Ratchet straps are key. They don't tend to loosen up. As well, avoid strapping down to your racks. As the bike boucnes during transport it will cause it too lossen up. What are you using to transport your quad? trailer or truck?
Always tie down to the frame at the lowest point possible and then to a low point on the trailer/truckbed. The flatter the angle the more secure it will stay. If you are on a trailer do this at all four corners and it won't move.
In my truck, The front of the quad is pushed tight against the forward part of my truck bed. Then I take a strap and it around the rear tires and off to the eye hooks that are set low on the bed of my truck. I get picks if you need.
