A Kawasaki Ninja ZX-4R foi revivida em 2023 após uma longa ausência, originalmente com raízes na era das motos esportivas de pequena cilindrada do final dos anos 1980. O modelo 2023 foi apresentado como uma moderna moto esportiva de quatro cilindros em linha de 400 cc, preenchendo um nicho entre a ZX-25R e máquinas maiores da classe litro, visando pilotos que buscam uma máquina de alta rotação e desempenho acessível. Ele rapidamente ganhou atenção por oferecer uma experiência genuína de supersport de quatro cilindros a um preço médio, tornando-o notável em mercados em todo o mundo, incluindo os EUA, onde o original nunca foi vendido oficialmente.

O que os compradores devem saber
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.

"A joia esquecida do Japão que merece muito mais respeito."
Eu coloquei quase 8.000 milhas em uma ZX-4R de 87 e essa quarta em linha é genuinamente viciante — ela ultrapassa 9.000 rpm e grita em direção a 12.000, como algo com o dobro da cilindrada. O manuseio é nítido para uma bicicleta de meados dos anos 80; 168 kg parecem mais leves do que parecem e você pode percorrer estradas estreitas nas montanhas com confiança real. Dito isso, abaixo de 7.000 rpm, é covarde e lento, o que torna o deslocamento urbano uma tarefa genuína, a menos que você esteja constantemente diminuindo a marcha para se manter na banda de potência. A disponibilidade de peças é o verdadeiro assassino em 2024 — encontrar juntas OEM ou jatos de carboidratos significa assombrar o eBay Japan por semanas.

Avaliação do comprador usado
"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.
