Can get the front okay 300 -21 M/C 51S TT


Not the 120/80-18 for the rear. Which would be the best size option:


410 -18 M/C 66P TT reinf.
400 -18 M/C 64R TT
110/80 -18 M/C 58Q TT
120/90 -18 M/C 65R TT
140/80 -18 M/C 70R T

I'd suggest going to Continental or other sources to get dimensions of the tires of interest and measure the CRF tire for comparison. Since the CRF tire is an 80 profile, it's going to be fairly short...sadly the 120/90 may be tall by about an inch and wider. That inch can throw off your gearing...even if you are using a 13T C/S sprocket instead of the stock 14T. My opinion is too big of a rear tire just bogs little engines like the CRF
