Product Information

KMG Carbon-Fiber Gear-Style Air Cleaner blends bold design with real performance gains for Harley-Davidson Sportsters.

Precision 3D-milled from high-strength carbon-fiber composite, the KMG’s gear-inspired cover reduces weight while improving airflow efficiency and resisting heat soak better than metal air cleaner housings.

A transparent, interchangeable lens allows real-time viewing of throttle flap movement, creating an interactive visual element for performance builds.

Internal crankcase venting removes the need for external hoses, while the included KM-378R high-flow filter delivers washable, reusable performance for long-term reliability.

Innovation Meets Passion

Made in the USA

Founded in 2013 by Mike Le, Kinetic Motorcycles was built on a simple belief: motorcycle parts aren't generic hardware — they're personal. Every product begins as an original idea, designed by Mike and developed entirely in-house.

We don't rely on templates or outsourced shortcuts. Each part is shipped by hands-on fabrication experience and time spent riding, testing, and refining. Whether you're dialing in a daily rider or building something truly your own, our focus is the same — create parts that feel intentional, functional, and worthy of your motorcycle.

What Our Customers Say

Really happy with the product. Took a while to get my order but they were out of the spark plug cables I ordered. I had to email and inquire what the deal was. They were super helpful once I initiated communication. Would have been cool to get some swag or something since they took so long. But the relocator is great. I really love it. And they responded promptly once I reached out to them. Their customer service is truly fantastic.

I had some questions on some bars, so I DMd them on Instagram. The dude I talked to was super helpful. I purchased the shirt because of his response. I’ll rep the brand due to the customer service.

Precision-machined and bolt-on perfect. Took 30 minutes to install and the difference is night and day.
