2020 KTM 390 Duke — Should You Buy One?

Typical asking price: $3,800–$5,800. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

A sharp, aggressive small naked that punches well above its 373cc — the enthusiast's beginner bike. It's more highly strung than a Japanese equivalent, so the maintenance and any crash history matter more. Fun, and not quite as durable as its rivals.

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.
