On the related topic, you know how in Ford Mustang the engine noise is simulated so the engine would sound like a pre-emission-standards V8 even if it runs on just four? How about a similar thing for a motorcycle? You put on your noise-canceling head phones, and the phones emit a "noise-canceled" rev of an engine you choose. You can enjoy the sound of a Harley on a moped. And! Since it's your headphones only, you wouldn't even bother the public.
I think there is a startup potential on it somewhere. And the technology is here too: https://github.com/ange-yaghi/engine-sim
So one way or the other, you're going to lose most surrounding noise. Might as well listen to some music while you do it, if anything because riding with music is THE BEST FEELING EVER.
I did notice today that the shorty levers I installed on my Honda only give me three fingers of leverage instead of four like this video was talking about - I'm going to have to see how much that affects my left-hand endurance.
