NS400R too loud
Posted: Mon Mar 27, 2017 8:34 am
Today I had the registration check with my NS400R (German bike, so it needs a special check).
Everything fine - just too loud with standard exhaust.
103dB@4500rpm
More or less what I have expected, it was quite loud during the test ride yesterday
No registration in Austria until I have solved this issue (95dB is allowed)
As far as I know this is a standard problem of the NS400R.
Anyone here who has already disassembled some stock NS400R exhausts?
Is it necessary to cut them to open it?
Which technology are they? Resonance dampers or absorption dampers?
What`s the reason why they get so loud?
How can I get them a bit more silent (at least for the check)?
After the check nobody will care about it...
