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.
Compact Engine Design
* The key to the Ninja 400R’s compact size is its amazingly compact Parallel
Twin engine, which permits the use of a narrow, lightweight frame. The
engine is loaded with innovative technology that enabled the realisation of
its compact design and surprising performance.
- Triangular layout of the crankshaft and transmission shafts makes the
engine very short front-to-back.
- Transmission input shaft, output shaft and change drum are contained in a
“cassette”-style package that both allows a compact layout and facilitates
transmission maintenance chores.
- Semi-dry sump design reduces engine height.
- Plated, linerless aluminium cylinder is lightweight.
- Under-engine muffler improves mass centralisation and lowers the bike’s
centre of gravity.
* Together with the compact engine, the frame’s elegant design realises a
package that is slim, low, lightweight and compact.
- The compact engine allows use of a slim, minimalist frame, resulting in a
design that is narrow at the knees and feet.
- The compact engine also allows an extremely short wheelbase, giving light
and nimble handling.
- Because a long swingarm can be used, rear suspension action and handling
are both improved.
- 3D analysis was used to achieve the ideal stiffness balance for the frame,
contributing to the superb handling characteristics.
- The frame is constructed of high-tensile steel, giving it a lightness
rivalling that of aluminium frames.
- The layout of the offset single-shock rear suspension allows the battery
to be located beside the shock instead of above it. This elegant arrangement
allows a lower seat height as well as a slim design.
* The same characteristics that make it fun to ride (responsive handling and
rider-friendly ergonomics), also make the Ninja 400R ideal for new riders.
* A short wheelbase and tight turning radius contribute to the Ninja 400R’s
high manoeuvrability.
Light Handling
* Frame and swingarm rigidity balance chosen to offer light, rider-friendly
handling.
* Front and rear suspension settings match frame and swingarm
characteristics , and contribute to the light, rider-friendly handling.
Minimal Vibration
* Rubber mounts instead of rigid mounts used for the upper-rear engine
mounts reduce vibration transmitted to the rider through the seat.
* Handlebar is rubber-mounted to reduce vibration transmitted through the
handle grips.
* Rider and pillion footpegs are rubber coated to further reduce vibration.
* Low vibration levels ensure that riders do not get fatigued after long
rides.
Rider-friendly Ergonomics
* The riding position was specially designed to inspire rider confidence. An
ideal relationship between the handlebars, seat and footpegs results in a
comfortable and natural position suitable for a wide range of riders.
* The narrow frame and engine make for an overall narrow package, allowing
the rider to keep his or her knees and feet close together.
* Thanks to the low seat height and slim overall design, it’s easy to keep
both feet firmly on the ground when stopped, an important consideration for
many riders.
Brakes
* Dual 300 mm front petal disc brakes and 220 mm rear petal disc look great
and deliver plenty of braking power.
* Twin-piston front brake calipers features 27 mm pistons. Front brake
master cylinder has a 14 mm piston.
