Rider Profile
| Best For | This is a specialist machine best suited to riders with some trials or technical off-road experience, though beginners keen on learning trials skills can also start here under guidance. |
| Purpose | Built purely for competitive and recreational trials riding, focused on tackling obstacles, steep and technical terrain at very low speeds rather than covering distance. |
| Rider Fit | Its extremely light dry weight and low seat height make it very manageable physically, but trials riding demands strong core balance, leg strength, and stamina for standing and maneuvering. |
| Character | A featherweight, razor-sharp handling bike with a torquey low-end engine tuned for control and balance rather than outright speed. |
| Not Ideal For | This is not the bike for riders wanting a comfortable seat, highway speed, luggage capacity, or a passenger-friendly ride. |
