New Moto Guzzi Door Mats Available Now
centerstands are priceless on these bikes. But for maintenance another option is a quality front wheel chock. I find that I prefer that even though I've got the centerstand. Really opens things up. Won't help if a wheels got to come off, of course, but shy of that they work well.
This is the one I use. Not as inexpensive as they used to be though.https://www.harborfreight.com/1800-lb-capacity-motorcycle-standwheel-chock-61670.htmlThe only issue with it is that it needs to be secured to the floor to get the bike out of it. Read the reviews. Some use a sheet of plywood so the weight of the bike holds it in place. I had a anchor hole in my garage floor. I use a metal rod through the chock and into the hole. Works perfect.Tom

I thought a few people made a box type adapter with two sides front and back contoured to lift the bike on the frame rails. The box gets secured to the lift and then a strap around the bike, box and lift platform. I saw it on an old old thread so maybe someone who made or used it will chime in.
