Hi there! Just my 2c worth: it is a grunt to heave a fully-loaded, standard-height Tenere onto the centrestand. I imagine lowering the bike by 40mm is much the same as having a nearly-flat rear tyre, and I've found that getting a loaded bike onto its stand in that situation is hernia material.

A small block of light wood of the right thickness helps heaps. Just roll the rear wheel onto it, from where it's a simple matter to use the stand. It's a bit of a pain if you have to use it every time, but it sure makes life easier.
