Rider Profile
| Best For | This is a competition trial machine built for skilled riders who already understand clutch and balance control at near-zero speed, not for beginners seeking a general-purpose bike. |
| Purpose | It exists purely for technical trials competition and obstacle work, using extreme lightness and suspension travel to conquer rocks, logs, and steep terrain rather than to cover distance. |
| Rider Fit | Riding it demands strong core balance, leg strength, and standing endurance since there is no real seat and the tiny fuel tank confirms sessions are short and intense. |
| Character | It feels featherlight, explosive off idle for hopping obstacles, and razor-sharp in direction changes thanks to its sub-70kg dry weight and short wheelbase. |
| Not Ideal For | It is not suited for anyone wanting highway travel, passenger carrying, everyday commuting, or comfort over long distances. |
