The BRP is a beautiful ride "but" the speed limit is 45mph and since it is a federal highway speeding fines must be paid within 7 days.... Ask me how I know.
Also remember that most of the roads that the BRP crosses are great curvy mountain roads too. Do yourself a favor and get off the BRP to explore and you'll find jewels that the tourists and cops don't clutter so much.
I live within 20 minutes of the BRP and only ride it occasionally. I prefer to explore the less beaten paths.
