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.

Assist & Slipper Clutch

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.

Economical Riding Indicator

The Economical Riding Indicator is a mark appearing on the instrument panel to indicate favourable fuel consumption, encouraging fuel efficient riding


A new benchmark

Featherweight class, heavyweight punch.

A replacement for the Kawasaki Ninja 300, the new Ninja 400 features a host of improvements that make the bike a leader in its class. A featherweight tubular chassis uses the engine as a stress member, adding to the rigidity while saving tremendous amounts of weight, at only 168kg wet this motorcycle is a true featherweight, in fact it is 1kg lighter than its predecessor. On the other hand it does increase the capacity of the engine from the 300 to 400cc adding respectable 6bhp (From 38 to 44) and very impressive 11nm of torque (From 27 to 38). Making the Z400 a fantastic and endlessly fun package.


Track Inspired

Undeniable Ninja heritage.

Kawasaki proudly introduces a new sport model into this highly competitive arena. Clad in sharp Ninja styling, the Ninja 400 delivers greater performance than its predecessor care of all-new engine and chassis that are more powerful and significantly lighter. But like the Ninja 300 that preceded it, this new Ninja model possesses much more than high performance. Not only does the Ninja 400 offer stunning, high-quality looks, its stronger engine performance, light, predictable handling and relaxed, sporty riding position make it both fun and easy to ride.


The Ninja Philosophy

Beauty in technology.

The Ninja design philosophy is strongly utilised throughout the bike. Unmistakable stance of the bike that brings to mind the mighty Ninja H2 and the excellent Ninja ZX6R 636. In addition, in line with the rest of the Ninja motorcycles, sharp lines of the fairings are complemented by stunning KRT livery on display for those who truly appreciate the beauty that comes from Kawasaki mechanical excellence.


Unmistakable heartbeat

Legendary Kawasaki twin cylinder engine.

The noise of a 90 degree crank, twin cylinder, dual overhead cam, four stroke Kawasaki engine is unmistakable to all enthusiasts of motorcycling. Tried, tested and loved by many powerplant is at the centre of the new bike design. Increased performance comes from extra 100cc of engine capacity which allows the bike to pass through the rigorous Euro4 emissions limits while at the same time boosting the mid and low end performance significantly. Making for smoother and more usable power delivery.
