Adjustable vertical and cross bracing to eliminate side play.  Bolt to your wheelie bars. Cross brace kits include clamps for 3/4" or 7/8" tubing, aluminum radius braces, allen bolts, hardened washers and nuts. Vertical and cross braces are included. To measure for verticals: locate the center point on the lower tube end to end, then measure from the top tube center down to the bottom tube center. Specify vertical brace length.
