I sold my Road King and bought my 1999 Ultra. It is intimidating due to the weight at slow speeds. I am hoping to get used to it. I would love to be as comfortable on mine as the highway patrolmen are on theirs.
I did a drop like that, but it was several years ago when I was test driving a brand new BMW K1200LT. I pulled into the dealer parking lot, had the front wheel turned just a little when I hit the front brake. The bike dove a little and upset itself, but I was over a dip in the parking lot and my foot wouldn't touch the ground. The bike went over hard enough to flip me off! My wife ran over and helped me set it up.
I was riding through the mountains in Tennessee and stopped at an overlook. A guy on an Ultra parked his bike (slightly downhill) and as he got off it began to roll forward (I have never understood the desire to park a bike in neutral). I jumped to the bike's rescue. The owner told me not to worry because the kickstand can't fold up. Another guy in an Ultra pulled up next to him, put down his kickstand, got off and the bike began to roll forward. His kickstand flipped up, the bike fell and knocked over the first bike I mentioned.
