How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for effortless, brutal roll-on acceleration and long-haul cruising rather than for track days or tight technical roads.
- Built for
- A muscular, torque-monster cruiser with a huge in-line triple engine that delivers massive low-end thrust wrapped in premium cycle parts and modern electronics.
- Not ideal for
- Not the right choice for riders wanting a lightweight, flickable bike for tight twisties or any kind of off-road use.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
