Because motorcycles are relatively small compared to other vehicles, it's often easier and simpler to hire a company to transport a motorcycle. While most trucking companies will accept motorcycles for shipment, it may be worthwhile to find one that specializes in such work.
Motorcycles are more vulnerable than other vehicles to road damage, so it's best to look for a hauler who uses an enclosed rather than an open truck. Experienced bike haulers will secure your bike on its own skid and cover it within the truck.
If you are shipping a bike as part of a household move, or want extra protection, look for a "pop-up" motorcycle crate. These cost about $400 and can be assembled by one person.
