Why would someone want to be in a motorcycle club?

Most times it's a group to gather and meet other riders for new riders, riders who like company, or riders with no friends/buddies that have motorcycles but wanna "hang with the gang".

New riders often have problems going fast enough, club/groups generally have more experienced riders heading the group and at the end of the group to lead and keep track of new riders- keep them going as fast as they should (or slow), and when it's time for a pit stop- give them riding advice to ride/turn better, smoother, faster, how to relax... etc..

Relaxing while riding is a big problem for new female riders who often ride slow like turtles =)

I also know a lot of people who like to ride in groups (part of a 'club') because they like having the "company" out on the road, and see cool stuff with... actually I know one guy who only rides if it's with some one else.

Same goes for people with no bike-riding buddies. it's a lot of fun to ride with a friend- you can find some really neat places you don't go in cars. Bluetooth helmets make it fun to converse and ride too...

there's always the safety side too- when you get into a club you get some good riding buddies with similar riding interests. Riding with a buddy can seem lame at times, but it really is a pretty good deal considering cars dont stop for riders on the side of the road- I once found a guy who got side swiped by a car and didn't stop- he broke his throttle and couldn't go anywhere; nobody stopped for him for over 30 minutes.... I guess a benefit is being able to call another club member since they wont be afraid to stop for a fellow biker.

Anyways, Those are just a few reasons, but everyone has their own personal ones in addition. It's a good social outlet, much like golfing, hockey or fishing...
