I would think that a m/c would not be much different than lawnmowers, snowblowers etc. Just drain all fuel. Are the m/c's the only thing being moved ?? If so, having used a ReloCube, they just might fit. Either way, would suggest padding them with used mattresses or similar. And good tie downs.
To be sure of above, just give them a call. Nice people at the 800#
