Rider Profile

Best ForThis is a minibike built for playful track riders and pit-bike enthusiasts, not a machine for beginners seeking a first real motorcycle or for licensed riders wanting road transport.
PurposeDesigned purely for minimoto circuit fun and sharpening cornering technique at low cost and low risk.
Rider FitIts tiny 425mm seat height and 22kg dry weight demand a small, lightweight rider who can fold onto a compact frame comfortably.
CharacterA featherweight, high-revving pocket racer that rewards aggressive lean angles and quick flicks rather than outright speed.
Not Ideal ForThis is not suitable for anyone wanting highway travel, touring, passenger carrying, or off-road adventuring.
