Germany is very big on noise pollution, try cutting your grass on a Sunday and see what happens. in some places on a sunday you cant even put your washing machine on. its worse than some Isles of Scotland and they are effin bonkers.

Re: Now Germany is looking at bike noise
Had to laugh!
The last line in the link regarding Austria goes "One such outcome could force manufacturers to include devices that help to silence exhausts and keep them lower so as to avoid their models being caught out." I believe they're called silencers here, or Schalldämpfer in German (literally sound damper). They'll never catch on ………………….

Re: Now Germany is looking at bike noise

Exhausts only work properly when the baffles are still in there, many remove them, including a few bikes around our way. I doubt a stock SV would trigger above 95dB so I'm OK ( not that I intend to go to Tyrol anyway ). Once again the actions of a few % who want wide open pipes are causing problems for the many who really don't want to ride around sounding like a mobile crow scarer. I am still surprised MOT does not check noise in both cars and bikes, I know some people put baffles back in for MOT, but some don't and they still seem to pass.

A stock SV exhaust will not be near 95db so you're save MOT testers do have 'some' obligation to prevent stupid exhausts, I forget the exact terminology but it appears to be open to interpretation/not a defined value as they seem to be able to use their discretion

Re: Now Germany is looking at bike noise
On my AL7, there's a sticker which states the noise level of the standard can at 4,500rpm is 77dB!

Re: Now Germany is looking at bike noise
Comparing dB levels, every 10dB doubles the noise level, so 95 is 4x as loud as 77. 95 would not be allowed in a workplace, 77 is quieter than your vacuum cleaner.

Re: Now Germany is looking at bike noise
GSXR with stock exhaust is above noise level for Castle Combe. So are quite a few other bikes stock.

Re: Now Germany is looking at bike noise
My SV kept tripping the noise meter located at the beginning of the pit wall at Brands, especially in the rain. It baffled (good pun...) the testers there for a while as they black flagged me several times believing I had taken the baffle out since they had tested me, only to find it still in place! We eventually worked out that with a K&N filter, no snorkel and the front of the tank on 10mm risers it was the intake making the noise, especially in damp more dense air. I've just adapted my line away from the wall there now and have no further issues.
