presentation of the Z 400 2020
The A2 license is like diapers, getting dumped or getting your first job as a m.... you've got to take it, and there's no choice. But there's no reason to be sad about it, either, with wheeled tractors. The market has understood this, either with high-value, high-capacity wheels... strangled by the clamping system. Or with small-displacement bikes that are starting to look good. Have you seen the 390 Duke? The 500 Leoncino? The 401 Vitpilen?
Kawa was absent from this segment for a while... only to come back stronger, more convincing, more sugomi with the new Z 400.
Let's think of this Kawa as the worthy descendant of the Z 300, though.... More like the naked version of the Ninja 400. Take away the cladding and you'll find all the ins and outs of the little sports bike. The technical choice is simple, easy and no-nonsense. It's all there for you to enjoy, right up to the limits imposed by your "young" licence.
Powered by a 399 cm3 twin-cylinder, the Z produces 45 hp at 10,000 rpm. That's 6 hp more than the 300. Torque is the big winner, with more than 1 mkg gained.
No surprises or disappointments to be expected on the performance front: the roadster weighs just one kilogram less than the sports car. Only the top speed will have to be revised downwards, as the absence of protection acts as an aerodynamic brake.

Kawasaki has worked hard enough to make us forget where it came from. By its silhouette, of course, and by the welcome on board. A handlebar replaces the two straps and should offer a more relaxed riding position, although the Ninja's is already very comfortable. The speedometer is almost identical to that of the 650 / 900. Reasonable seat height at 785 mm, 167 kilos ready to ride, overall finesse, ultra-smooth clutch, the medium Z presents a good welcome. Medium-sized? Yes, we can no longer say small since the 125 joined the catalog. Hmmm, we'd have liked a 12V socket or at least a USB port. Most buyers will always have a phone to charge or an mp3 to plug in.

Kawasaki has completed the Z family from one end to the other. Well, almost. We wouldn't be against a Z 1300 descendant. For the time being, one of the priorities is to make the 300 / 400 category more attractive. The compulsory A2 will help in this task, while the Z 400 roadster is working hard to carve out a place for itself. Derived from the Ninja, more powerful and accomplished than the ex-Z-300, it is also one of the most generously powered, even sniffing out the CB 500. Nothing is certain in this category, but the machine will benefit from the Z spirit and image. A considerable asset in the balance.
