Product Information

HEX redefines Sportster intake architecture with a seamless one-piece extruded structure.

Unlike traditional milled components, the HEX is produced using 3D extrusion, creating a solid, uninterrupted airflow path that improves strength, thermal performance, and flow efficiency.

The carbon fiber and nylon composite construction resists heat soak and impact stress while remaining lightweight, making it suitable for both daily riding and high-performance builds.

Integrated internal crankcase breather chambers eliminate external hoses, maintaining a clean engine bay appearance while supporting proper ventilation and airflow stability.

FAQs
Is HEX a full intake system?

No. It is a velocity stack with an integrated breather system, not a full manifold.

Does it require external breather hoses?

No. The internal breather chambers eliminate external lines.

Can I customize the colors?

Yes. Mesh, housing, base, and hardware color options are available.

Is it compatible with a 2006 Nightster?

Yes. Compatible with all 2004+ Sportster models.

What advantage does extrusion provide?

The one-piece extruded structure allows smoother airflow paths and integrated internal breather chambers that milled parts cannot achieve.

Designed & Built in the USA

Every Kinetic product is designed and manufactured in the United States. Keeping our work in-house allows us to control quality, refine fitment, and stand behind every part we make.

A Decade of Hands-On Experience

Founded in 2013. A decade of machining, installing, riding and refining components on real bikes — not just in a lab. That experience shows in the quality of every part we ship.

Designed by Riders & Builders

Every product is shaped by hands-on building and riding experience, with practical decisions made where it matters most.

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.
