Motorcycle Lifts
I have a motorcycle lift I purchased from Harbor Freight. You can get two options: air and a pump pedal. I store mine against the garage wall. Harbor Freight ads appear in most cycle mags and on-line.
Concerns for me: It normally takes at least two people to put the bike on the lift, one to ride it on and hold it steady while the other one ties it down.
If someone near Vero Beach, Fl wants to buy a lift, I sell mine for half price of a new one, about $250.00. I planned on setting up a motorcycle area in my backyard, patio, cover, lift, cabinets, etc. While setting up my bike area, I slipped and fell...I was able to get up about 15 minutes later.

I moved the lift into my garage and haven't used it since. That's life!
