Is there any type of kit that has wider ratios or a 6 speed tranny conversion for a 2011 WR450? I am a experienced desert rider and WR stock will get to only about 85 and thats pushing it wide open. I hate gearing my bikes higher because then you loose all of the low end and throttle responds. I dont need to do 100mph but at least 95 tops. My suspension is all ready set up/weight savings and all of that. Just need the bike to be purely faster.
