Kraus, RTX8 Radial Brake Caliper. Left. Black

Past op: Kraus 108mm Radial Fitments

The Kraus 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. The upgrade to radial brake calipers requires a radial caliper mounting bracket. These are separately available for a straightforward transition. Kraus or Öhlins inverted fork kits with 108mm radial caliper fitment will allow a direct installation.
OK for ABS, right?
- Includes Kraus RT-S sintered Street Pads

- Road-Legal race caliper
- Finned 2-piece caliper design for optimal heat dissipation
- CNC machined race-grade alloy billet aluminum
- 748 gram lightweight, 27% lighter than stock

*Note: Final bleeding procedure required for optimal performance.
Each caliper is pre-bled in-house, though a confirmation bleed is still necessary. Kraus incorporated an outboard bleed nipple and banjo take-off, making bleeding and installation easier while allowing fluid to fully circulate the caliper.
Note: Installation hardware is not included, See 985741 for G5 titanium radial caliper hardware kit.
