2020 Kawasaki Ninja ZX-6R — Should You Buy One?

Typical asking price: $8,500–$11,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

A proper 600-class supersport — the ZX-6R (actually 636cc) screams to a high redline, handles razor-sharp, and is one of the last of a dying breed. It's a track-day favorite, which is exactly the concern: many were crashed, tracked, or thrashed. A pampered street bike is a thrilling, reliable weapon; a beaten track refugee is a project. Scrutinize for crash damage and verify it wasn't a race bike.

What we checked

No public record to reconcile against

We don't yet have a public record to check this one against. Federal complaint records thin out badly on older vehicles, so there is little to check against. What follows is our own write-up, and it has not been reconciled against an official record. Treat it as a starting point, not a verdict.
