Parallel Twin Engine & Transmission
The Z400 features a compact, lightweight, and efficient 399cc liquid-cooled four-stroke parallel twin engine that also powers its Ninja 400 counterpart. The displacement comes by way of the 70.00 mm x 2 / 5 51.8 mm bore & stroke. The high performance of the engine was achieved through careful airbox and intake design, as well as engine internals.
Downdraft intake routing plays a pivotal role in producing performance, especially at high rpms, and a large air box offers intake efficiency. The downdraft intake utilizes the shortest and most direct path for air to enter the cylinder, which helps cylinder-filling efficiency and contributes to engine power. Airbox volume was made as tall as possible to ensure sufficient clearance for the intake funnels at 5.8 liters. The airbox features optimized rigidity at the top of the airbox, which reduces unwanted noise, enabling riders to more clearly hear the engine's intake note when accelerating. Different height on the left and right intake funnels contribute to the engine's smooth response by allowing torque valleys to be tuned out.
To enable smooth and seamless shifting, a close gear ratio was chosen for the transmission, with gears progressing easily from one to the next. Complementing the transmission is a compact assist & slipper clutch, with operating plates that feature optimized rigidity to create a lighter feel at the lever; the clutch has a wide engagement range, facilitating control.
When excessive engine braking occurs as a result of quick or accidental downshifts, the slipper cam comes into play, forcing the clutch hub and operating plate apart, which relieves pressure on the clutch plates to reduce back-torque and help prevent the rear tire from hopping and skidding.
Innovative Kawasaki technology such as the radiator fan cover, which is located behind the radiator, directs hot air out to the sides away from the rider, reducing rider discomfort. Redirecting the hot air also helps keep the tank, frame and other parts that contact the rider cooler. The heat management system was designed using computational fluid dynamics analysis and requires no additional parts to direct airflow inside the engine compartment.
Kawasaki's advanced dynamic rigidity analysis research was utilized
in designing the trellis frame of the Z400 motorcycle to ensure
optimum rigidity and produce nimble, lightweight handling
characteristics. A rigid mounted engine with short mounting
brackets was used as a stressed member in the frame to increase
rigidity. The chassis has a supersport-style design with a
short-wheelbase and long swingarm, which is complemented by a steep
caster angle that delivers sporty natural handling. A short
wheelbase on the new Z400 contributes to easy maneuverability and
the overall wheelbase measurement for the Z400 is 53.9 inches. The
frame & engine design contribute significantly to the bike's low
While it was important to keep the weight down and wheelbase short on the chassis design, it was also crucial to maintain handling characteristics, by adding length to the swingarm. The swingarm and mounting plate design helped contribute to the bike's overall light weight. The die-cast aluminum swingarm mounting plate eliminates the need to add heavy additional cross member pieces to the frame because it bolts to the back of the engine, allowing the pivot shaft to go through the plate and mount the swingarm directly to the engine. Forming the swingarm from square tubing eliminates the need for additional gusseting, while maintaining rigidity and keeping weight to a minimum.
In addition to the engine and frame, other key lightweight contributions came from a slim seat design, wheel design, and heat management system that requires minimal parts. All of these designs helped to create a bike with a curb weight of 368.1 pounds.
Complementing the ride comfort of the trellis frame is a large 41
mm telescopic front fork, which provides riders with superb front
end feel and traction, facilitating direction changes even when the
bike is fairly upright - handy in navigating traffic jams. Thanks
to design of the fork, the need for a front fender brace has been
eliminated, helping save additional weight. A steep caster angle
provides nimble handling feeling, while the optimized linkage
ratios and rear suspension settings contribute to the highquality
ride feel. The shock features five-way preload adjustability, which
allows riders to adjust the stiffness and ride height to suit body
weight or when riding two-up. The shock is easily adjustable with
the on-board tool kit. The overall suspension of the Z400 offers
the plushness found on the larger models in the Z family for
everyday riding comfort.
To enhance handling and performance, the Z400 motorcycle comes
equipped with a largest in class 310 mm semi-floating petal front
disc, which is gripped by a balanced actuation dual-piston caliper.
The front brake master cylinder design helps eliminate ineffective
stroke for increased control. Handling the rear braking duties is a
220 mm petal disc, which is slowed by a dual-piston caliper with
large 27 mm pistons. The front and rear brake hose material and
dimensions were carefully selected to offer excellent brake
feedback. The Z400 ABS features Nissin's latest ABS control
The wheels and tires also follow the same weight savings theme applied throughout the build of the Z400. The stylish and lightweight five-spoke star-pattern wheels offer lateral rigidity and contribute to the bike's stability and lightweight image. The wheel design is a product of technology gained in World Superbike competition. The lightweight radial tires on the Z400 contribute to both agile handling and riding comfort. The 150 mm rear tire imposes an aggressive looking rear end for the newest member of the Z family.
Kawasaki's Z styling is known for providing an aggressive and
premium look that comes to life with an ideal blend of sporty
performance and everyday versatility. The new Z400 boasts the
sharp, aggressive styling similar to that found on the Kawasaki
Z650 and Z900 and leaves a lasting impression for bystanders. A
staple in the Z family, the Sugomi design elements provide a
crouching stance, lowpositioned head, and upswept tail to give the
Z400 motorcycle a silhouette that is instantly recognizable as a
This design of the bodywork on the Z400 enhances the appearance of the engine and exhaust and highlights the functional beauty of the engine, elegantly curved exhaust header pipes, and trellis frame. Sharp design of the front cowl is complemented by a compact, dark meter visor that adds to the aggressive and sporty looks. In addition to the sharp looks is an LED headlamp that offers increased brightness in its wide illuminated path. The aggressive front fender design features holes cut into the sides. The bodywork packs the punch of a much larger machine, which is reinforced by its superb fit and finish. Sharp rear turn signals complement the aggressive Z styling; both front and rear turn signals utilize clear lenses for a high-quality look. A sculpted upswept tail cowl and LED taillight design also contribute to a sharp impression from the rear of the bike. Elegant mirror stays mount the mirrors to the wide, flat handlebars. The bike also features a forward-slant of the compact fuel tank to contribute to its distinct design.
The relaxed rider triangle of the Z400 motorcycle accommodates a
wide array of riders and riding situations. The Z400 features a
relatively upright riding position, wide handlebar, and a more
sporty yet forward footpeg position that allow the rider to control
the bike while also offering rider comfort. The slightly forward
positioning of the sporty aluminum footpegs contributes to direct
feel, good controllability, and a comfortable riding
The design of the bodywork on the Z400 offers ride comfort. The sleek fuel tank design enables good contact with the bike for increased control, all while helping keep weight to a minimum.
The seat height and narrow design make it even easier for riders to get their feet to the ground. A deep seat pan allows for a 90 mm low-rebound urethane seat cushion, offering excellent ride comfort.
Kawasaki engineers placed great emphasis on making sure the cockpit
of the Z400 was clean and easy to read. The stacked instrument
cluster is similar in size to that found on the Z650 model, and
features a new large analog tachometer face, and gear position
indicator at its center. The instrument cluster sits above a
multi-function negative display LCD screen.
The gear position indicator enhances confidence while also contributing to the Z400's sporty image. In addition to the digital speedometer and gear position indicator, display functions include: odometer, dual trip meters, fuel gauge, remaining range, current and average fuel consumption, coolant temperature, clock and the Economical Riding Indicator. The Economical Riding Indicator appears on the LCD screen to indicate favorable fuel consumption, notifying riders when they are operating within the optimal conditions to maximize their fuel efficiency.
