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.

Product Information
The 107 Coil is a dedicated 2-1 exhaust system engineered specifically for Milwaukee-8 Softail models.
Hand-built from 304 stainless steel and TIG-welded for structural integrity, each system is fabricated directly on a Softail chassis for precise alignment and consistent fitment.
Integrated stainless flanges eliminate reliance on OEM hardware, while the included 14 mm O2 sensor bungs provide seamless EFI compatibility across all M8 Softails.
The exhaust is internally ceramic-coated to reduce external temperature and maintain thermal stability under load.
Its modular slip-fit tip system enables riders to swap outlet styles without cutting or rewelding, making it adaptable to both solo and two-up setups.
Designed for clean visual flow and reliable performance, the 107 Coil is made to order with an approximate 4–6 week production timeline.

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.

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
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.
Customer support answered my DMs within an hour. Shipping was on point, packaging was premium.
