Protecting your head should never be a consideration. Shoei has constructed the RF 1000 to be efficient through the winds while providing the best protection possible. Fit and protection are hand in hand because, if the helmet is moving around, it’s not doing its job. 4 shell sizes and 5 different pad sizes help customize a proper fit to just about any head size. The pad system is dual layered to aid airflow from the outer vents to your head. Each shell has AIM construction to lighten the shell, keeping weight down but it still disperses impact energy to reduce head trauma. An often overlooked feature is the shield. Shoei helmets employ a standard CX 1V shield which is used on most of Shoei’s line. Use you head to take care of your head with the RF 1000.
