I just went for the first ride on the new gearing today!!!!! I only changed the front sprocket I still need to do the rear but I love it. I Have a 2002 Xr650L and changed the front to a 14 from a 15 and it is great!!!! I now have a lot more confidance in the bike. I went slow in first up and down several steep hills and soft sand close to my home here and it did great compaired to what it had done before. Let me know if you have a better setup.
