Dimensions The LED lens is 85mm wide. The rear fender is 107mm wide at the widest point, and extends 115mm below the led lights. Installation Please note that due to the integrated LED lamp on some bikes, such as the CRF-X, spacers may need to be used when mounting, and small holes may to be drilled in the rear guard. If this is the case with your model, we recommend using black bolts as these blend with the red/black trim of the CRF series. Ensure the drill bit used is sharp to ensure a clean hole.
