2021 KTM 890 Duke — 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
The 'Super Scalpel' — KTM's 890 Duke is a razor-sharp middleweight naked with a punchy parallel-twin and hooligan attitude, lighter and more focused than the bigger super-nakeds. It's a blast, but KTMs get ridden hard and need attention to maintenance. A clean, well-serviced 890 Duke with records is one of the most fun middleweight nakeds going; verify service and inspect for abuse.
What we checked
Checked against public records, 2026-09-25
NHTSA holds 1 owner complaint for the 2021 KTM 890 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 electrics and electronics (1), the lights (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.
