Kawasaki Ninja 400 – Street Born – Track Inspired

The Kawasaki Ninja 400 uses a 399cc twin cylinder engine that packs a punch of 45bhp. Using a new down draft intake which is accompanied by a larger airbox offers increased intake efficiency.

The new Ninja 400 uses an Assist & Slipper clutch This requires much less pressure at the lever making city riding a much easier experience also giving a lot more control on the down change preventing the possibility of the rear wheel locking up.

The Ninja 400 offers considerable weight savings over the outgoing Ninja 300 thanks to its new chassis, suspension and engine, which is 1kg lighter than the Ninja 250). These components also offer improved stability and manoeuvrability.

With the latest ABS unit from Nissin, clamping down on a 290 mm semi-floating disc, the Ninja 400 will stop as well as it goes.

Seat height of just 786mm makes the Kawasaki Ninja 400 very accessible to most riders, there is also an ErGO-FIT higher seat (+30mm) for the taller rider.

LED headlights clearly light up the path of the Ninja 400 whilst adding to the very modern look of this light weight superbike. The speedo assembly is taken from the Ninja 400's big brother the Ninja 650.

The Ninja 400 is also fitted with a 14-litre fuel tank that is capable of offering over 200 miles of range.

The styling of the Kawasaki Ninja 400 is undeniably "Ninja", with aggressive looking headlamps and nose cowl and minimalist rear seat unit. The bike shares so many of its looks with the ZX10R. Extra "volume" has been designed into the bodywork to give this lightweight machine the presence of one much larger.

The big bike looks make this a really credible step into the Kawasaki brand. The handling and performance of the Kawasaki Ninja 400 will keep you interested for years to come.


ERGO-FIT is an interface system that allows a wide range of riders to feel at one with their machine.


ABS (Anti-lock Brake System) ensures stable braking performance by preventing wheel lock during braking.

Based on racing technology, the Assist & Slipper Clutch acts as both a back-torque limiter and a self-servo mechanism that enables a lighter clutch lever pull.
