This brake petal cover is a possibility. I just put one on my Speedmaster and it looks pretty nice. Size is great. But it seems nothing is easy with Triumph. The opening under neath this cover and the 2 set screws are meant for a square or large rectangle pad area....Triumph's is tapered, so the set screws just barely grip. I'm still tweaking my install, so the jury is still out on this product.
