My friends son races MX and we have been having a reoccuring broblem with the front brake. FYI It has the larger front disk kit on it. The caliper slider bolts bend fairly often and part of the problem is that only one is available from the dealer. We take the pin out chuck it in the lathe and hit it with a hammer and block of wood until it is straight. Are we the only ones having this problem if not what is the fix. It has been a great bike so far. The only problems we have had is the front brake dragging and the throttle sticking.
