Yep, done it after parking in a hurry, kicked the sidestand down and swung my leg over, next thing I know me and the bike are on the floor like a pair of dominoes because the stand sprung back. Bent clip on and a snapped lever end
Stopped in the Pyrenees to take a picture, I put the stand down but the camber of the road flipped it up and I ended up under the bike (good view though)
Ouch. i did the same thing on my 2019 R1 at Donington. pulled into the pit garage, flicked the stand down but it wasn't down and just fell off in front of everyone
