Rider Profile
| Best For | This is a specialist competition trials machine best suited to skilled or dedicated trials riders, not beginners looking for a general-purpose bike. |
| Purpose | Built purely for low-speed technical trials competition, focused on balance, obstacle negotiation, and precision control rather than speed or distance riding. |
| Rider Fit | Its featherweight dry weight and tiny seat height make it extremely easy to muscle around and paddle with the feet, though the lack of a seat and tall suspension travel demand active standing riding and good core balance. |
| Character | A featherlight, purpose-built two-stroke trials weapon with sharp, direct handling, minimal weight, and razor-focused off-road agility. |
| Not Ideal For | This is not the bike for anyone wanting a comfortable seat, highway speed, luggage capacity, or a passenger-friendly ride. |
