Performance Machine Caliper 137x4B Right 11.5in - Polished

This is the Performance Machine 137x4B right-side brake caliper, designed for 11.5-inch rotors and finished in a polished aluminum. Performance Machine is well-known for its high-end custom motorcycle components, and this caliper is a prime example of their attention to detail and performance focus. If you're looking to upgrade your braking system with a component that offers both improved stopping power and a distinctive custom look, this caliper is a solid choice.

The 137x4B caliper features a robust, well-built aluminum body that houses four pistons. This multi-piston design is key to its improved performance, allowing for more even pressure distribution across the brake pad and rotor surface. This translates to better modulation and a stronger, more consistent feel at the brake lever. The polished finish isn't just for looks; it's a testament to the care taken in manufacturing, providing a smooth, reflective surface that complements custom builds. While this caliper is designed for specific rotor sizes, ensuring it pairs correctly with your existing or planned setup is crucial for optimal function.

When installing a high-performance caliper like this, it's always recommended to ensure your brake lines and master cylinder are also up to the task. Upgrading these components together can unlock the full potential of the caliper and provide a more complete and responsive braking system. Refer to the manufacturer's installation instructions for specific details regarding brake line connections and mounting hardware.
