Best for: Built for relaxed, torque-driven boulevard cruising and stylish around-town riding rather than outright speed or long-distance touring.
Built for: A classic air-cooled V-twin custom with a stripped-down, blacked-out bobber look, deep torque delivery, and a laid-back, rumbling character over outright performance.
Not ideal for: Not a good fit for riders wanting sharp cornering ability, off-road capability, or a bike optimized for long highway touring comfort.

Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
