I some bikes are too heavy to pick up, I use a car jack on the swingarm pivot and some blocks of wood to get the bike high enough then slide the crate under. Once it is on there I can rip both suspension pieces apart and go to town. The only down side, and this is true of the sears motorcycle ATV stand (I own one also and rarely use it), is that on some bikes you either have to remove the pipes or use blocks of wood to make sure the bike is on the frame and not sitting on it's pipes.
As far as AD's 175, I don't need no stinking messenger bag...I just put that biddy in my back pocket and rode over there. Seriouslt though I am the new wheelman, at least until I drop another customer bike off the lift and AD kicks my nuts into outer space.
