Default Re: how loud is 105db?

its very difficult to tell by ear just how loud a bike is, sounds daft but true.

I've heard loud race bikes that register pretty low with a sound meter. Its the type of sound, not just the perceived volume. A raspy 2 stroke 125 will register much higher than your average 4 stroke screamer.

The other thing is that the sound meter test should be done at a specific rev limit based on the bore and stroke and type of motor. Your bike might be very quiet at the test revs and loud as hell higher up.

Only way to test for sure is with a meter.
