I think I would do a combination of a couple of things mentioned above. If you have an old tire, just set the front motorcycle tire in it like a wheel chock for a little added stability. Then I would use the E-tracks and put the hooks as close to the floor as you can. Use the ratchet straps to hold down the bike. I like the straps that Shawn uses from SRK Cycles. These don't compress your shocks or forks so it is easier on your suspension with a more secure attachment.
