Approximately 10 years after the legendary Rf-Sr hit the streets, the Shoei Rf-Sr2 arrives to take your ride to the next level. This compact helmet retains the classic shape you love while packing in serious aerodynamic upgrades. With massively improved ventilation and the trusted Aim+ shell construction keeping you safe, the Rf-Sr2 is ready to become your new go-to. Sleeker, Sharper Design Carried over from the original Rf-Sr, the new shell features integrated upper intake lines. Out back, the top exhaust doubles as an aero spoiler, blending with the front and side character lines to deliver a sharp, aggressive look without the extra bulk. Tunnel Tested Performance Tested extensively in Shoei's 3D wind tunnel at 87 mph, the Rf-Sr2 cuts both drag and lift which means less wind resistance, less fatigue and a much smoother ride on long highway stretches. Aim+ Shell Construction Shoeis proprietary Aim+ (Advanced Integrated Matrix Plus Multi-Fiber) shell layers glass and organic fibers to deliver maximum impact strength and flexibility to keep your dome protected. Enhanced Airflow Control Like the previous Rf-Sr, this model features three intakes and two exhausts but with major upgrades. The reshaped upper intake pushes 21 more air, while the enlarged lower intake boosts flow by 43 and adds a half open setting. Both feature larger, glove friendly controls. Out back, a redesigned spoiler exhaust improves aerodynamics and increases hot air extraction by 82.
