PBR Steel Crown C45T 4671 - 525
Manufacturer reference: 4671 46 C45T
Designed for roadsters and demanding touring motorcycles, this PBR crown made of C45T steel offers a reinforced solution for the final drive. Developed in collaboration with MotoGP and Superbike teams, it combines CNC machining and targeted heat treatment for optimised tooth design and durability.
Induction hardening and tempering on the contact area ensure greater wear resistance of the teeth, resulting in a robust and reliable part for long distances. Ideal for riders seeking durability and value for money without compromise, this crown fits into the drive systems of sports bikes, roadsters, and touring machines.
Common applications (to be verified according to model and year): BMW F 900 GS Adventure (2026), BMW F 900 GS (2026), and BMW S 1000 XR (2025). Always check compatibility with your motorcycle before installation.
