Rider Profile
| Best For | Ideal for beginners and A1 licence holders learning sportbike dynamics; also a fun, cheap toy for experienced riders. |
| Purpose | A pint-sized sport machine for spirited canyon carving, commuting and track-day schooling, teaching real sportbike technique on low power. |
| Rider Fit | Committed sporty stance with clip-ons and rearsets, tall 824mm seat, but featherweight 147kg makes it easy to flick and manage. |
| Character | Energetic, revvy and razor-sharp; a proper baby superbike that rewards momentum and precise lines rather than brute power. |
| Not Ideal For | Not for riders wanting highway speed, two-up touring, long-distance comfort or any off-road use. |
