In 2016, Yamaha released the SR 400, a standard motorcycle manufactured by the Japanese maker from 1978 to 2021. The bike debuted in 1978 as a street version of the Yamaha XT500, with a classic riding position and styling designs resembling the UJM of the 1970s.
Alongside the Yamaha SR 400, the Japanese maker sold the Yamaha SR 500, a similar machine with a more significant engine displacement achieved with a different crankshaft and a longer piston stroke.
The 2016 Yamaha SR 400 was fitted with standard features right from the factory, including a large round headlight with a chromed housing, a teardrop-shaped fuel tank, a single-piece dual seat with a passenger grab rail, a chromed exhaust system, and wire-spoke wheels with lightweight aluminum rims.
The bike had a double-cradle steel frame with a telescopic fork mounted on the front, offering 150 mm wheel travel and dual side-mounted shock absorbers with 104 mm wheel travel, delivering optimum suspension performance and handling.
The braking power was achieved by a 298 mm disc with a hydraulic caliper on the front wheel and a drum braking unit on the rear, delivering optimum stopping power.
As for power, the 2016 Yamaha SR 400 had a 399cc four-stroke single-cylinder air-cooled engine with an electronically controlled fuel injection system, boasting 23 hp at 6,500 rpm and 27 Nm (20 lb-ft) torque at 3,000 rpm.
