The Ninja 400 delivers great performance for a range of riders. The engine and chassis have superb power and are lightweight. Like the Ninja 300 that preceded it, this Ninja 400 model possesses much more than high performance. The Ninja 400 takes the winning formula that drove the success of the Ninja 250R and its successors, and amplifies it. Excitement and ease of riding for a wide range of customers – the Ninja 400 is Australia’s favourite learner sports bike.
ENGINE
The Ninja 400 399 cm³ engine delivers a balance of performance and control. The new engine offers performance at all rpm, with good power feeling. Smooth, predictable response contributes to an easy-to-control engine character. Simplified exhaust system traces a straighter line, contributing to lower weight. Pipe wall thickness of 0.8 mm further contributes to weight savings. The exhaust design features 28.6 mm diameter headers with a connecting pipe enhancing the mid range torque. The stylish muffler provides a high grade appearance.
Supersport style downdraft intake provides a shorter, more direct path for intake air to enter the cylinder, improving cylinder filling efficiency and contributing to increased engine power, especially at high rpm. (The downdraft intake also contributes to chassis layout by freeing up space under the seat, facilitating a design that offers an easy reach to the ground. Assist & Slipper Clutch (ø139 mm >> ø125 mm) with less rigid operating plates offers a light lever pull. The clutch has a wider engagement range.
SUSPENSION AND BRAKES
Large 310 mm semi-floating petal front disc (effective diameter: ø286 mm) is gripped by a balanced actuation dual-piston caliper. The disc – the largest in its class – is the same size as the ones used on the Ninja ZX-14R. A more rigid 41 mm telescopic fork (previously ø37 mm) delivers better suspension action. The front wheel feels really planted, direction changes are made easily (even when the bike is fairly upright – handy when navigating traffic jams), and overall the suspension offers the plushness of a larger model.
FRAME
Relaxed rider triangle accommodates a wide range of rider sizes and riding situations. The handle position and slightly forward footpeg position put the rider in a position to control the bike and be comfortable. Radial tyres on the Ninja 400 have excellent grip, agile handling and ride comfort. The 150 mm rear tyre looks like a big bike. Stylish star-pattern 5-spoke wheels. Optimised lateral rigidity benefits handling and provides cornering stability. The wheels are a product of technology gained in racing.
Head-turning looks have always been a forte of Ninja models. The new Ninja 400 boasts futuristic Ninja styling inspired by the mighty Ninja H2. The large-volume bodywork attracts attention, and gives the impression of a larger machine. Slim dual LED headlamps (each featuring low and high beams, as well as a LED position lamp) are highly visible and offer significant brightness. Chin spoilers at the bottom of the front cowl were inspired by the Ninja H2 and Ninja ZX-10R.
