Once over center, the bike will continue it's rotation around the axle. Also, compressing the bike forward puts undue stress on your front forks and neck bearings. If you are compressing the rear with the straps on the passenger pegs I just imagine the preload you are putting on the forks and bearings.

One set of straps pulling to the rear will counter this effect. Just my .02...
