I use a standard floor jack and a piece of 2X4, then slip this little beauty underneath the crossbar on my 72 CB750, and I can lower and have full access to the front end, a one person job.
The 45 degree cut out of the top of the 2X4 is 25 1/2 inches off of the ground (bottom of v) which includes the 1/2 plywood base. I take no credit, somebody here had posted something similar.
