These highway pegs utilize our unique offset mount to allow riders a range of adjustment not possible with other clamp-on style highway pegs. The offset can be rotated 360?? in a 4 diameter circle to accommodate tall, short, or average height riders. These can be installed on any round tubing (frames or engine guards), but it is important to keep in mind that the footpeg itself will end up perpendicular to the bar to which it is mounted. If your engine guard is angled in such a way that the peg will not be level once installed, look to our Right Angle Mounts or Male Adapters with Adjustable Stop
