d-links are over rated, the linkage are nothing like mx or nowhere near as smooth, if you got one i would change linkage block to a lxr linkage,
i've had every style of pit bike going and by far my favourite is the klx style pit bikes, ie, the pitster pro x4r and kzr and the crf70 bikes, the xlr and ssr of course both with sp forks and decent shock, i think those 2 handle the best an i progress the most when i had the klx style kzr and x4r, hence why i am going back to a klx pitster pro x4r
