No adjustment but I just got a set of Harris pegs, removed the folding originals but left the lugs on so you can refit the originals. Drilled a hole through and ground Two small flats on the new pegs at the right angle. The innermost round part is just to big to fit inside the lugs. when you grind the flats at the right angel and bolt them on, the flats stop the peg turning in the lug so they can't turn loos. The bolts that came with the pegs works a treat. You do have to do a small amount of grinding with a dremel on the back of the hanger to make a flat for the bolt head. I polished the hangers to match the pegs £38 I have been using them all year, I was going to get a set of rear sets but they work fine so didnt bother. Worth a try first before you lob out £200 or £300
