Diffuser Extention-2 (DF-X2) Spoiler Frost Black

Designed to ‘fill-in’ and smooth the aerodynamic flow between the helmet and the rider’s suit hump. In keeping with Arai’s core belief that a Strong, Round & Smooth shell helps to increase a helmets ability to protect the rider during an impact, the Diffuser Extention-2 is designed to be frangible and to crush or breakaway easily upon impact. Made as thin and light as possible, this aerodynamic add-on improves highspeed stability and increases ventilation without compromise to impact performance.
