i dont know yet i bought the one out of my old bike for 100 bucks if it will fit i minght . i never really mxed the auto clutch just woods racin i dont know how it would act over some bigger jumps…and i am kind of sceptical on using the rear brake in the air cause it would throw it into neutral i usually have to do alot of correcting when i am in the air (lol) but they sure do knock down the arm pump…
