Rider Profile

Best ForIdeal for beginners and A1/learner licence holders; light, forgiving power and an automatic clutch make it easy for new riders.
PurposeA supermoto-styled 125 built for city commuting and fun urban back-road blasts, not distance or speed.
Rider FitTall, upright motard stance with wide bars, 17-inch road wheels and a slim, narrow chassis that flicks easily through traffic.
CharacterA cheeky, nimble learner motard with scrambler looks-playful and eager in town but modest on outright pace.
Not Ideal ForNot for highway touring, two-up loaded trips, genuine off-road use, or experienced riders wanting real speed.
