Many people aren’t familiar with deer whistles, or haven’t tried them. Two years ago, I happened to hit a deer with my C-10. Luckily, it was a small deer, and I didn’t centerpunch it. It hit on the left side, and my tip-over bars prevented a lot of damage to the bike and me. Since then, I have been running with deer whistles mounted on the reflectors on the sides of the fairing, and they definitely work! Not only have I not had anymore close encounters with deer, but other animals get off the road long before I get to them. Birds of all sizes hear them from far off, and get out of the way as well. I’m sure I miss seeing some wildlife, other than tail ends going into the woods way ahead of me, but I don’t mind. One of the best safety features you can add to your bike.
