How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for leisurely, style-focused riding around town and on quiet backroads rather than any kind of performance or distance work.
- Built for
- A charming, retro-styled single-cylinder cruiser that prioritizes classic looks, simplicity, and a relaxed low-speed ride over outright capability.
- Not ideal for
- This is not the bike for riders wanting highway touring comfort, off-road capability, or any real straight-line performance.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
