Kawasaki Z400 Review

Used Buyer Review

The Z400 is one of those rare bikes that actually delivers on its hype. Kawasaki nailed the balance between accessible and genuinely fun — that parallel twin pulls cleanly from low revs and rewards you when you wind it out toward the 10,000rpm redline. It doesn't feel like a compromise machine, which is rare at this displacement. Used examples are everywhere right now, mostly from newer riders who upgraded, which means plenty of choice but also plenty of abuse to watch for. Check the fairings carefully — the naked styling means any tip-over scratches are obvious and expensive. Front fork seals are a known weak point on earlier examples, so get underneath and look for oil weeping around the stanchions. Chain and sprocket wear tells you a lot about how the previous owner treated it. These bikes respond badly to neglect but reward sensible maintenance with serious reliability.
