Rider Profile

Best ForBest suited to intermediate riders who want a light, flickable machine to sharpen their cornering skills, though beginners can also manage its low weight and mild power.
PurposeBuilt for supermoto-style fun: tight, twisty roads, tarmac corner-carving, and playful urban riding rather than long distance or heavy off-road work.
Rider FitIts tall seat height and slim, lightweight chassis make it easy to muscle around but the lofty stance may challenge shorter riders at a stop.
CharacterA nimble, high-strung little supermoto that rewards aggressive lean angles and quick direction changes over outright speed.
Not Ideal ForNot the right choice for riders wanting high-speed touring, passenger comfort, or serious off-road adventure capability.
