I think they look cool on some bikes, but I've never seen any I liked for XBs. I think the stock pegs/brackets fit the lines of the bike perfectly. I also don't have any issues with grinding pegs on the street, so my pegs work fine. I did remove the stock feelers and replace them with shorter bolts, so I at least gained some ground clearance that way. If I wanted higher pegs I can always just trade to some firebolt pegs(I have a lightning now).
Also, there's a ton of stuff I could buy for my bike with $3-500 that would have more benefit than moving my footpegs an inch.
