購入者が知っておくべきこと
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.

"はるかに尊敬に値する、忘れ去られた日本の宝石。"
私が87年のZX-4Rで8,000マイル近く走ったんだけど、その直列4輪は本当に病みつきになる。9,000rpmを超えると激しく引っ張って、12,000回転に向かって叫ぶような排気量の2倍の音だ。ハンドリングは80年代半ばのバイクにしてはきわめてシャープで、168kgは読むよりも軽く感じられ、狭い山道を自信を持って走ることができます。とはいえ、7,000 rpm未満ではガットレスで動きが鈍くなるため、パワーバンドに留まるために絶えずブリッピングやシフトダウンを行っていない限り、街への通勤は真の雑用になります。2024年には、部品の入手可能性が一番の決め手です。OEMガスケットやキャブジェットを見つけると、eBay Japanに何週間も悩まされることになります。

中古購入者レビュー
"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.
