A well known motorcycle game is in town this week. Why do people in their 40's/50's need to be in a gang?

This is one of those times for the fraze. If I have to explain, you wouldn't understand. You clearly don't get it do you. Being in a club, has nothing to do with needing protection. Nor does it have anything to do with not being grown up. It's all about brotherhood, and motorcycles.
