Hi All,

I've just been to a noise test at Castle Combe and my GSXR 1000 K5 with Akro pipe (baffle in) passed. It ready 103db at 10k RPM.

I think this is pretty close to what my cheapy noise tester showed.


Was pretty painless, just emailed them, they came though with dates and times and arranged a slot.

Might actually book a session now.

Cheers

10000rpm!!!!

bloody hell, they only do it to 7500 at cadwell

Yeah I thought it was a bit high. Been much lower down the scale when I had it tested elsewhere.

A 1000 would be asked to rev to 5500 for an ACU noise test, a 600 has to rev to 7000.
To appease the local noise nazis, Combe test to ¾ maximum revs, so on a modern 600 revving to 16k, it has to be held at 12k for the noise test..

What Scotty said.
They are governed by NIMBY’s in the village that have had the council imposed planning restraints (like Pembrey, Thruxton and Donington, to name a few) and not ACU regs. It’s only ACU regs under a licenced event.
