How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Best suited to commuting, learning, and short fun rides around town rather than any serious performance riding.
- Built for
- It has genuine GSX-R styling and a keen, revvy little single-cylinder engine that rewards being thrashed through the gears despite its modest output.
- Not ideal for
- This is not the bike for highway touring, carrying a passenger any real distance, or riders seeking outright speed and power.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
