Let me start out by saying I am a big fan of the Bell Star. I have the Gobert replica and am wanting a carbon version as well. The ventilation is better than any other helmet I've owned, which includes Arai Corsair V, Shoei X-11, AGV GP Tech and Shark RSR2. The helmets are notorious for fitting one size large. I wear a medium in Arai, AGV and Shark and my Medium feels a bit roomy. I've never tried on a small but I can't believe that it might actually fit. My biggest grip is the quality of the liner. Compared to the other helmets mentioned, it doesn't "feel" as plus against the skin, which I would expect in a top-of-the-line helmet. The top liner and cheek pads do fit well, but the material is not as soft as other high-end helmets. None of that keeps me from still wanting a Bell Star Carbon Speed Freak though. I would definitely buy again and recommend to a friend.
