I've had master links come of since the 70's as a kid. I use them and carry spare. Out of the blue one came off in a desert race out at Red Mtn and had to get a super nice racer to stop and give me his. I did spend time driving around the pits to return the favor. I did buy rivet style plus the install too for my new cross nation 701 husky. It came with one is a sign that 75 hp needs them. I went to a 48 from 46 tooth rear sprocket. The big benefit also besides the crushed head is the pin to link plate is interference fit. Very strong.
