Rider Profile
| Best For | This is a serious enduro weapon best suited to intermediate through expert off-road riders who already understand two-stroke power delivery. |
| Purpose | Built purely for competitive enduro and technical off-road riding, not as a general-purpose or road-oriented machine. |
| Rider Fit | Its extremely light dry weight and tall 950mm seat height reward an active, standing riding style but demand decent fitness and leg length to manage the suspension travel and technical terrain. |
| Character | A raw, punchy two-stroke with a light chassis and long-travel suspension that thrives on being flicked through tight, technical trails and aggressive terrain changes. |
| Not Ideal For | This is not the right bike for riders wanting comfortable street commuting, passenger carrying, or long-distance paved touring. |
