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
