I love this thread! I haven't had the CB1100 long enough to have anything to confess about, but I had the previous bikes long enough to have some "incidents." (I've also done the "oops, key still in pocket and I've got take off the gloves to fish it out" trick.)
One bike I grew to hate was the Honda ST1300, because of all the bikes I had I think I had most of my mishaps with that one. On one long trip (rode to Kansas for Hubby's family reunion) we were heading home thru Colorado, stopped at a gas station in Salida and surprisingly ran into someone I knew from a women's riding group I belonged to at that time. She was on her way home from a meet up with the group and lived nowhere near there, so it was really a coincidence. Anyway, she commented on how big the ST1300 was and wondered how I was able to handle it. I told her I hadn't had any problems handling it, it was a great bike, blah, blah. We said our goodbyes, and from the gas station we proceeded on to our hotel for the night. I immediately dropped the bike in the parking lot trying to park that big sucker. Put my foot down and stepped on some gravel, and down we went. It was doubly humiliating because of all the bragging I had just done to the friend, LOL.
The next day, taking Hwy 50 over Monarch Pass, we ran into some ice and both went down. Me on the ST and Russ on his BMW. It was a fairly slow crash but enough to bang up the bikes and bruise our egos. We had to have the bikes towed on a flatbed to the next largish town, Gunnison. The rest of the ride home I was very nervous on that bike, and it wasn't a real forgiving bike to begin with so my nervousness didn't help matters. When we got to my brother's house in Utah I almost dropped it yet again.
When we got home I told Russ, "I want a different bike."
