That's not the issue, as stock exhaust note (EPA, DOT & USFS compliant) exhausts aren't the issue. It's the modified exhaust systems, which meet no standard that are the issue.
I share the same forest trails as horse riders, bicycle riders, ATVers, Jeeps and other motorcycles. We all need to cooperate for everyone to be safe and have a good time. For example: The bicycle riders need to make some noise so that they don't spook the horses, often a little bell offers the right sound. Motorcycle riders need to stop and idle as the horses pass before continuing. The slow Jeep guys move over to let the bicycles and motorcycles easily pass. We all work together, so that we all have fun.
Everyone here has been around the Harley parades with so many straight exhausts. No wonder so many so many communities are upset.
If a rider really wants more power, there are bikes that offer much more than they could ever use. For nearly the same weight as the Hyper, the KTM Super Duke offers nearly double the usable power, with the stock exhaust.
