Four weeks ago, the weather had finally warmed up in the mountains of New Mexico and it looked like a good day for a ride. I was on my '14 Vintage and my friends (husband and wife) drove my '18 Vintage with DMC sidecar. Late afternoon, we returned and decided to stop at the only restaurant within 20 miles of my house for dinner. The parking lot was crowded but there was available parking for the bikes in one corner. The restaurant sits high on a slope about 50 feet above the highway and the parking area is on the slope in front of the building. We parked in the available corner space and decided that the weather looked like rain clouds building quickly and maybe we should take the bikes home (only a mile away) and come back in the truck. At this time, I am parked so that I must make a right turn 180 degrees to get back to the highway. The U turn required that I pull forward, uphill, and turn right. There was plenty of space to my right side to make the turn. The pavement under me was old asphalt and I had to clear the area so that the sidecar could follow. Halfway through the turn, at about 5 MPH, the front wheel skidded on loose gravel from the deteriorating pavement. The gravel was from the asphalt and the same black/grey color and I had not seen it. There was no saving it and the bike went down on the right side. My right leg was still under the bike and my left leg still over the saddle. The engine was running. I had hit the ground on my right clavicle and the back of my head hit hard on the pavement. I was stunned but had the presence of mind to shut down the engine. I was hurt but wanted to get out from under the bike. Thankfully, my leg wasn't trapped and I was able to slip out and stand up. Two other bikers saw me go down and ran over to pick up the Vintage and put it on the side stand. I was grateful for them because my pain was bad enough that I could not have picked up the bike. 5 minutes later and after some self analysis, I knew that I had cracked a rib. No other injuries. I rode the bike home and went back later, in the truck, for dinner. Lessons learned: 58 years of motorcycle riding does not make you impervious to an accident at age 74. Front and rear crash bars kept me from being pinned under the bike. I don't care what the manufacturer calls them, they are crash bars and they are designed to protect you, not the bike. They worked perfectly and the only damage to the bike was some minor scratches on the crash bars. My Shoei helmet also worked perfectly and despite some damage to the helmet, my head is fine. Yesterday, I took the Vintage out for a 60 mile ride and life is good again.
