2019 Kawasaki Ninja 400 — Should You Buy One?

Typical asking price: $4,000–$6,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

The best beginner sportbike of its generation — light, quick enough to be fun, and forgiving enough to learn on. The 399cc twin is durable. Because it's a learner bike, crash and drop damage is the primary risk, not mechanical failure.

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.
