About this part

Product Details

Crafted from solid aluminum bar stock, this 4-piston rear brake caliper from Performance Machine represents a significant step up from stock components. Performance Machine has been a leader in CNC-machined brake calipers since 1980, and this model continues that tradition. It's designed as a direct bolt-on replacement for popular Harley-Davidson and other V-Twin models, meaning installation is straightforward without requiring extensive modifications.

The 125x4R caliper features a contrast cut finish, which highlights the machined aluminum with a unique visual appeal. This isn't just about looks, though; the robust aluminum construction and the 4-piston design work together to provide more consistent and powerful braking force compared to factory calipers. This improved stopping power can make a noticeable difference, especially when carrying extra weight or riding in varied conditions.

This caliper is intended to work with stock-style rotors, making it a convenient upgrade if you're looking to enhance your braking performance without changing your entire brake setup. When installing, always refer to the manufacturer's instructions to ensure proper caliper alignment and brake fluid bleeding for optimal performance and safety.
