I have an 86 Airhead and a R1200GS and I was considering a Kendon lift due to it's portability. Unfortunately, it doesn't support the use of the center stand. Kendon expects you to lift the rear wheel with a scissors jack. It doesn't look to me like either bike has frame tubes accessible to a scissors jack and the other "stuff" under the bike does not look like it is sturdy enough to support the weight of the bike. What sayest the collective experience?
