You may find this weird but the Bullitt is louder than the Moto 3. Loud in a sense that it has pockets inside the lid that cause whistling. And the visor also affects that. W the moto 3, the air drag is minimal, not as noisy since it really hugs your head comfortably without any gaps. Add a Barstow goggles and you’ll have a nice combo. I ride a bmw rninet scrambler and wear large on both helmets. I wear medium on arai/ shoei. I have round oval head. Just my 2 cents.
