Some of the attractions of a motorcycle are its sights, sounds, and vibrations. You're connected to the thing more so than you are in your average car—supercars aren't average, btw—and you feel as if you're a part of the machine. You're exposed to all those senses, and that's why a lot of us ride. To feel something out of the ordinary.
Yet, in the oncoming electric revolution, the sights may stick around, but the sounds and the little chatter and movement from an internal combustion engine are dead on arrival. EVs don't vibrate. They don't sound like anything outside of the EV motor's whir or the slap of a chain on the bike's sprockets. And the latter may not be around at all, as belts and shafts have been favored by some electric motorcycle manufacturers.
Yamaha, however, doesn't want to lose those quintessential motorcycle attributes when it finally goes electric. The company wants an EV motorcycle that feels and sounds like one powered by ground-up dinosaurs. It wants an EV motorcycle to feel like a motorcycle, which is why it's just patented that very concept.
