AGGRESSIVE YET CHIC
Reflecting its sporty personality, the Ninja 400R blends an aggressive Ninja image with the fashion sense and chic sophistication of a modern street bike. Dressed in elegant full-fairing bodywork and with a high attention to the smallest details, it offers the same build quality and finish found on its larger sibling, the Ninja 650R.
Bodywork
* Dual headlamp design features twin position lamps – just like on our Ninja supersport models. The designed shape of the multi-reflector headlamp’s bulb hoods is an example of to the attention given to detail on this model.
* Windscreen set at a sharp angle contributes to the supersport image. A lip at the top of the screen helps to deflect air away from the rider. A duct in the centre of the cowling creates an “air curtain” which reduces wind buffeting at higher speeds and improves rider comfort.
* Tall fuel tank – especially noticeable when viewed from the side – adds to the bike’s crouching appearance. Sharp-edged line motif adds to the bike’s avant-garde design. Flush-surface fuel cap contributes to the sleek lines.
* Side view of the front cowling and fairings (especially the top corners at the front) have distinctive Ninja design elements.
* Supersport-style mirror design is similar to that on the Ninja ZX-6R.
* Fairing design judiciously combines coloured and black panels to create a compact appearance – an approach similar to that used on the Ninja ZX-10R.
* Front turn signals are integral with the fairings, contributing to the bike’s supersport styling.
* Viewed from the rear or from the side, the tail cowl and seat’s sharp design is evident. Thin LED tail lamp and rear turn signals reinforce this image.
* Two-tone design of the front fender contributes to the light, compact appearance.
* An inner fender helps keep the underside of the tail cowl clean and contributes to the Ninja 400R’s sporty look.
* License plate bulb housing and slim rear mud flap add to the sharp image of the tail.
Frame/Rear Suspension
* The frame is a key component of the Ninja 400R’s identity. Like on its larger sibling, the bike’s bodywork accentuates the frame, rather than hiding it.
* The design of the frame, rear suspension and swingarm create an integrated line running from the steering head to the rear hub.
* A trellis frame of high-tensile steel gives the bike a lightweight appearance. 3D analysis was used to achieve the target rigidity and stress values.
* Offset laydown rear single-shock suspension flows smoothly from the frame to the swingarm.
* The braced steel swingarm follows the lines of the frame and rear shock, its triangulated design contributing to the machine’s innovative styling.
* The pipe-like design of the swingarm and stabiliser (thanks to a D-shaped cross-section) contribute to the Ninja 400R’s high-quality appearance.
* Elegant design of the one-piece rider/passenger footpeg stays complements the swingarm and stabiliser.
* Clean finish at the frame joints contributes to the overall quality of the bike.
Instrumentation
* Flowing lines are also evident in the design of the MotoGP-inspired multi-function instrumentation. Features include a fuel gauge, digital speedometer, clock, odometer, dual trip meters and a bar-style digital tachometer. The layout allows the clock and trip meter to be viewed simultaneously. Red backlighting for the LCD screen adds to the sporty image.
* Panelling around the instrument panel gives the inside of the front cowl a clean, finished appearance.
Engine
* The attractively bent exhaust pipes and under-engine muffler arrangement contribute to the Ninja 400R’s attractive styling.
* Under-engine muffler contributes to the bike’s “concentrated” and highly focused appearance.
Brakes/Wheels/Tires
* Triple petal disc brakes contribute to the bike’s sporty image.
* Attractive 6-spoke supersport-style wheels give the bike a light look while reducing unsprung weight.
SPORTY STREET PERFORMANCE
Like its larger Ninja 650R sibling, the Ninja 400R balances compact size and good power. Its combination of a fun, rider-friendly engine character and light, nimble handling results in a package that is highly accessible to new riders while offering enough exciting, sporty performance to keep more experienced riders entertained.
Engine Performance
* Liquid-cooled, DOHC, 8-valve 399 cc Parallel Twin with fuel injection delivers smooth, responsive performance, especially in the low and medium rpm ranges. The engine was tuned for fun, rider-friendly power characteristics that will inspire confidence in new riders.
* The engine’s excellent mid-range power characteristics make the bike especially fun to ride at medium speeds on city streets. Roll-on response is exceptional, offering impressive passing performance.
* 34 mm throttle bodies feature sub-throttles for high power output with smooth, sensitive throttle response.
* Bore and stroke measure 68.4 mm and 54.3 mm – their measurements selected to offer the most exciting performance for a 400cc engine.
* The quick-revving engine offers smooth, linear power delivery. Difficult to stall and with rider-friendly off-idle characteristics, the engine has a highly accessible character.
