A few months ago while riding home I lost the locked cover (behind my seat) on my 2013 G650GS after going over a railroad track. I don't know why or how it came loose but it fell and broke in a couple of large pieces. I turned around to pick it up and I had high hopes that I could fix it...until I watched a semi truck drive over it and break it into dozens of tiny pieces. The locking mechanism was somehow still intact, but there was no way I could ever fix the cover. So, after a quick call to the local BMW dealership and learning that they want around $ 100 for a piece of plastic, I decided to make it myself. I am posting some pictures in case anyone else needs to make one for themselves:
