- Built as a lightweight, high-revving sport bike for spirited backroad riding and track-day thrills rather than practical transportation.
- Built for
- A raw, buzzy, and thrilling two-stroke that rewards riders who love revving it out near 10,000rpm and carving corners on its light aluminium chassis.
- Not ideal for
- This is not the bike for riders wanting comfort, passenger space, long-distance touring capability, or a forgiving, low-maintenance ride.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
