Best for: Built for laid-back boulevard cruising and style-focused riding rather than outright performance or long-distance touring.
Built for: A muscular, blacked-out custom cruiser with fat tires and a punchy V-twin that rewards relaxed, torque-driven riding over aggressive cornering.
Not ideal for: Not a good fit for riders seeking sharp handling, off-road capability, or a nimble machine for tight, technical roads.

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