Best for: It exists purely to carve up tight tarmac circuits and technical mixed-surface courses with razor-sharp direction changes, not to cover distance or haul gear.
Built for: Expect an explosive, visceral character with instant throttle response, flickable handling, and a chassis that thrives on aggressive lean angles and hard braking into corners.
Not ideal for: This bike is not for beginners, commuters, passengers, or anyone seeking comfort, wind protection, or long-distance touring capability.

Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
