Rider Profile

Best ForThis lightweight supermoto suits beginner to intermediate riders who want a nimble, confidence-inspiring machine to build skills on.
PurposeBuilt primarily for flickable urban riding and playful backroad cornering rather than outright speed or distance.
Rider FitThe low dry weight and accessible seat height make it manageable for smaller or less experienced riders, though the 900mm seat is still moderately tall.
CharacterA fun, agile little supermoto with sharp handling from its 17-inch wheels and mono-shock setup, but limited by its modest 125cc single-cylinder output.
Not Ideal ForThis bike is not for riders seeking high-speed touring, serious off-road capability, or two-up comfort over long distances.
