Fall Riding Season is Here — Is Your Bike Ready? Fall in Colorado is a rider’s paradise. The roads open up, the weather cools down, and the views from Peak to Peak Highway or Big Thompson Canyon are unbeatable. But before you gear up for that crisp mountain cruise, it’s critical to ensure your motorcycle is road-ready. At Thunder Mountain Harley-Davidson, our Service Department provides expert motorcycle maintenance that helps Colorado riders extend the season—and avoid costly issues down the line.
