As a newish owner I've recently had to do my first rear wheel removal. A combination of the manual lift sold on ebay(UK), a standard trolley jack and a few lumps of wood did the job, but I've got to admit it didn't feel terribly safe.
This lift looks like a very good idea for those of us who don't want to / can't / don't trust our engineering skills to make up our own brackets - a standard hydraulic lift with a purpose made bracket for the R3. Not cheap though.
Can't see anything on the site, but I'm guessing it's some kind of castor wheel kit that fits to the stand so you can move the stand and bike around when the bike's lifted.
