Rider Profile
| Best For | Suited to beginner through experienced off-road riders; forgiving power delivery but the tall seat demands some confidence and leg length. |
| Purpose | A dedicated enduro/trail machine built to tackle dirt, single-track and rough terrain, with only occasional light paved-road duty. |
| Rider Fit | Tall 945mm seat, slim, upright and roomy with huge 325mm ground clearance; light at 119kg dry, easy to flick around but reaches for the ground. |
| Character | Rugged, torquey liquid-cooled thumper - playful and tireless off-road, mechanically simple and dependable, happiest away from tarmac. |
| Not Ideal For | Not for tourers, highway commuters, passenger hauling or track riders; the tiny tank, thin seat and off-road tires punish long paved miles. |
