Why change sprockets all around what's wrong with stock gearing and here in the pacific north west we don't use RO we use sizes like 20" 21" 22" I have 22" haulers on mine it's what my bike came with and my buddy said he loves 22" they will pull you out of any hole and the reason I went with a +6 swing arm is cause it is a smoother ride and to keep the front end on the ground when climbing tree shots
