I crashed pretty hard today, and the R&Gs did an excellent job. I got away with a little fairing rash, a bent brake pedal, a trashed helmet, and a sore butt. I'll definitely be getting another set, didn't even touch the bar end, and the tab on the fairing is still in tact. The bolt on the front right fairing slider is bent almost 90 degrees, but the brackets are untouched. I'm pretty sure any other sliders would have saved some of the bike but not to the extent that the R&Gs did.
Sorry for the crappy cell pictures.
