my stock supermoto gears are 15 tooth front / 41 rear...... my dirt rims i just bought the rear came with a steel 47 tooth sprocket.... if i change the 15 to a 13 in the front.... i should be able to run the same chain???? just re adjusted?? also.... ive heard some mix opnions.... but does swapping the sprockets around with the same chain mess up the wear pattern??? all will be steel sprockets... and i keep my chain like i keep my women... clean and lubed!!!!!
