I hope you don’t mind my answering despite not having been in an accident. A couple of near miss situations on my ‘89 Kawasaki 305cc which was about 15 years old at the time.
1. Looking over my left shoulder as I was merging onto the freeway via the on ramp, I ended up drifting left in the process and brushed my front tire against the curbed divider. Sort of a “you’ll turn where you look” situation.
2. Driving on the freeway at night and gasping at the lane next to me which had suddenly revealed a pile of picket fence looking material that had probably fallen off a truck. I don’t know that I would have seen in it in time. I’m guessing better headlights would have helped or avoiding riding on fast, badly lit roads.
3. Driving for the first time with the former owner’s hand-me-down helmet that was too big. The wind got underneath it and blew my hair in front of my eyes. Secure your hair.
4. Driving on a two lane road and having the oncoming car make a left hand turn right in front of me. Not sure what could be done about that.
5. Driving on the same two lane road at night and having a giant stag leap across the road in front of me. Same deal.
6. Laying the bike down (always seemed to happen when I was just standing there at a dead stop) and weakening the clutch which had been bent in the process. Eventually the arm of the clutch broke off.
7. Leaving gas in the tank over the winter, which caused the tank to rust, which required a DIY acid etching of the tank and subsequent polymer coating of the tank. Chips from the polymer broke off and ended up in the carburator (I think) and got stuck under some drain valve. So basically I was driving around leaking a gasoline trail because the drain was stuck open. Fixed with an in-line fuel filter. Not sure if this would be a problem with modern bikes. Also, drain your tank when you put your bike away for the winter.
8. Traffic lights won’t recognize you (might not be a problem with a big bike). Get a car to pull up alongside you.
9. Cracks in the sidewalls of the tires. Not good.
10. Double turn lanes. Count on the jackass next to you to turn into your lane.
11. Inexperienced passengers- novices will be inclined to lean away from your turn instead of into it, which causes obvious problems. Also, if you carry a passenger, warn them not to touch the tailpipe(s) when they dismount. I made bacon out of my leg once when I rode on the back of my friend’s bike.
12. I used to flash my brights whenever there was a car ahead that was waiting to turn onto the road I was on.
13. A basic- veer to the left or right side of a lane when approaching and traveling through an intersection. Oil from cars will have accumulated in the center of the lane which can cause you to lose traction.
Have fun and good luck.
