Rider Profile
| Best For | Best suited to intermediate and experienced off-road riders comfortable with a tall, light, powerful competition enduro bike. |
| Purpose | Built for serious enduro riding, trail competition, and technical off-road terrain rather than road use. |
| Rider Fit | The tall 940mm seat height and firm off-road stance demand good rider fitness, leg length, and confidence standing on the pegs. |
| Character | A featherweight, high-revving thumper with race-bred suspension and chassis that rewards an aggressive, physically engaged riding style. |
| Not Ideal For | Not a good fit for new riders, commuters, passengers, or anyone wanting a comfortable long-distance road machine. |
