How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's best suited to light urban commuting, learning to ride, and short low-speed jaunts rather than any serious performance riding.
- Built for
- The single-cylinder retro-naked styling and modest, torque-light power delivery give it a docile, approachable, old-school charm.
- Not ideal for
- It is not suited to highway touring, carrying a passenger any real distance, or riders seeking speed and excitement.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
