My first Mototote wheel chock got bent following a poorly controlled loading. The bike pushed on the chock and badly bent the base plate. Given the Mototote weight rating and how far forward the chock can be mounted, I would like to see a slightly stronger base plate.
A second improvement would be the design of the wheel stop. Something that pivots to facilitate loading and unloading, as well as adjustable to accomodate both 17' sport bikes and 21' dirt bike would be great.
