i've heard that 400ex a-arms will bolt right onto a 250x(same as 300ex) frame w/o any modifications to the frame components....is this true, and how big of a handling improvement is it over stock form?? also, i would like to know if i did this wat type of shocks would i need to get to have the best performance with the new a-arms?? i am hoping for this to be a big improvement b/c i am a very aggressive trail rider, and i need to be able to haul a$$ around the woods, so i need this change!! any help will do, so thanks in advance for the posts.
