Rider Profile
| Best For | This is a pure competition trial machine best suited to riders with prior off-road or trial experience, though its light weight makes it approachable for committed beginners willing to learn technical balance skills. |
| Purpose | Built exclusively for technical trial competition and obstacle-based off-road riding rather than any form of road use, speed, or distance travel. |
| Rider Fit | Its extremely low dry weight of 66 kg and tall 640 mm seat height demand active standing riding, strong core balance, and leg strength rather than raw physical bulk. |
| Character | A precise, feather-light, high-revving two-stroke tool designed for delicate throttle control, hopping over obstacles, and momentum-based technical maneuvers. |
| Not Ideal For | This is not suitable for riders wanting highway travel, passenger carrying, everyday commuting, or any kind of touring comfort. |
