How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a show-stopping custom cruiser for boulevard cruising and statement-making rather than outright performance or long-distance touring.
- Built for
- A bold, flamboyant V-twin chopper with aggressive styling, a wide drive frame, and a laid-back stance that prioritizes attitude and visual impact over agility.
- Not ideal for
- This is not the right bike for riders seeking nimble cornering, off-road capability, or a nimble daily commuter.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
