Triumph Bonneville 400

The upcoming Triumph Bonneville 400 is a new retro-styled motorcycle. Recent test mules suggest that it will feature a larger, more rounded fuel tank, rounded side panels, chunkier front and rear fenders for better road presence. Compared to the Speed 400, Triumph Bonneville 400 will be noticeably larger. It will also feature a flat bench-style seat, conventional telescopic fork and twin rear shock absorbers, giving it a more traditional Bonneville-inspired design. It is expected to use the 349cc, single-cylinder, liquid-cooled engine that is also seen in the Speed T4. The motorcycle is expected to be positioned as a more classic alternative to the Speed 400.
