Rider Profile

Best For	This is a tall, kick-started big-bore single best suited to riders with prior off-road or dual-sport experience, not absolute beginners.
Purpose	Built primarily as a serious enduro machine for trails, gravel, and technical terrain, with occasional road use as a secondary role.
Rider Fit	The 910mm seat height and 148kg dry weight demand decent rider height and fitness, especially for picking the bike up off-road or paddling at a stop.
Character	A raw, torquey single-cylinder enduro with a lively, physical riding experience and minimal creature comforts.
Not Ideal For	Not a good fit for riders wanting a smooth, comfortable highway tourer or a low, easy-to-handle commuter bike.
