How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built primarily as a nimble city and canyon-carving streetfighter rather than a long-distance or off-road machine.
- Built for
- A punchy, single-cylinder naked bike with sharp handling, strong brakes, and an eager, playful attitude that rewards aggressive riding.
- Not ideal for
- Not the right choice for riders seeking a plush, wind-protected long-haul tourer or a capable off-road adventure companion.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
