaha XT500 model.

The last upgrade was in 2010 when the bike was fitted with a new fuel injection system for a more responsive throttle response, a new exhaust system with a new catalyzer to comply with tighter emission standards, and a larger oxygen sensor.

From the factory, the bike came with standard features, such as a round headlight with a chromed housing, a front steel fender, a teardrop-shaped fuel tank, a one-piece dual seat with a passenger grab rail, a chromed exhaust system, and wire-spoke wheels with lightweight rims.

The 2011 Yamaha SR400 took its power from a 399cc four-stroke single-cylinder air-cooled engine fed by an electronically controlled fuel injection system, boasting 23 hp with a maximum peak at 6,500 rpm and 27 Nm (20 lb-ft) torque at 3,000 rpm.

The bike was built on a double-cradle steel frame, fitted on the front with a telescopic fork with 150 mm wheel travel and dual side-mounted shock absorbers on the rear, delivering optimum handling performance.

The braking performance was achieved by a 298 mm disc mounted on the front wheel with a hydraulic caliper and a drum braking unit on the rear, offering solid and reliable stopping power.
