Bike is home, and the dolly works. Again, thanks to Croft for the recommendation.
The ramp has an oblong-in-cross-section wedge at each end, with an attached lever. As in the photo, the lever is away from the ramp, the wedge lifts the ramp ever so slightly so that the dolly wheels leave the floor (as can be seen under the rear wheel of the ramp in the photo), and the ramp is sitting on the garage floor.
Even so, the bike is heavy enough, that on the first try, the bike just pushed the ramp forward. Only when I had my daughter stand on the opposite end of the ramp, was there enough friction to keep it from moving, and allow me to ride the bike on it. Also, having my daughter up front, she could provide minute direction to keep the front tire centered.
The height difference is minimal, and I had no problem maintaining control of the bike on the ramp.
The side piece of the ramp accommodates the kick stand. The ramp allows for five different positions of the side piece. The Rocket's wheel base is approximately 68 inches, and the kick stand is approximately 30 inches from the front, placing it forward of the middle. Even so, the next forward position for the side piece was too far, so the Rocket sits slightly back of center to make sure the kick stand rests on the side piece.
Once on the ramp, a stop bar was placed in slots behind the rear wheel (there is one stop bar at either end), the wedges were turned up, putting the wheels on the floor, and my daughter and I turned the bike 180o, just as advertised. I caution, that there is enough friction in the system, that we exercised care to not tip the bike. The key is to keep pushing and pulling low. Pushing the appropriate place with one's boot works well.
And, one of the goals of having the ramp, independent of wanting to head out, is the facility with which one may "shove" the bike against the wall leaving more useable space.
And to Tomcat's point, as much as I wish it were true, my daughter (first year with a moto license) rides the 250, and the CTX700D with its automatic transmission is a necessity in the rush-hour traffic I face in daily commuting. The timing for the Triumph is that we are approaching empty-nester status, and that will enable my wife and I to do more two-up touring.
The benefit of one of those vs a turntable is that you can just push the bike around the garage any way you want. Perfect for just spinning it around or shoving it into a corner to take up minimum space without spending half an hour maneuvering the bike back and forth on the wheels.
