Rider Profile

| Purpose | Built purely for closed-course motocross racing and serious off-road competition, not for commuting or general road use. |
| Rider Fit | At just 100 kg dry with a tall 950mm seat height and no passenger accommodation, it demands good rider fitness, height, and off-road bike control confidence. |
| Character | A light, high-revving, race-bred single-cylinder four-stroke with premium WP suspension and a steel double-cradle frame, delivering sharp, aggressive, track-focused handling. |
| Not Ideal For | Not suitable for riders wanting comfort, highway touring capability, passenger carrying, or an easy first bike. |
