Rider Profile
| Best For | This is a full-on competition motocrosser best suited to intermediate through expert off-road riders who already know how to manage a peaky two-stroke power delivery. |
| Purpose | Built purely for motocross track riding and racing, not for street use, commuting, or general adventure riding. |
| Rider Fit | Tall 975mm seat height, light 103kg wet weight, and aggressive ergonomics demand good rider fitness, strong legs, and comfort standing on the pegs for extended periods. |
| Character | A raw, high-revving two-stroke that rewards aggressive clutch and throttle control with explosive acceleration and razor-sharp cornering agility. |
| Not Ideal For | Not suitable for beginners, passengers, commuting, touring, or anyone seeking a comfortable, low-maintenance, road-legal motorcycle. |
