Rider Profile
| Best For | This is a purpose-built trial competition machine best suited to riders with dedicated trials skill or serious off-road experience, not casual or novice riders. |
| Purpose | Designed exclusively for technical trial competition, requiring balance, throttle control, and obstacle negotiation rather than sustained speed. |
| Rider Fit | Its featherweight dry mass and tiny 2.5 litre tank demand an active standing riding style with constant body movement and no allowance for long seated stints. |
| Character | A razor-sharp, ultra-light two-stroke trials tool that rewards precision and finesse over raw power, with class-leading agility for climbing, hopping, and balancing over obstacles. |
| Not Ideal For | This is not suitable for anyone wanting a comfortable commuter, a highway tourer, a passenger-carrying bike, or a machine with meaningful top-end speed. |
