LS2 Thunder Racing 1 Matt HV Yellow Full Face Motorcycle Helmet. The LS2 Thunder Racing 1 Helmet was designed by a team including engineers in Spain and LS2 riders from Moto 3, Moto 2, WSBK, and FIM EWC. The lightweight, aerodynamic Pure Carbon Fiber shell slices through the wind and remains stable on your head. The eye port is tall and extra-wide, so you have a maximum vision in the front and on the sides while riding. The 3mm face shield is race-ready and comes with tear-off posts and uses the Pinlock system for the ultimate in fog resistance. The Emergency Quick Release System removable cheek pads are precision cut from one solid piece of high-quality foam using LS2s 3D Laser Technology. To ensure you are dry and comfortable while riding, the moisture-wicking fabric liner is removable, washable and the fully adjustable flow-through ventilation allows you to stay cool.
