I would not put anything smaller than a 13 tooth on the front. I run a 13X48 on my 501 and sometimes it is a little to low. In woods ridding it`s fine for me. Try a 14 first and see how you like it before doing anything else. Anything smaller than a 13 will eat the swingarm slider up, so 13 or 14 in the front. One of these should suit what you want to do and is also the least expensive way. Hope this helps.
