Please explain Adventure?  Alex, your suggestion has caused me to think back to the mid eighties when I had a Kawasaki 750 GT.  I damaged a disc in my lower back and riding the bike was fine but any bending was or even squatting was bad news.  I know what i need said I, a ramp to run the bike up to waist hight so I can clean and work standing up.  Well by the time I'd finished I had a pretty big structure.  Twice as long as the bike including the ramp.  Getting on was a dodgey mission – take a run and hope I braked in time before running off the end. Then when I was up there I had to get off the bike and put it one the stand with only enough about a foot either side of the bike!!    I used it about 3 times before dismantling it and storing the timber for another project.  No I don't think I'll build any more ramps thanks.  😐
