This SXS 300 kit is made for enduro 250 XC and XC-W. This kit includes all the parts required for converting your 250 XC/XC-W to a 300 XC : a new cylinder, head, piston, rings, wrist pin, gaskets, clips, o-rings, power-valve parts and black box. It is smoother and easier to ride because of its lower compression and a different black-box map. No need for the jets to be changed on the 250 SX carburetor.
