I saw this posted over on the VMax site. Here is the info that was posted, FWIW.
It appears that the supplier of the lift has changed. The original lift is part number 68892. The new lift is part number 69904. The new lift is proving to be structurally unsafe. It has a main beam that is "L" shaped. The foot of the L is on the bottom. The new stop bar is a hollow tube. When the lift is lowered onto the stop bar and the weight of the load is placed against the main beam the tube bends and the main frame deforms. Down goes the load. It would do no good to replace the stop bar with one of solid steel. The main beam would still bend, even worse.
The original lift, 68892, has a "C" channel main beam and a solid steel stop bar. Much stronger. Mine is the older unit and has held Venture Royals, Royale Star Ventures, full dress Harley's, and Goldwings. It is 2 years old now with no problems.
