Best for: Built for relaxed boulevard cruising, weekend rides, and showing off classic custom styling rather than for speed or sport riding.
Built for: A laid-back, torque-driven cruiser with the classic thump of an air-cooled Evolution V-twin, prioritizing style, sound, and cruising comfort over agility or acceleration.
Not ideal for: Not for riders seeking sharp cornering ability, high-speed touring comfort, or any kind of off-road capability.

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