I lowered my Tenere 40mm using lust Racing lowering kit. Got my local workshop to do the work. The bike already had bar risers so the forks moved up through the yolks without hitting the bars. Chopped the side stand and rewelded. I have a centre stand and, yes, it is harder to get on the stand but if you can't manage, just roll the front and back wheels on to a couple of bits of wood to raise it, leaving a gap n the middle for the stand. Works a treat. ( you can always leave the chocks in your top box for touring).

Results: different bike. I felt doddery and top heavy on the bike before it was lowered, now I'm totally confident. The handling is unaffected except the feeling of dropping it at low speeds and manoeuvring has gone. I'm 5'8" with a 31" inside leg. I would recommend a lowering kit to anyone. You can get either 25 mm or 40mm kits from Lust racing for less than �50 on the net and the total cost for me was less than �100. Altogether worthwhile.
