I bought the Harbor Freight lift 7 months ago. At $300, you have to know what you are getting. That being said, I used it to lift the Rocket, no issues. Yes, it is somewhat narrow, be prepared with the handle bar straps when you start. Yes, it moves a bit, nothing major but the R3 is not light. It did the job I needed it to. I am looking at using another jack set up to place under the center of the R3 so I can remove the rear wheel. The lift has the cut out/plate in place already, I just want a secure center lift.
I switch off with the leg pump, a man needs some exercise.
