The Shoei RF-1100 Helmet was released for 2010 and stands squarely on the shoulders of its hugely successful predecessor the Shoei RF-1000. The new features in the Shoei RF-1100 Motorcycle Helmets are increased visibility by 5mm on each side as well as a reconfigured ventilation scheme and two more exhausts. The Shoei RF1100 Helmet also boasts a SNELL M2010 rating which its predecessor did not. Another major change on the Shoei RF1100 Helmets is the spring loaded locking system for the shield which provides a tighter seal from weather and air as well as has a 3 position setting: Locked, Open & Cracked for Defog. That is huge in our book.
