Rider Profile

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