G'day mate ,welcome to what I call "Team Green Central".A place where you'll find all sorts of handy/interesting/useful and use
less information!
I fitted a set of ZRX footpegs, with rubber inserts, to my girls then ride an '07 ER-6,for the exact same reason,vibration. I had to give the ZRX pegs a soft run on a bench grinder for them to fit properly,didn't have to take much off. The pins fitted very easily but pegs would'nt fold all way down,hence the final shaping on the grinder.According to my girl Kerry it worked a treat.
You may be able to find something at a wreckers that fits staight up.This is what i did so if it helps ,goodoh !
I luurrve the smell of 2stroke in the mornin'.
