I make a footpeg widener as well, $27.50
Allthough they can look a bit tacky welded around the originals so I also make them with a centre piece, so you can cut the serrated part of the peg off the mounting bracket & weld these in their place.
Once painted they look normal except they are 44mm wide.
$44.00
The trouble is some of those Suzuki pegs are some sort of cast item so you can't really cut the old serrated bit off.
