I have a 2003 CRF 450 and I am wanting to convert it a little so I can do some woods riding. I am thinkking about going from a 50 to a 53 tooth sprocket in the back. The front is 13 stock. I have been told not to go any smaller than that on the front because of high chain wear. True or not? Also, if I go to a 53 tooth on the year, how much longer will my chain have to be? Thanks
