For day trips and round town trips, I don't carry anything. For longer, overnight trips I pack some spare plugs, a crescent wrench, plug wrench, some sockets from 8-14mm, pliers and some allen wrenches. It all fits into a really tiny fanny pack I bought for a buck and then cut off the waist strap.
After nine years and 34k miles, haven't used it yet. But its nice to know its there if I need it.
As for relying on AAA, I checked into that a couple of years ago and they said they don't support motorcycles.
So make sure you have your cell and a credit card, just in case.
But like the posters above said, you ain't gonna need it.
