It seems like Guzzi has a long tradition of poor sidestand design
My 1000SP had the most horrible short self-folding sidestand mounted to the front of the frame. Lean angle was +25degree and the slightest push from the left would release the sidestand to fold up! I think it was the same for all tonti-frames except the floorboard models which had a Harley-like stand.
I ended up buying a used Kawasaki sidestand from ebay and making my own bracket to mount at the rear engine bolt and centre stand. It's now leaning less than 10 degree, has an ignition disable contact and does not fold up unexpectedly.
