the one with independant front suspension is the best one im gonna have to say. i have this one and i can fit the pro jet pipe along with a stock cag pipe and prolly even more!
the ones with the single front shock dont really fit any of these pipes not even the rev unlimited pipe. and the ones without suspension were made for the street they're the closets to the real blata quadard and even in the blata manual it says for smooth surfaces only.
if i were you i'd be looking for one on
ebay! that way you can see what they're gonna send you. you get what they give you from minipocketrockets and pbu is just a rip off have you checked how much shipping will be with them? also those minipocketrocket parts are too expensive and they're the same chinese parts sold everywhere else.
so you should be looking for the one with 2 front shocks you'll be able to fit a nice pipe, carb etc.. and the little control arms are pretty kewl!
