Bolt-Down Handlebar Adapter Mount – For Harley-Davidson Sportster with 4-Bolt Clamp

$80.00

Want to run bolt-down handlebars on your Sportster Forty-Eight or similar model without replacing the triple tree? The Kinetic Bolt-Down Handlebar Adapter Mount is your go-to solution. CNC laser-cut from 1/4" steel and powder-coated in satin black, this adapter lets you mount standard bolt-down bars directly to your OEM triple tree—eliminating the need for a costly upgrade.

With standard 3.5” mounting width and durable construction, this adapter is ideal for customizing your cockpit without compromising quality. Designed for Sportsters with a 4-bolt handlebar clamp pattern, this mount is a smart way to modernize your setup.

Important:

On the Sportster Forty-Eight, the stock speedometer is molded into the original handlebar clamp. Using this adapter will eliminate that clamp, so a speedometer relocation kit is required. Browse our Speedo Relocation Kits in the Accessories section for options.
