Best for: Built for relaxed boulevard cruising and image-driven riding rather than outright performance or long-distance touring.
Built for: A classic fat-tired Harley cruiser that delivers strong low-end torque, a deep V-twin rumble, and unmistakable custom styling over outright speed or agility.
Not ideal for: Not a good fit for riders seeking sharp cornering ability, off-road capability, or a nimble, lightweight machine for tight urban lane-splitting.

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