All footpeg mounting clevises and footpeg mounts listed perform the same function. Your decision will be determined by the length required and the style you prefer.
NOTE: To measure your tube size tighten an adjustable wrench around the tube. Remove the wrench and measure the opening. Mounting Cruise Pegs off frame tubes requires 1-1/2 inch of straight open tube for clamping at equal height on both sides and approximately 3/8 inch of clearance around tube. Many mid 1990's smaller Metric engine guards were a 1 inch tube.
