Seems especially weird considering motorcycles are naturally louder because the exhaust is shorter, the muffler is smaller, the engine’s exposed.
Maybe they went off of average engine size / power?
Funny thing is a smaller engine needs to rev higher to make any power. Small bikes are ridiculously loud in cities because they need so much throttle to go anywhere. A stock 50cc moped is way louder than a stock 1000cc adventure bike.
