LEAN WITH THE BIKE
One of the most unnerving experiences for any new passenger is cornering. Many won't believe how much a bike can lean over around a corner. Avoid drastic angles of lean as this will probably scare them witless.
Ask them to lean with the bike and to relax as much as possible. Take it easy, remember your machine will handle differently with two people on board, especially if the passenger is nervous and reluctant to lean with the bike at first.
