How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for effortless, brutal straight-line acceleration and long-haul cruising with a muscular, intimidating presence rather than for flicking through tight corners.
- Built for
- A charismatic power cruiser that combines a torque-monster three-cylinder engine with premium suspension and brakes for a surprisingly composed ride given its size.
- Not ideal for
- Not a good fit for new riders, off-road use, or anyone wanting a light, nimble bike for tight urban streets.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
