Product Information

HEX Dome brings Japanese tuning-inspired design into the Sportster performance world.

The mushroom-style filter layout uses a high-flow red foam element capable of 50,000+ miles of service life when properly maintained, supporting consistent airflow and throttle response.

Its carbon fiber and nylon composite base provides superior heat resistance and impact tolerance compared to OEM plastic or traditional metal housings, reducing heat soak and maintaining intake efficiency.

An internal crankcase breather system eliminates external hoses, keeping the engine bay visually clean while maintaining proper ventilation performance.

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.
