Rider Profile

Best ForSuits riders from intermediate level upward who want a smooth, easygoing machine without needing advanced skill to manage it.
PurposeBuilt as a versatile all-rounder for commuting and relaxed sport-touring rather than outright performance or racing.
Rider FitA moderate 228 kg curb weight and 760 mm seat height make it manageable for most adult riders, though the heft is noticeable at low speed and standstill.
CharacterThe inline-three engine and shaft drive give a smooth, refined, understated character typical of BMW's K-series tourers of the era.
Not Ideal ForNot a good fit for riders seeking sharp cornering agility, off-road capability, or high-speed sportbike performance.
