presentation of the Ninja 400 2023
butwhat happened to the 400 Ninja? Kawa's young sportswoman, a native A2 licensee, disappeared from the radar after the 2020 season. Where did it leave its footpegs in the meantime? That's none of our business..... But on the way back, she stopped off at the "engine conformity" workshop to treat herself to a Euro5 badge. Thus revised, the 4-cents can return to the European market.
With the same look. This Ninja receives no touch-ups, apart from updated color schemes. Engine recalibration has made it cleaner, without affecting its maximum power of 45 hp. Only torque is reduced, by just 0.1 mkg. Fans of "sporty firsts" will be delighted to find this big, fun and easy shrew, with its taut, attractive design. The Ninja should be in stores in September 2022, vintage 2023.
The Ninja low-size has asserted itself over time. A long way from the puny Ninja 250 R, grandmother of the current 400. It was in 2018 that the latter settled in, with enough to place it in a category in need of recognition (even if the WSPP 300 inflames riders). Kawasaki had designed a new engine for it with as much care as for its larger-displacement mills. A great deal of work was done on the air intake. An optimized flow and a high-volume airbox (5.8 L) make it easy to rev. The left and right intake cones are of different heights to contribute to a smoother engine response and to attenuate torque dips.
in addition, the machine is equipped with the Assist & Slipper dual-cam assisted clutch to soften the clutch grip and avoid rear-wheel lock-up in the event of a violent downshift. Overall, the engine has been designed to be as compact as possible, so that its weight and overall dimensions are almost identical to those of its predecessor, the Ninja 300cm3.
other solutions have also helped to reduce the bike's weight (lighter frame and swingarm, forged camshafts, compact clutch, less fluid carried, lighter exhaust). The Ninja 400 claims 168 kg. Among the welcome little extras is the patented system that places the fan behind the radiator, allowing hot air to be evacuated away from the rider, thus avoiding big hot flushes in traffic jams. The other advantage is that it uses fewer insulating parts, saving precious grams.

Wheels: 5-spoke star wheels similar to those on the Ninja 650. The rear gum is 150 mm, rather wide for its power level.
For braking, the front is slowed by a 310 mm semi-floating petal disc, bitten by a two-piston caliper. Rear braking is entrusted to a 220mm petal disc and a two-piston caliper. All with conventional ABS.
The riding position is sporty but not radical. The 785mm seat height and slim front end allow smaller riders to put their feet down with ease. The design has also evolved. Inspired by the ZX 10-R, it also includes nods to the H2, Kawa's sportbike benchmark. The Ninja 400's design has aplomb. In profile, the front end is determined, with a more upright nose and a frank look. The connection with the H2 is underlined by the two small spoilers under each headlight. The same applies to the rear seat. All front and rear lighting is full LED.
The instrumentation, too, has all the bells and whistles! This Ninja 400 benefits from the old Ninja 650's dashboard, with its needle-type rev counter framed on the left by a bar of indicator lights and on the right by a large multi-function LCD screen. The gear indicator is still there, and only the shift-light has been removed. No TFT yet, but that will come one day. Although the fuel tank holds just 14 liters, the machine's range is estimated at 350 km.
As you can see, this little bike has everything you need to enjoy the twists and turns of our small country roads, without risking losing your license in the slightest straight line..

Bikers' reviews Leave a review - 7 reviews
Despite its sporty, eye-catching looks, this Ninja 400 remains a reasonable and very safe motorcycle, with no need for traction control or other gadgets. Its safety lies in its linear engine, its ability to enter bends, its powerful yet easily controllable braking and its riding position, which is sportier than a roadster but not radical. On fast lanes, I love leaning slightly behind the little bubble! Its performance is astonishing, and you'll already be able to let go of a lot of lift under acceleration. And let's not forget another important point: reliability! Shortcomings? The duo: don't expect your passenger to feel at ease. And the equipment is a bit sparse. At this price, I haven't found anything better! Rating : 4/5 Respond to Solb13
The only drawback is for the passenger: small seat, uncomfortable, cramped position. I make a lot of trips with my girlfriend, and we have to take a break after 45 minutes. I've had my A license for some time now, and if I decide to leave my Ninja, it's only for my passenger.
The sound of the original pot too, but it's a matter of taste: you can hear that it's only a 400 when you start it up. After that, another pot can be fitted if necessary
If you've just got your motorcycle license and you're not planning to go on long, regular rides with a passenger, don't hesitate, it's top of the range! And its sporty look <3 Rating : 5/5 Respond to Dennis
For 300â'¬ you can find aftermarket Euro4 mufflers ( Arrow,ixil, Ixrace... ) that let you enjoy a livelier sound
For the price, the 2020 remains at 6199â'¬, no increase (unlike the z400, which takes an extra 100â'¬) Rating : 5/5 Respond to Kouign
A 125 with 45hp
2 shortcomings
Slippery seat and duo sacrificed for looks
The rest is formidable
The example that you don't need more hp to enjoy yourself without frustration
We should see it roll!

Sportbikes have become a niche market, and even more so for small-displacement sportbikes, so why not push the concept to the limit? Sales would be no less good, and it might even arouse more interest among fans of the genre.
