KMG – Carbon-Fiber 3D-Milled Gear-Style Air Cleaner Assembly for Harley Sportster

$185.00

The KMG is a standout air cleaner assembly milled in 3D from carbon-fiber composite, featuring the iconic Kinetic gear-style cover. A transparent, interchangeable lens puts throttle flap movement on full display—an engaging blend of performance and aesthetics.

Designed for riders focused on cooler intake air, this carbon-fiber unit resists heat soak better than metal alternatives, ensuring denser air charge and improved throttle response. At just 9 ounces, it’s featherlight and sports reusable KM‑378R filter, making maintenance simple and cost-effective.

Choose your combination of finish—matte black or grey ring, hardware finishes, and lens colors—and enjoy bolt-on installation with the included gaskets and hardware. Precisely tailored to Sportster styling and build quality, the KMG enhances both the look and feel of any Iron 883, Forty-Eight, or custom cockpit.
