Never anything that bad. You will always get a bit of pedal to shin. Went to Taunton the other night and tried a 43" sidehop, first attemp went wrong and ended up rolling off the wall head first, luckily had a helmet on and managing to roll out saved my head. Funny thing is as i thought it was safe to move my leg from the top of the wall, not realising that my bike was on top of it, the bike came down and landed o top of me. Was quite a funny one to watch though and managed to pull it off second time. lol
