I don't think so. They seem to be a critter unto themselves by looking at the site in the first post. Just wondering if you had something available. I'm thinking of rear sets but don't want to hack up or drill anything.
I can't find any pics of the Tarozzis on a dual shock GPz 750, maybe one but can't be sure. If that was the right bike and pegs it looks like they bolt to the front of the passenger peg mounts.
