Shipping with the Rally is sadly less straightforward and more pricey for bikers than it is for car drivers. As it stands we can't ship bikes with cars so bikers will need to club together if they want to ship. For 2017 there are only nine bikers so this means if everyone clubbed together, it may cost quite a lot more than cars.
However, there are a few alternatives - Legendary motorcyclists of the rally have a special power - the power of lower import taxes. It's cheaper for you to import your bike into Russia than it is for cars.
Some bikers from 2016 also recommended putting the bikes on a truck to Moscow.
It would be a good idea for Bikers to join this Facebook Group. As it's useful to share plans and the such.
