2020 KTM 1290 Super Adventure S — Should You Buy One?
Typical asking price: $12,000–$17,000. There are 2 high-severity known issues you need to know before handing over a check.
Kestrel Take
A ferociously fast, tech-laden big adventure bike with the 1301cc V-twin. Genuinely thrilling and genuinely demanding to own — expensive valve services, complex electronics, and real maintenance needs. Buy one with a complete service file and a nearby KTM dealer, or not at all.
What we checked
Checked against public records, 2026-09-25
NHTSA holds 2 owner complaints for the 2020 KTM 1290 Super Adventure S, 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 fuel system (2), electrics and electronics (1), the brakes (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.
