wr and mx bikes are very very different to ride. the mx is lighter and way snappier it will go up first and fast. the wr is much heavier especially in the front end , it will go everywhere the mx bike goes but not as quick or as effortlessly. when u fall over the magic button bikes make up for the weight tho. having ridden several makes and models of both styles of tranny i would say the mx tranny is way better in almost all scenarios
