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
Bold Forty-Eight Tire Lettering adds aggressive, race-inspired character to your wheels without sacrificing durability or ride quality.
Each set is handcrafted in-house from high-grade urethane that resists cracking, fading, moisture absorption, and hardening—even under prolonged road and weather exposure.
Unlike painted or vinyl alternatives, these raised letters flex naturally with the tire sidewall while maintaining sharp definition mile after mile.
Available in white or grey, with custom colors upon request, each kit includes a rim-specific placement guide for precise alignment.

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.
