Rider Profile

Best For	This bike suits beginner to novice riders who want a light, non-intimidating machine to build skills and confidence on.
Purpose	It's designed as a small-capacity supermotard for zipping through city streets, tight corners, and short playful rides rather than sustained high-speed travel.
Rider Fit	The tall-ish 880mm seat height combined with a very light 121kg dry weight makes it easy to manage for most body sizes despite the perch.
Character	It has a nimble, flickable, go-kart-like character with sharp steering geometry and minimal weight, rewarding playful riding over straight-line speed.
Not Ideal For	It's not suited for riders seeking highway touring, high-speed cruising, serious off-road adventure, or carrying a passenger in comfort.
