The successor to the best-selling RF-1100 helmet, Shoei's latest RF-1200 is a new, next-generation design developed at the company's own state-of-the-art wind-tunnel facility. Created from Shoei's Multi-Ply Matrix AIM+ construction combining fiberglass with organic fibers, the RF-1200's shell is much more compact and aerodynamic than the RF-1100's. It's also significantly lighter too; Shoei is claiming the RF-1200 is the lightest Snell-certified helmet it has ever produced, with company reps telling us it averages about 50 to 60 grams less than the RF-1100 in the small and medium sizes and approximately 100 grams less in the larger sizes. Part of the weight reduction surely comes from the change to a rear spoiler externally fixed to the shell, instead of the molded-in spoiler shape of the RF-1100 shell. The RF-1200 comes in four shell sizes to accommodate sizing from XS to XXL. Shoei also says the RF-1200 is quieter due to its improved aerodynamics and new liner design at the helmet's base that prevents wind and other noise from penetrating that area.
