SR400

The big single has always held a special place in the hearts of motorcyclists. And when we launched the original Yamaha SR400 over 30 years ago it became a favourite with riders who yearned for a simple, agile and engaging motorcycle.

FEATURES

Retro style with authentic design

Unlike some retro bikes that are modern interpretations of older designs, the SR400 is an authentic living classic which has been constructed to virtually the same specification as the original model. With its air-cooled engine and twin-shock chassis, this timeless big single represents a return to motorcycling’s core values.

Plush front forks and twin shock rear suspension

The SR400 is equipped with traditional suspension that gives a plush and comfortable ride, with the front forks giving 150 mm travel and the twin shocks at the rear giving 110 mm wheel movement. And with its slim fuel tank, raised handlebars and long dual seat, the SR400 benefits from a natural and relaxed riding position

Decompressor and piston position indicator for easy kick starting

To underline our commitment to originality the SR400 is equipped with a kick starter as the only means of getting the engine running. Starting is made easier by the decompressor lever on the handlebars and a piston position indicator on the side of the cylinder head, as well as the new fuel injection system
