apart from a smoother ride and tyre availablity can anyone tell me the advantage of running 21" front and 18" rear as opposed to 19" front and a 17" rear? I have a choice of both these combinations for the TS125 and I'm near inclined to try the smaller size just to put my mind at rest. I can see advantages for both but the common size is obviously the larger wheels..As Julius Sumnermiller said..why is it so??
edit, remembering also I am extra small stature and even the new generation RM85's are way too tall for me
