Product Details

What you get with this Performance Machine 125X4B caliper is a single, chrome-finished brake caliper designed to work with 11.8-inch (300mm) discs. This caliper is made in the USA and is built to offer a noticeable improvement in your motorcycle's braking performance. It's a solid option for riders looking to upgrade from their stock braking system, providing more consistent stopping power and a sharper feel at the lever.

This caliper is a direct fit for a wide range of Harley-Davidson models, including popular bikes like the Street Glide, Road King, and various Softail and Sportster variants. The chrome finish not only looks sharp but is also a durable coating that helps protect the caliper from the elements. Performance Machine is known for making well-built components, and this caliper is no exception, featuring robust construction that can handle the demands of regular riding and spirited use. When you're upgrading your braking system, choosing a caliper that offers both reliable performance and a clean aesthetic is key, and this model aims to deliver on both fronts.

When installing a new caliper, it's always a good idea to inspect your brake lines and rotor for wear. If your brake fluid is due for a change, now would be the perfect time to do that as well. This caliper is designed to be a direct replacement for many stock calipers, making the installation process straightforward for those comfortable with basic motorcycle maintenance.
