I bought this for my Bonneville, which leaves the rider in the wind. The helmet is very quiet, light and comfortable. It's easy to see forward when I'm tucked down on my tank as well. I got the orange, beautiful do finishes and paint. I could not be happier with the product and the price is right for the overall quality.
