Rider Profile

Best ForThis lightweight, low-powered supermotard is best suited to beginner and novice riders building confidence, or licensed learners looking for a nimble first bike.
PurposeIt's designed for playful, flickable fun on tight urban streets and twisty backroads rather than outright speed or distance riding.
Rider FitThe tall 905mm seat height and slim, minimal 101kg dry weight suit riders comfortable balancing a tall stance, though shorter riders may need to tip-toe at stops.
CharacterIt has the character of a scrappy, agile mini-motard that rewards aggressive body language and quick direction changes over raw acceleration.
Not Ideal ForThis is not the right bike for highway touring, carrying a passenger, or riders who prioritize outright power and long-distance comfort.
