For Aprilia Side Winglets The shape of the airfoils generates downforce (downward pressure) which increases stability at high speeds, helping to decrease the tendency to wheelie out of corners and at the same time increasing stability in the most decisive braking sections. Furthermore, the choice of adopting the wing type profile allows the front section to be reduced to a minimum while maintaining a high CX value (drag coefficient). Professional manufacturing, high precision and good reliability, enhance the sporty appearance and visual impact of motorcycles. Easy installation: The motorcycle spoiler is very easy to install, no drilling is required, and it can be installed in a few steps, saving time and effort, and being easy to use.
