As a bicyclist, loud motorcycles are the fscking worst. They're deafening and extremely distracting, which is extra terrible if anything complicated is going on. Which there often is, because people on loud bikes are often driving like fscking idiots, dodging between cars who end up nearly crowding me off the road.
I had a motorcycle pass between me and a car while I was in a bike lane. Revved his engine while he was right next to me. Scared the daylights out of me. It sounded like a bomb had gone off. Seriously, screw motorcyclists with loud pipes that drive like idiots.
The keyword is idiot, not loud pipes. To be fair sometimes we cyclists also behave like idiots on the road. Same thing when we get off our bike, get into a car and drive. Of course an idiot with a needless loud exhaust is far worse than a silent one, I agree on that.
