Review RK 525ZXW Black

By: on 10 June 2025
Chain has only been on the bike for a short time. Definitely looks the business matching nicely with a new Ceracarbon rear sprocket and the existing BST wheels. Time will tell but I’ve had good mileage on my previous RK chains. RPM Moto a pleasure to deal with.
