Rider Profile

Best ForThis machine is built for skilled trials riders or dedicated beginners specifically learning the discipline, not general-purpose motorcyclists.
PurposeIt exists purely for competitive and recreational trials riding, tackling extreme technical obstacles at near-walking pace rather than covering distance or speed.
Rider FitIts featherlight 67kg dry weight and low seat height make it easy to manhandle and paddle through obstacles, though trials riding demands strong core balance and stamina from standing all day.
CharacterNimble, featherweight, and razor-responsive, this bike rewards precision throttle and body control rather than outright power or comfort.
Not Ideal ForThis is not suited to commuting, highway travel, passengers, or anyone wanting a comfortable seat and long-range fuel capacity.
