Precision-engineered to bring race-proven braking performance to V-Twins, the Kraus RTX8 Brake Calipers deliver superior stopping power, control, and feel—whether you're carving through the canyons, pushing limits on the track, or dealing with the unexpected on city streets. Precision-machined from race-grade billet aluminum, our calipers minimize weight. You'll experience a noticeable improvement in lever feel and feedback. Comes standard with Kraus RT-S Street pads, with optional Kraus Performance and Race pad upgrades available.

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.

Key Features

  • Better Lever Feel
  • Strong, Consistent Braking
  • Direct bolt-on for 108mm radial caliper mounts (M10 hardware, 108mm center-to-center)
  • Works with 11.5", 11.8" or oversize 320mm rotors on Kraus mounts — some combinations need rotor spacers
  • Sold as Left, Right, or a Dual set for twin-disc front ends
  • Caliper mounting hardware not included — add a Kraus radial caliper hardware kit
  • Ships with Kraus RT-S Street pads; Performance and Race compounds available
