Scooter Scooters Motorcycles

Is there any motorcycles or scooters enthusiasts out there who can help?
I am looking for group biking rules such as formation of bikes while riding, signals to be used and things that should be avoided during the rides.
Useful information on motorcycle group riding
A Group Ride is normally composed of a Ride Leader and a Sweep or Drag Rider (bringing up the rear). For organized rides they usually have Radio or CB communication and knowledge of the route including not only the final destination, but also the stops along the route. If more riders in the group have radios, then casual chatter during the ride should be kept to a minimum by the riders of the group so that the Lead and the Sweep Riders can be in instant communication whenever needed.
