KTM engine problems

Owners have filed 82 complaints with NHTSA about the engine on KTM vehicles — 20% of everything reported about the brand, across 31 models. The model that accounts for most of them is the KTM 790 Adventure R, worst in 2021.

These are raw counts. A model that sold in millions appears near the top for that reason alone — the grade never compares one model with another.
