I tried to buy 2 mbx-11's at Christmas and wound up with 2 mbx-12's. Always wanted to change the forks and exhaust on both of them but got to much else going on with trying to build engines right now. Wished i could find a couple set of forks cheap for my mbx-12's , would really make a nice addition to the little bikes. Considering just making my own headers like i want them to be.
