Biker's Choice Throttle Kit

Biker's Choice Throttle Kits: Clean Controls Built by Riders, for Riders

When it comes to throttle control on a V-Twin motorcycle, fit, feel, and reliability are non-negotiable. Biker's Choice has spent over five decades earning the trust of Harley-Davidson enthusiasts, and their lineup of throttle kits reflects that same dedication to craftsmanship and rider-first engineering.

A Brand Rooted in the Harley-Davidson Aftermarket

Few brands carry the V-Twin credentials that Biker's Choice does. Founded in 1971 as the New England Motor Parts Company (NEMPCO) in Massachusetts, the brand grew by following a simple philosophy: hire people who ride, and build products you'd trust on your own bike. Formally rebranded as Biker's Choice in 1998, the company has remained one of the most respected names in Harley-Davidson aftermarket parts — not because of flashy marketing, but because their products consistently deliver.

The Internal Throttle Kit: Function Meets Clean Aesthetics

The flagship throttle offering from Biker's Choice is their Internal Throttle Kit — a purpose-built solution designed to clean up the look of your handlebars without sacrificing a single degree of performance. By routing the throttle mechanism internally, this kit eliminates the external housing and cables that can clutter a custom or stripped-down build.

• High-quality components engineered for trouble-free installation and long-term operation
• Designed to work with 1" diameter handlebars, covering the most common size used on Harley-Davidson platforms
• Uses left-side grips, keeping the control layout familiar and intuitive
• Installation requires cutting 4" off the end of the handlebars — a straightforward modification for any experienced builder or shop

For riders looking for a more traditional aesthetic, Biker's Choice also offers their Pro-Era Handlebar Throttle Kit, machined from billet aluminum and available in black, chrome, or brushed aluminum finishes. This kit pairs a classic old-school hand lever assembly with a 9/16" bore master cylinder sized for single caliper use, and is engineered as a direct bolt-on for 5-speed models — making it a natural fit for custom choppers and period-correct builds alike.

Why Choose Biker's Choice for Your Throttle Upgrade?

The throttle is one of the most tactile connections between rider and machine. A sloppy or imprecise throttle kit can affect everything from low-speed maneuverability to highway roll-on response. Biker's Choice approaches this with the mindset of riders who understand what's at stake — delivering components that meet the mechanical demands of V-Twin engines while keeping the handlebar area looking intentional and refined. Whether you're building a clean custom, refreshing a tired stock setup, or chasing a specific vintage aesthetic, their throttle kits offer a proven, no-compromise solution.
