I have had a pretty big off and bent my adv spec guards. They have done their job really well over two bikes and 4 years. I have never had damage to the bike with these fitted. This time though, I suspect it might be one bend too far. It was a big hit, and the left hand guard is ground down pretty flat. Was about to just go and order another set of Adv Spec when I saw the "wild at heart" bars (not to mention those adjustable rear brake levers...will be getting me some of those) http://www.wildatheartadventure.co.za/bmw800gs.html They look good, similar mounting points, 2 x cross bars, a little bit more expensive. Any feedback appreciated.
