I hade the same thing happen in 84 when I wos working in luton, driving home from work ,pulled into the driveway( slabs/gravel centre) put the stand down and went to dismount, stand sunk into gravel and ended with a vx500 turbo on top of me for about 30 minutes until the next door neighbour got it off of me. Not nice.lucky for me the bike belonged to the honda test fleet so the cracks and scrapes were nothin to do with me.
