How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It exists primarily as a straight-line spectacle and show-stopping cruiser, built for thunderous acceleration and attention rather than nimble riding.
- Built for
- It has an outrageous, brash personality defined by raw V8 torque, automotive-derived engineering, and unapologetic size and presence.
- Not ideal for
- It is not for riders seeking agile cornering, off-road capability, or a lightweight, easy-to-manage everyday bike.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
