Rider Profile
| Best For | This is a purpose-built competition trial machine best suited to skilled or dedicated novice trial riders rather than general street riders. |
| Purpose | Designed purely for technical trial competition and obstacle riding at very low speeds, not for straight-line speed or road use. |
| Rider Fit | Its ultra-light dry weight and low seat height make it easy to muscle around and paddle-balance, though the tall ground clearance and no-seat riding style demand strong legs and core stability. |
| Character | A featherweight, razor-agile two-stroke trials tool that rewards precise throttle and clutch control with incredible low-speed balance and obstacle-clearing ability. |
| Not Ideal For | Not suitable for riders wanting a comfortable seat, highway capability, passenger carrying, or any form of touring or daily commuting. |
