The chrome underwind decay from National Cycle have been specially developed for the Harley Davidson FlStc models from the construction years 2014 to 2017. They offer an effective reduction in wind noise and air disturbance. These underwind deflections are ideal for being used in combination with switchblade and heavy duty windshields as well as the National Cycle Light bars. With their construction, they enable optimal distance and improve the driving experience by significantly minimizing direct air flow.
