How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Designed as a versatile everyday roadster that excels at commuting, weekend blasts, and learning to ride briskly rather than as a dedicated track or long-distance tool.
- Built for
- The 660cc triple delivers a smooth, torquey, and vocal power delivery that feels lively without being intimidating.
- Not ideal for
- Not the ideal choice for riders wanting serious off-road capability, high-speed track dominance, or dedicated two-up long-haul touring comfort.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
