The bike is a ktm 640 supermotard, 17's removed in place of 19" rear and 21" front. Only ridden offroad. Front forks are set for 17's in the tripple clamps(top of shock flush with clamp, ie. all the way down) How much should i move the shocks upward towards the bars without loosing stability at my top speed of 110k. Need better turning radius as well as more responsive steering. Thanks for all info that can be provided.
