We may or may not have had the opportunity to ride in a group, but here area few basic guidelines everyone should learn about group riding, but like all things two wheels none of these are hard and fast so ride your own ride.
Group Riding: Lane Positions
Single-File or Stagger?
When riding in a group, the group's formation should be dynamic, but should follow a few basic guidelines. If the road is straight and there are no unusual traffic or surface conditions, the staggered riding formation allows a proper space cushion between motorcycles so that each rider has enough time and space to maneuver and to react to hazards, while keeping the group compact. The leader should ride in the left third of the lane, while the next rider stays at least one second behind in the right third of the lane; the rest of the group follows the same pattern. (See diagram.) If the group is using this pattern, the leader should remain in the left position, even after the group changes lanes, so the other riders aren't continually changing their positions in response.
However, if the leader feels that the center third or right third of the lane is the best position for the conditions, then the leader can signal the group to adjust to a single-file formation, with a 2-second following distance throughout. MSF recommends that a single-file formation be used on a curvy road, under conditions of poor visibility or poor road surfaces, entering/leaving highways, or other situations where an increased space cushion or maneuvering room is needed.
