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
Checked against public records, 2026-09-25
NHTSA holds 2 owner complaints for the 2020 KTM 390 Duke, and no recall campaigns.
That is too small a record to read a pattern from, so we are not going to pretend otherwise — with numbers this low one owner moves the percentage by a lot. What has been filed is grouped under the engine (1), electrics and electronics (1). Treat those as things to look at, not as the vehicle's known weaknesses. A thin file usually means few of these were sold or few owners filed. It is not evidence the vehicle is trouble-free, and the issues below are our own research rather than a reading of this record.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
