Best for: Built as an entry-level cruiser for relaxed street riding and around-town cruising rather than performance or long-distance touring.
Built for: A laid-back, classic-styled single-cylinder cruiser that emphasizes simplicity, easy handling, and low-speed charm over outright performance.
Not ideal for: Not a good fit for riders wanting high speed, aggressive cornering ability, serious off-road capability, or comfortable two-up long-distance touring.

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