I have shipped a lot of bikes via Forward Air (truck freight) they are a warehouse to warehouse road feeder network, safe, fast and reliable. They have special steel motorcycle shipping containers for different sized bikes. You could also ship gear etc as there is plenty of room in the containers.

They don't deliver to your door so you have to pick the bike up (and drop off) at one of their locations
