Re: hoist recommendations for garage storage
I think you'll find that most if not all of those ready made hoist systems will have a 75 to 100 lb limit. I personally would not hang a motorized bicycle on one. In fact I use a safety strap on the one holding my wife's mountain bike and it only weighs about 35 lbs. I just don't trust that nylon rope that came with it.
For a motorbike, I'd take Joe's advice and install a couple of good quality pullys, make sure they are anchored securely in a joist or ceiling beam, some nylon rope, perferably minimum of 3/8" with at least a 150lb load limit. I tend to over build, but my stuff doesn't fall apart, or drop from the ceiling.
