Rider Profile

Best ForSuited to newer or younger riders who want a light, forgiving small-bore supermoto to build skills on before moving to bigger machines.
PurposeBuilt as a nimble, urban-friendly supermoto for weaving through traffic, flicking around back roads, and having fun rather than covering long distances quickly.
Rider FitThe low dry weight and 900mm seat height keep it manageable for shorter or lighter riders, though the tall-ish stance still requires reasonable inseam and confidence at a stop.
CharacterA cheeky, playful little street bike with sharp steering geometry and supermoto styling that rewards revving it hard and throwing it into corners.
Not Ideal ForNot for riders wanting sustained highway speed, long-distance touring comfort, or serious off-road capability given its road-biased 17 inch wheels and modest 125cc output.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
