How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- This is a nimble, flickable supermotard built for tight urban streets, sharp cornering fun, and light off-road excursions rather than outright speed or distance covered.
- Built for
- A playful, mischievous city scalpel that thrives on quick direction changes, wheelies, and darting through traffic rather than settling into long, relaxed cruising.
- Not ideal for
- Not a good fit for riders seeking sustained highway speeds, long-distance comfort, or a passenger-friendly, plush-riding motorcycle.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
