Hey running biker,
I had Hepco Becker on my 08 GS. I had a misshap, and they did the job perfectly by protecting the engine. They did not bent but of course they were scratch badly, and they needed to be repainted to stop the rust. Unless you realy want the tank protection, i recommend the stainless steel one, from either BMW or Touratech for instance, they want rust as quick. The only thing is that they don't have the matching tank protetion bars.
