I came close recently - just got off the K3 after a good long but chilly ride and ALMOST forgot to put it on the stand! For a split-second my brain thought it was Ok to dismount and let the bike find a spot. Just caught my mind and the bike in time.
On Sunday last, I took another chilly ride and stopped in a small town 20 miles away for gas and a couple of guys on their expensive Jap tourers pulled up on the roadside opposite where there is a mobile coffee shop. They reversed their bikes up with motors running and one guy just let it go - 1300cc Suzuki went bash, crash with the motor running for a second till it cut. Heard the shrieks and explatives from the fuel pump. Broken indicator and some fairing damage. He was not happy and needed a double shot in his long black.
