How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a comfortable, practical all-rounder for commuting, backroad riding, and light touring rather than outright performance.
- Built for
- A classic BMW boxer-twin character: relaxed, torque-driven, mechanically distinctive, and reassuringly stable rather than exciting.
- Not ideal for
- Not for riders chasing high-speed thrills, track-day lap times, or any serious off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
