The centerstand will serve as a turntable on a concrete floor, I've used it on many bikes. Standing on the left side, pull on the handlebar and bush on the seat grab bar...try it.
Oh, OK, you need a dolly thenPut a cheap plastic "cutting mat" under the center stand and it will really rotate easily... But I need to be able to push a bike sideways, in to a corner, so that "trick" won't work this time...
George, how do you get your bike onto the HF dolly? That little bit extra height would scare the bejabbers out of me. I'd be sure to drop the bike.
