Ouch that's a gixxer too. I just took mine off yesterday because they seemed crappy.
Had to cut the piece of crap off just to get at the bolt and now I need new engine bolts too.
Thanks for the warning. I will not be installing new ones on the GSXR.
All my low speed ninja 250r tips frame sliders helped but not with my only high speed crash. I think they may have helped do more damage but I'm not sure, I was not watching the bike while sliding across the asphalt.
