Rider Profile
| Best For | Best suited to riders with prior off-road or trial experience, since balance and clutch control matter far more than throttle confidence. |
| Purpose | This is a dedicated competition trial machine built for tackling technical obstacles at walking pace, not for covering distance or riding on paved roads. |
| Rider Fit | Its extremely light weight of 85 kg makes it easy to muscle around and hop over obstacles, favoring balance and technique over strength. |
| Character | A featherweight, high-revving two-stroke trial bike that rewards precise, deliberate inputs and thrives in slow, technical terrain. |
| Not Ideal For | Not for riders wanting a comfortable, fast, or practical bike for road use, touring, or carrying a passenger. |
