TP I have a set of Rizoma clip ons in the garage that have been fitted but never used. They weren't right for me. They'll fit a 620 but not a 600 monster. You can give them a go if you want. I'd post a picture here but I don't know how. If you go to
www.rizoma.com and look for part code PA202D you'll be able to see what they look like. It's up to you.
Cheers,
Doug
