Powerful, Rider-Friendly Parallel Twin
The engine offers increased performance at all rpm compared to its predecessor, with good power feeling. Smooth, predictable response contributes to an easy-to-control engine character.
Compact, Lightweight & Efficient
A clean design trimmed of any unnecessary items, and a revamped layout enable a slim engine and a cooling system with minimised external piping.
New Assist & Slipper Clutch
More compact clutch (φ139 mm >> φ125 mm) with less rigid operating plates offers a 20% lighter lever pull. Complementing the extremely light feel at the lever, the clutch has a wider engagement range, facilitating control.
Lightweight Trellis Frame
The Ninja 400 features a trellis frame similar in design to that of the Ninja H2. Kawasaki’s advanced dynamic rigidity analysis was used to ensure optimum rigidity with light weight. The engine is rigid-mounted and used as a stressed member. The frame design contributes significantly to the bike’s low curb mass.
