KTM 1390 Super Adventure S EVO 2025

With the 1390 Adventure S EVO, KTM shows what is technically possible, packing new and improved comfort features such as a wonderfully functioning automatic transmission, adaptive cruise control or semi-active suspension into a bike that is extremely mature after ten model years and is certainly one of the sportiest touring enduros. Whether relaxed when touring, even as a couple, or with a knife in your teeth on the way to the king of the mountain passes - the SAS is proof on the move that comfort and sport are not mutually exclusive.
