Well I just installed a set of GBC x-rex tires(20x11x10rear and 21x7x10front) on my XX! Just wondering what set-up everyone with 20" rears are running with they're sprockets?? I dropped one tooth on the front when I was running my stockers, which is still whats on there now!! I havent got enough seat time yet to determine a opinion on this set-up with the 20s!! I mostly just trail ride with some occasional drag races!! So whats everyone running and how yall like it???
