You see how they countersunk the stud. It is only about 3/16 maybe a 1/4 thick at most. My Honda and Suzuki are about twice that thickness. The track we were on the biggest jump is supposed to be 70 ft and several 20 to 30 ft. I'm just glad it broke in a corner. I could not ask for better service though. New hub and wheel (which looks fine to me) are on the way.
