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 Bolt-Down Handlebar Adapter Mount is engineered for riders who want to run bolt-down handlebars without modifying or replacing their Sportster’s triple tree.
Precision CNC laser-cut from 1/4" steel, this adapter provides a rigid, vibration-resistant mounting surface while maintaining the integrity of the front end. A satin black powder coat finish delivers corrosion resistance and a factory-consistent appearance.
Designed specifically for Sportsters equipped with the 4-bolt handlebar clamp pattern, the adapter converts the factory setup to standard 3.5" bolt-down compatibility—eliminating the need for a full triple-tree upgrade.
On Forty-Eight models, where the speedometer is integrated into the stock clamp, a speedometer relocation kit is required. Kinetic offers multiple compatible options to complete that setup. Whether refreshing your cockpit or building a custom front end, this adapter provides a clean, strong, and efficient solution.

FAQs
Will this fit my 2016 Forty-Eight?

What handlebars will work with this?

Does it include mounting hardware?
Yes. Both top and bottom bolts are included.
Will this change front-end handling?
No. It adapts the mounting interface without affecting geometry or structure.

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.
