KTM 390 Enduro R 2026

The KTM 390 Enduro Bike R is exactly what many have been missing for a lengthy period of time: a true dual-sport machine that does not take refuge in extremes. It is neither an uncompromising hard enduro nor a stud-trimmed naked bike, but a versatile tool for everyday use, travelling and off-road. Easy to handle, agile enough for country roads, comfortable enough for longer distances and equipped with a suspension that also makes ambitious off-road riding possible. It does have minor weaknesses such as its noticeable weight, slight vibrations or a snappy rear brake - but these are relativised by the attractive price. Anyone who values versatility more than technical perfection in a single area will find the 390 Enduro R a well thought-out, modern and very balanced A2 bike.
