How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for effortless, high-torque long-distance cruising rather than nimble sport riding, with massive shaft-driven muscle to eat highway miles.
- Built for
- A brutish, torque-monster tourer that flexes a huge triple-cylinder engine while wrapping the rider in cruiser-style comfort and long-haul amenities.
- Not ideal for
- This is not the bike for riders seeking flickable agility, off-road capability, or a lightweight, easy-to-manage commuter.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
