Rider Profile

Best ForThis bike suits beginner and younger riders, including those on a learner-legal or moped-class license, who want a light, playful machine to build skills on.
PurposeIt's built for supermotard-style fun, flicking through city streets, tight backroads, and light urban stunting rather than any serious distance riding.
Rider FitIts tiny 99 kg dry weight and low-ish 860 mm seat height make it extremely manageable for smaller or less experienced riders to handle and pick up.
CharacterA tiny two-stroke supermotard, it's buzzy, revvy, and eager to be thrashed, rewarding an aggressive, playful riding style over smooth cruising.
Not Ideal ForIt's not for anyone wanting real highway speed, long-distance touring comfort, or a bike capable of carrying a passenger any real distance.
