A high performance full-face motorcycle helmet designed for the worlds most demanding racetracks. The lightweight, aerodynamic Pure Carbon Fiber shell slices through the wind and remains stable on your head. We use 3 shell sizes to offer a perfect fit. The eye port is taller allowing you to look farther down the track when tucked-in. The optically correct face shield swaps quickly and easily using tool-less quick release technology. This race-ready 3mm flat shield comes with tear-off posts and uses the Pinlock system for the ultimate in fog resistance. The technical fabric liner is fully removable and washable. Fully adjustable flow-through ventilation allows you to stay cool. The Thunder uses a traditional “Double-D Ring” strap for a secure fit. The fit is snug, but comfortable for those long endurance races or high speed jaunts, we call it the 200 M.P.H. fit. Meets or exceeds FIM, DOT and ECE certification Meets or exceeds DOT FMVSS 218 and Snell 2020 certification.
