Rider Profile

Best ForThis tiny 50cc supermotard suits beginners and playful experienced riders alike, since its low power ceiling makes mistakes far less costly than on a full-size bike.
PurposeBuilt for sharp, flickable fun on tight city streets, mini-moto track days, and supermotard-style cornering practice rather than outright speed or distance.
Rider FitIts featherweight 81.5 kg dry mass and compact dimensions make it exceptionally easy to muscle around, flick side to side, and pick up if dropped, suiting smaller or less physically strong riders well.
CharacterA cheeky, high-revving two-stroke minimoto that rewards aggressive throttle and body-english riding over raw horsepower, delivering grins rather than grunt.
Not Ideal ForNot suitable for highway travel, long-distance touring, carrying a passenger, or riders wanting strong acceleration and top-end speed.
