Europe has fairly strict sound limits on motorcycles (and they are getting stricter) in euro4/euro5. This constrains the manufacturers, but aftermarket enforcement really varies by location.
These days a lot of manufacturers homologate to meet multiple standards, so we get euro4ish stuff in north america too, stock at least.
- andrepd 7y agoYep, it's not so much the production limits (still, they could be pushed gradually lower and I'm sure the manufacturers would manage), but it's the often grey-are of aftermarket modifications.

- ska 7y agoI suspect you meant engineered to be quieter? Excluding intentionally loud exhausts, the intake on a lot of bikes generates more sound than the pipes, at least at speed.
