The Puig Aileron Left Rearview Mirror with integrated downforce spoiler is a performance-focused accessory designed for select Kawasaki sportbikes. Manufactured by Puig and identified by manufacturer part number 21286N and vendor part number 561-21286BK, this black anodized aluminum assembly combines functional rear visibility with aerodynamic performance. Its sleek finish complements the styling of modern sportbikes while providing a durable, competition-inspired upgrade for both street and track use.
Developed with virtual wind tunnel technology and informed by Puig’s experience in MotoGP and SBK World Championship competition, the spoiler is designed to increase front-end air pressure by approximately 6.6 pounds at 155 mph. This added load can improve high-speed stability and cornering confidence, help reduce handlebar shimmies, and provide an anti-wheelie effect during hard acceleration. The spoiler’s lower section is integrated into the mirror housing to help minimize aerodynamic drag, while the mirror itself is manually adjustable for convenient positioning.
Fitment: This left-side Puig Aileron mirror fits the 2018, 2019, and 2020 Kawasaki EX400 Ninja 400, as well as the 2021 and 2022 Kawasaki Ninja ZX-10R, 2021 and 2022 Kawasaki Ninja ZX-10RR, 2023 Kawasaki Ninja ZX-10R, 2023 Kawasaki Ninja ZX-10RR, and 2024 Kawasaki Ninja ZX-10R. Verify motorcycle year, model, side, and mounting configuration before ordering. The assembly is supplied in black and is intended for riders seeking an aerodynamic mirror solution without sacrificing adjustability or sportbike styling.
