PBR crown made of C45 steel, designed for 520 transmissions of roadsters. Intended to replace the original part on machines such as the HONDA CB 750 HORNET (2023-2025), this 45-tooth crown features a sleek black finish and is manufactured for intensive road use. Ideal for riders looking for a robust part that is easy to install during maintenance or refurbishment of the transmission.
The C45 steel design provides good mechanical strength to withstand torque and daily stresses. The 520 compatibility makes it a direct option for many contemporary roadsters; however, please check the diameter and number of fixings before installation. A simple and reliable spare part, it easily integrates into routine maintenance operations (chain, sprocket, and crown replacement) to restore a healthy and secure transmission.
