How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- The original dual-sport adventure tourer: built to cover long distances on tarmac and rough tracks alike, ideal for exploration and round-the-world journeys.
- Built for
- A rugged, unhurried icon. The torquey air-cooled boxer and bulletproof shaft drive make it dependable and characterful rather than fast - the bike that founded the GS legend.
- Not ideal for
- Not for speed seekers, track riders, or those wanting nimble technical enduro performance; its weight and modest power frustrate anyone chasing outright pace.
