How it rides
Editorial estimate from the spec sheet - not lab tested- 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.
