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.
