Best for: Built for boulevard cruising and making a bold visual statement rather than for outright speed or long-distance touring.
Built for: A big, muscular, stripped-down custom cruiser with fat tires and a thumping V-twin that rewards style-conscious riders who enjoy being seen as much as riding.
Not ideal for: Not a good fit for riders wanting agile cornering, off-road capability, or a sporty high-rpm ride.

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