How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- A versatile sport-touring V-twin built for mixing weekend backroad rides with reasonably comfortable longer journeys.
- Built for
- Delivers a torquey, characterful V-twin growl with sporty handling cues like an upside-down fork and twin front discs, without being a full-on racer.
- Not ideal for
- Not the right choice for off-road adventures, novice riders wanting a light learner bike, or those chasing outright superbike performance.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
