Kawasaki has a new Ninja 400 on deck for the 2018 model year, releasing details of the machine during this year’s Tokyo Motor Show.
The liquid-cooled Parallel Twin is 399cc and was designed from the ground up according to the Green brand. Weight and space saving measures topped the list of objectives during engine design and Kawasaki claims the finished product is comparable in size to the 2013-2017 Ninja 250. This new engine pumps out a claimed 44.7 horsepower and 28 lb-ft of torque. It’s got a larger airbox compared to the Ninja 300, with revised intake funnels, to better utilize incoming air, particularly at high rpm.
As for weight savings, Kawasaki was able to eliminate sub-throttles, optimize the cooling system, develop a more compact assist and slipper clutch, utilize thinner walls for the exhaust system, use forged cam shafts and lower the volume of oil required by the motorcycle.
There is a new radiator fan cover also, intended to direct heat away from the rider more effectively.
For the chassis, Kawasaki looked to its larger sports bikes for direction. The 400 comes with a trellis frame that uses the engine as a stressed member, similar in design to the H2. It’s wheelbase is shorter than the Ninja 300, and a new die-cast aluminum swingarm mounting plate simplifies construction. The total package weighs less than the Ninja 300, which is listed at 383.7-pounds, with an indicated 370-pound curb weight.
The 41mm fork is more rigid than the outgoing 37mm set-up, and a steeper rake (24.7 degrees compared to 27 degrees on the 300) makes for a more nimble motorcycle. Out back is a five-way preload adjustable shock.
Kawasaki fit a larger 310mm, semi-floating petal front brake disc and updated master cylinder to the 400. The rear 220mm disc and dual piston caliper set-up out back mimics the design currently utilized. A Nissin ABS-equipped model will be available as an option also.
The five-spoke wheels are new, and bodywork is revised to give the 400 look more akin to its larger siblings. The fuel tank is slimmed and fuel capacity reduced to 3.6 gallons (down from 4.5), helping to make the cockpit more compact and contribute to weight savings. The seat is made from thicker padding also for additional comfort.
It’s got the same instrument cluster found on the Ninja 650 along with LED head and taillights.
Available accessories will include a larger windscreen, DC outlet, ERGO-FIT high seat, tank pad, tank bag, pillion seat cover, frame sliders and helmet lock among others.
There is no pricing or availability information available yet for the Ninja 400, so stay tuned.
