Spoilers D12. The new D12 spoiler line by Puig has been created with a clear goal: to put aerodynamics above all else. These side spoilers have been developed to deliver maximum aerodynamic performance on high-performance motorcycles. The innovative double-wing design, with separate surfaces divided by a lateral spoiler, channels airflow upwards, generating greater downforce without compromising the overall aerodynamic coefficient. The angle of the surfaces has been carefully studied to offer an optimal balance between performance and stability without significantly penalizing the bike’s drag coefficient (Cx). Thanks to the design of its surfaces and the separation between them, Puig has created its most efficient wing to date.
