My chain and sprockets dont have a whole lot of time left and I was going to regear. Right now I have 13/48 and its great at low speed, but the top end sucks. I frequently find myself wishing I didnt have to row the gears as much and also wishing for a 6th(my XR250L had one and I'm glad). I do alot of desert road/double/single track and a fair bot of forestry riding. I was thinking at least a 14t countershaft. What do you all recommend?
