Kraus RTX8 Radial Brake Caliper

Precision-engineered to bring race-proven braking performance to V-Twins, the Kraus RTX8 Brake Calipers deliver superior stopping power, control, and feel. Precision-machined from race-grade billet aluminum, our calipers minimize weight. Compared to an OEM H-D front caliper, our calipers are 27% lighter. Whether you're carving through the canyons, pushing limits on the track, or dealing with the unexpected on city streets, you'll experience a noticeable improvement in lever feel and feedback. The RTX8 caliper is engineered for sustained, high-performance braking, featuring a five-bolt design that maximizes stability under load. Built for extended use, its two-piece construction integrates a finned backing to enhance heat dissipation, while four stainless steel pistons regulate thermal transfer to keep brake fluid temperatures steady. This results in unwavering stopping power and consistent performance, lap after lap, mile after mile.
