520 pitch rear sprocket made in the USA of T6 7075 aluminum and made to fit Honda CR125M hubs with 8mm studs. These smaller size studs were found on the 1974 CR125M and early 1975 CR125 rear hub. Available from 49T to 57T. Larger sizes will add a few dollars to the cost. Manufacturing will take about 10 days lead time as we do not stock the 520 conversion they are made to order.
