EK/PBR 525 SRX2 Chain Kit - 16/42-108: a transmission kit designed for riders who want a robust and reliable part to replace their worn chain. The SRX2 series from EK CHAIN is known for its good balance between performance and price, and is particularly suitable for mid-range roadster and sports bikes.
Designed to withstand daily road use — rides, commutes, and more intense sessions — this kit combines a reinforced chain and a standard steel sprocket to ensure a solid interface between the sprocket and rear wheel. The installation is done via rivet attachment, a common process for a durable fix. Check the length and number of links to adapt the cut to your bike's swingarm.
Common compatibilities: suitable for YAMAHA R7 (2023, 2024, 2025) and other roadsters using the 525/108 pitch. Ideal for riders looking for a simple, robust drive part that meets EK CHAIN standards.
