Klim® Yamaha F4 Helmets

The lightweight, carbon-fiber-composite Yamaha Klim® F4 Helmet is engineered to keep heat and moisture under control - even during aggressive riding - to help you focus on the task at hand. The F4 has ram air induction technology with 41 patent-pending vents, setting a new standard in ventilation technology. The ram air induction scoops not only mine air as it flows over the helmet, but helps to increase the structural integrity of the helmet. The pressure chamber network liner helps to maximize airflow over the head, while high-volume air channels allow for more air capacity inside the helmet. The F4 is also equipped with a cold weather GORE® WINDSTOPPER® liner so cold air enters the helmet without directly hitting you head while accelerating the transfer of heat and moisture out through the exhaust vents. The F4 features zonal fiber-select construction with aerospace fiberglass, carbon fiber and Kevlar®. It has a non-intrusive eye port for excellent field of vision. Includes breath deflector, replaceable cheek pads and liner, removable comfort liner, deluxe nylon carrying bag, spare visor and visor bolt. Exceeds Snell® M2000 and M2005 as well as DOT standards. Try the new Klim® F4 on you next ride and experience performance enhancing comfort like no other.
