Rider Profile

Best ForBest suited to new or young riders, often on a learner license, who are cutting their teeth on a small-displacement supermoto-styled machine.
PurposeDesigned for short, fun, nimble trips around town and playful backroad scratching rather than any serious speed or distance work.
Rider FitA very light and compact bike that suits smaller and lighter riders and requires minimal physical strength to handle.
CharacterA cheeky, flickable mini-supermoto that rewards enthusiastic riding at low speeds with sharp steering and a lively feel.
Not Ideal ForNot for riders wanting real highway speed, long-distance comfort, or genuine off-road capability.
