Simple assembly, 10 minutes and it was together. I've got a RoadStar 1600, and the jack lifts the bike easily. I had a 20 year old Craftsman jack that had really seen better days. It never lowered enough to lift the Roadie, I had to hold the bike vertical till I was able to get the lift pumped up enough to start lifting the bike This jack slides right under the bike while on the side stand and immediately stabilizes the bike for the lift. It also fits under and easily lifted my VMax 1200. I've read some people commenting that the bike drops too fast when releasing the jack. Mine doesn't do that. It settles down slowly and gently. I'd buy another one, and recommend it to anyone.
