The Z-Racing line is based on balancing an agressive stance in accordance to your motorcycle, while keeping comfort and functionality for the rider The Z-Racing screens are designed to be more aerodynamically efficient than their stock ones, they are fully tested in the virtual wind tunnel to garantee improvements in the aerodinamic coeficient (Cx) and the aerodynamic protection to the rider Thanks to its doble height, they deflect the wind that would otherwise hit the helmet and top area of the torso In the meantime, the side channels pick up air flow and send it sideways with the objective of reducing air pressure from the riders shoulders The aerodinamic protection improvement is of 12,7 percent (on average with the upper body up) versus the original model and of 61 percent in the racing position Check compatibility with your motorcycle in the Product Description section The Z-Racing line is based on balancing an agressive stance in accordance to your motorcycle, while keeping comfort and functionality for the rider The Z-Racing screens are designed to be more aerodynamically efficient than their stock ones, they are fully tested in the virtual wind tunnel to garantee improvements in the aerodinamic coeficient (Cx) and the aerodynamic protection to the rider Thanks to its doble height, they deflect the wind that would otherwise hit the helmet and top area of the torso In the meantime, the side channels pick up air flow and send it sideways with the objective of reducing air pressure from the riders shoulders The aerodinamic protection improvement is of 12,7 percent (on average with the upper body up) versus the original model and of 61 percent in the racing position Check compatibility with your motorcycle in the Product Description section
