you can probably drop the forks 3cm or so. same as the KLX frame. but im going to ride it first as by going from a 17 inch and 14 inch wheel setup. 12 and 12 make the front rake look good. also there is alot of room to move around the bike so getting up the front will be easy.
i have not ridden it yet. the front brakes i think will last one day then they will be glazed over and probably bin-a-ble. there are some things i want to wait for first before i put it on track so i dont wreck the bike. its my money at stake here.
Why a CR may i ask? the thing that put me off the CR's were not having a powervalve and the progressive link suspension. progressive link is good if you want the initial shock movement to be soft, but you'll have a hard time stiffening it up. there are alot of brake setups you can do with the CR's as they share the same hub as the CRF150. there are alot of CR motarded out there so im sure they are good.
if you get one then make a build thread so others in AUS can follow. you'll be doing all the hard research though.
