Thanks for all the replies. Has anyone tried or seen the lock-n-load chock?
I like the idea of securing the wheel as opposed to pulling down on the suspension
Actually, pulling down on the suspension is the right way to go. Otherwise, the bike will be bouncing around like a jackrabbit and that could do a fair bit of damage to the forks and wheels. The role of the wheel chock is to simply keep the bike from rolling around and hold it vertical while you strap it down by compressing the suspension.
If you compress the suspension, the side loads are not on the wheel (motorcycle wheels do NOT resist side loads like car wheels do) but rather, they are on the straps and then the triple tree and rear shock mounts or engine guards or whatever points you have used to lash the bike on.
if you look at the physics of how two-wheeled vehicles work, the only loads on the wheels are radial (in the direction from the centre of the wheel to the tire contact patch) from the weight of the bike and when it is banked over in a corner, and tangential (as in the forces that drive the bike forward or provide the braking effect). There should be little if any side loads on a motorcycle wheel.
