Quad bike exhaust noise limit?

[ZX7R]

I feel like a moaning old man with the query.. (probably because I am).

Now, I'm no stranger to using race exausts on motorcycles (I had one on the only one I ever owned years ago) but in our neighborhood there has been a couple of yooof racing about on some 'road-legal' quad bikes.

I can deal with the sounds emitted from motorcycle race exhuasts as I think these actually sound okay but the noise generated from the quad-bikes as they race 50+MPH down the 30MPH limit road outside is 'orrible! Yup, they max out the revs for maximum 'coolness' too. It's like someone with a vuvuzela inserted in their recturm whilst pushing out the most cronic diarrhea! It's sooo loud and nasty.

I know there is a legal requirement for sound levels on motorbike exausts but wondered if this applies to quad bikes as well?

i would say it applies to them as well. any road going vehicle will defintely have to have an exhaust fitted that mutes the engine noise suitably.

The police in our area have clamped down on motorcycles being ridden by underage riders, my local counciler takes great pride in sending out emails every time they get caught and the bike destroyed. Fills me with a ready break glow, dunno perhaps i'm getting old!
