How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's built as a lightweight, minimalist retro roadster for relaxed street riding rather than speed or distance covering.
- Built for
- It has old-school single-cylinder charm with a thumping, low-revving engine and stripped-down custom styling that rewards a slower, deliberate riding style.
- Not ideal for
- This is not the bike for riders wanting quick acceleration, long highway touring comfort, or any serious off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
