The LS2 Fast MX, Off Road Motorcycle Helmet – Buin in LS2’s own factory, and perhaps the best value in a lightweight motocross helmet, the Fast is a technically advanced weapon for serious off road riders. The shell is made from LS2’s proprietary Kinetic Polymer Alloy (KPA). This innovative material is ultra-light weight and offers a bit of energy absorbing flexibility, but with a penetration resistance that rivals high-end composites. The wide eye port accommodates most major brands of goggles. Intake and exhaust ports ensure plenty of ventilation to keep you cool, whether during a long moto, an endure, or a long day on the trail. 3 shell sizes and a reinforced double D-ring chin strap makes for secure, comfortable fit. A multi-density EPS safety liner offers state-of-the-art energy absorption. The Fast uses LS2’s Emergency Release System cheek pads, making it easier to remove the cheek pads if a rider takes a serious fall. The cheek pads are contour cut out of high quality foam using LS2’s 3D laser technology for all day comfort. The comfort padding uses a technical fabric that is breathable, hypoallergenic, and is fully removable and washable. LS2 designers worked with professional riders from Dakar, World Enduro and motocross to build a pro-level product at an affordable price. The Fast offers everything you need in an off-road helmet, whether for MX, Enduro, Trail or UTV, at a price that will stun you.
