IIRC only one bolt and loosen the other one.
My Lemans 4 is undergoing a race bike conversion (land speed racer). There is no fender behind the saddle/frame. Pulling the wheel straight back is no issue. I regularly pull the rear drives to change gearing, etc, so grease is not an issue. Currently I'm running a 110/90-18 rear tire (narrower/smaller diameter than the stock 130/80) on the 3" rear rim. Getting it out is not an issue. I also run short shocks to lower the bike, so the tire is already pretty high in the air when on the center stand (which will be removed for racing). Of course removing the 2 bolts holding the caliper on is easy, I just prefer to be able to pull the rear wheel with only having to take off the axle nut and loosening the pinch. Spoiled I guess...
I know of several guys who take the rear drive off their Tontis when they take the wheel off.Then it's a trivial matter to grease the drive shaft splines at the same time.
