| Rider Fit | Very light wet weight and tall seat height demand an active, fit rider comfortable standing and shifting body weight through rough terrain. |
| Character | Raw, high-strung, and reward-driven, this bike delivers sharp, punchy 2-stroke power and razor-sharp agility for riders who like to work the bike hard. |
| Not Ideal For | Not for riders seeking comfort, highway capability, passenger accommodation, or a low-maintenance, easy-going ride. |
