Anyone know what the uk laws are regarding this. Was talking to guy up the street who has an 899 Panigale with termignoni exhausts, said it sounded well and asked if he was gonna take it on track...he rekons they are registered with something like 108db standard and he could have a job passing the noise regs even with stock exhaust...crazyI know the fz1 is 95db static at 5500rpm and according to Scorpion its within 2db of this. Im not a fan noisy cans anymore and with the baffle in i find it about the same as stock in lower revs.What i dont get is that all i can find about uk rules is a figure of 80db...is that supposed to be at idle or something? I think that would be struggle for lots of stock bikes..anyone know??
Is there a noise limit on motorcycles UK?82-86 decibels is the current maximum permitted noise level for a motorcycle, the bracket depending on engine size. Most police forces use 90 decibels as the limit to take account for the effects of any wear and tear.
Mrs and I went for a walk in Upperford Copse last weekend, it's near the A32. There were many obviously large capacity bikes blatting past, clearly sporting after market cans, it was really quite unpleasant to hear. When the road noise abated it was a truly lovely and peaceful part of the world. Didn't notice any car or small capacity bike noise, just noisy big bikes.
Should anyone feel the need to buy one, Lidl will be selling Sound Level Meters next Sunday 2 Aug. They’ll be £9.99 and measure between 30 to 130 dBA, with two sampling speeds. I won’t be in a rush to get one .
Interesting the point about large capacity bikes and the lack of those 125's, could it be that the noisy 125's are mainly ragging around in the town and city and roads like the A32 perhaps longer distance biking which the 125 riders don't do - they just twat around the town round their mates houses. Also its the "full chat" I think that creates most noise - which is why you noticed the bigger bikes on the A32 and why 125s seem to be the problem around town because the 125s are at "full chat" around town (40 mph)

Not sounds.I'd be more than happy to have an Akra (or equivalent aftermarket can) that was no louder than stock just for the look.With all this Euro BS getting worse each yeah the stock exhaust are getting seriously laughable. The worst that spring to mind in the 2017+ GSXR 1000. A lovely bike that looks like someone had spray painted a kitchen bin and stuck it to the side. Its that bad that even my local Suzuki dealership do a deal where they throw in an aftermarket can when you buy a brand new one, because they know nobody likes it 🤷♂️🤷♂️

There is however several youths on completely unsilenced four stroke L-plate bikes who seem to come and go numerous times throughout the day. The bikes are deafening and they're using the throttle in such a way as to maximise the din. There's a kind of competion amongst them as to who can make the most anti-social racket.Trouble is, as far as Joe Public is concerned we all get lumped in the same bracket with them

The little shits on the small bikes even the mopeds instead of winding on the throttle they constantly yank on it going up the street, I think trying to make it sound like they have gears.

Leading on from that why do 125 riders fit loud cans?
Come to think of it what does a loud exhaust achieve that's good for anyone anywhere any time?

Thing is, aftermarket cans are bad for bikes because the exhaust system is designed to give a certain amount of back pressure. If that isn't there, hot gasses can escape from the cylinder and burn out the valves. Well there's always the "Loud Pipes Save Lives" brigade who think that it makes people notice them more (which makes as much sense as riding around with your thumb on the horn button all the time).What *really* saves lives is Defensive Riding and them not expecting everyone to get out of their way...
