Finding information on helmets is difficult because it's so subjective. That being said, let me be the first to tell you that the Aria RX7 is the best helmet for fit, performance, and comfort. Do all the searching that you want, but, you'll find that it's pretty much tops statistically. It has variable pads that can be used to fit your noggin' properly, the best venting - bar none, the best interior padding, and it's very lightweight. It's probably a bit louder than some others but that results in it being cooler in warm weather. The price can be as high as $650. But, the Helmet Shop in Daytona Fl sells them for $450.
