The two airheads I have (R60/5 in parts, and R90/6 "dirtbike" being restored) both came with 37/11 final drives. Am I right in thinking this ratio is not ideal for highway miles (ie, dualsport) on the R90/6 (which is actually 1000cc)? What ratio drive should I look for for all-round riding (ride the highway to the trails, and then ride on the trails)? I can always keep one of these for a genuine offroad trip. And...anybody want to trade me a higher ratio drive for one of these low ones?
