Bit old thread but important one. I think i add my experience as i recently shipped my motorcycle so anyone with similar query can find out new option . I used using Citizenshipper service. They offer quiet good bike shipping service in affordable pricing. I am satisfied with their service.
One more important thing i want to tell. The packing that you want you want to do should be in such a way so that it will be protected from every aspect. If the road is not constructed properly then there are higher chances of your vehicle meeting the danger situations due to which to protect your vehicle from various accidents is important.
