Best for: Built for relaxed, torque-rich boulevard cruising and light touring rather than outright speed or sport riding.
Built for: A big-hearted boxer cruiser that rewards laid-back throttle-rolling riding with deep torque and classic shaft-drive character over outright agility.
Not ideal for: Not the right choice for riders seeking sharp cornering ability, off-road capability, or a light, flickable machine for tight city lanes.

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