Works Connection foot peg wideners. Cheap and easy. I welded them to gain 1.25". What a difference! I was riding with my feet turned in before, now I have more room to move around.
I see that you welded yours on so that they extend further out from the peg (perpendicular to the bike). The WC webpage shows to weld them along the sides and at the tip, effectively not making them any longer. Do they still feel plenty strong the way you chose to do it?
