The Kawasaki Ninja Zx-4r has a top speed of 200 km/h (estimated; approximately 185-200 km/h real-world), produces 77 hp and weighs 187 kg. Motoryk rates it 8.5/10.
La Kawasaki Ninja ZX-4R a été relancée en 2023 après une longue absence, remontant à l'origine à l'ère des motos de sport à petite cylindrée de la fin des années 1980. Le modèle 2023 a été présenté en tant que moto de sport moderne à quatre cylindres en ligne de 400 cm3, occupant une place entre la ZX-25R et les machines plus grandes de la classe litre, ciblant les pilotes à la recherche d'une machine performante accessible et à haut régime. Il a rapidement attiré l'attention en offrant une véritable expérience de supersport à quatre cylindres à un prix moyen, ce qui le rend remarquable sur les marchés du monde entier, y compris aux États-Unis, où l'original n'a jamais été officiellement vendu.

Ce que les acheteurs doivent savoir
Rare 4-Cylinder 400cc
The ZX-4R is one of the only modern 400cc inline-four sport bikes available, making it unique in its class. This engine configuration delivers a high-revving, engaging ride that most competitors simply can't match.
Strong Resale Value
Due to its niche appeal and limited production numbers, the ZX-4R holds its value exceptionally well compared to similar displacement bikes. High demand and low supply mean used examples rarely sell at a significant discount.
Watch Valve Clearances
Like most high-revving inline-four engines, the ZX-4R requires diligent valve clearance checks per Kawasaki's service intervals to avoid performance issues. Skipping this maintenance is the most common mistake owners make and can lead to costly repairs.

"Le joyau oublié du Japon qui mérite bien plus de respect."
J'ai parcouru près de 8 000 miles sur une ZX-4R de 1987 et ce quatre cylindres en ligne crée une véritable dépendance : il tourne fort au-delà de 9 000 tr/min et crie vers les 12 000 tr/min, soit deux fois plus de cylindrée. La maniabilité est exceptionnelle pour un vélo du milieu des années 80 ; 168 kg, c'est plus léger qu'il n'en paraît, et vous pouvez vous débrouiller sur des routes de montagne étroites en toute confiance. Cela dit, en dessous de 7 000 tr/min, c'est lent et intrépide, ce qui fait des déplacements en ville une véritable corvée, à moins de devoir constamment passer à la vitesse supérieure pour rester dans la plage de puissance. La disponibilité des pièces est la véritable cause de décès en 2024. Trouver des joints d'origine ou des gicleurs de carburateur revient à hanter eBay Japan pendant des semaines.

Évaluation d'un acheteur d'occasion
"The best small-bore inline-four you can buy right now."
$7,500-$10,500 usedThe ZX-4R is genuinely one of the most exciting small-displacement bikes Kawasaki has built in years, and the used market is starting to make sense financially. That inline-four screamer revving to 17,000rpm delivers a hit that'll embarrass plenty of middleweight twins when you're in the upper half of the rev range. First-year examples (2023) occasionally show up with throttle-by-wire glitches and some owners reported rough idle behavior cold — worth checking on any used example you inspect. Practically speaking, these things have been thrashed. Most ZX-4R owners bought them specifically to push limits, so inspect brake pads, chain wear, and look underneath for fairing rash religiously. The quickshifter on base models is an optional extra, so confirm what spec you're actually buying. Service intervals are tighter than a 600, and valve clearance checks aren't cheap. That said, if the mechanicals are solid, you're getting a chassis that genuinely communicates, suspension that's adjustable and capable, and a soundtrack that makes riding genuinely addictive again. Worth every cent of a clean example.
