How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's built primarily for spirited cornering and sporty road riding rather than outright top-end speed, thanks to the detuned 46.9 HP twin in a lightweight chassis.
- Built for
- Agile, light, and eager to change direction, this bike rewards smooth inputs and flowing cornering lines more than brute acceleration.
- Not ideal for
- It's not the right choice for riders wanting high-speed highway overtakes, long-distance touring comfort, or any kind of off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
