PurposeBuilt as a full-blooded off-road and enduro competition weapon rather than a general-purpose motorcycle.
Rider FitIts tall 955mm seat height and minimal 8-litre fuel range demand a taller rider with decent fitness and off-road riding skill.

Not Ideal ForNot a good fit for riders wanting a comfortable, low-maintenance daily commuter or a passenger-friendly touring bike.
