I faced a similar canundrum once, how to get a T-140 Bonneville down the outside storm cellar steps of my parent's house, so it wouldn't freeze-up & otherwise feel neglected in the backyard shed.

Moving was the easy part, I conned my Dad in helping and we used a long 2 X 12. Knowing my Dad, I am sure a suitable length of rope was somehow involved.

The problem occured when February arrived and I couldn't stand the winter silence any longer. I kicked the bike over and enjoyed hearing the exhaust bounce off the basement walls. Ooops, exhaust!! Mom wasn't happy and neither was her bridge club that evening .
