We ride the Black River Falls trails a couple times a year and you will see wardens and county cops riding often. They have talked to us a couple of times. They are mostly concerned with noise and safety. My Can Am runs around 104 Db and the warden said it was not load enough to be checked. They are looking for machines that are racing around the country side, making noise, and creating near misses. The straight aways we open the machines up, but over half the trail is windy, and must be ridden on with caution. A couple of people get killed every year on these trails from collisions. There are a couple of areas which you will be riding into town and through campgrounds, where the speed limit is 10MPH. The trails are some of the best we have ridden, and you have 100s of miles of trails to choose from.
