Motorcycle Sound Measurement Training Class & Muffler Outreach

By | February 13, 2015

As we all know, motorcycle sound has become an issue that must be addressed.  Loud motorcycles give the non-OHV public a reason to complain and more to the point, a reason for some to call for ousting motorcycles from our already established  riding areas, both on public and private land.

Here is an opportunity, at no cost to you, to get involved with learning how to control sound and receive a certificate that shows you have been trained to do sound testing.  Note that space is limited so call now to get your seat in the training class outlined below.
