The EK/PBR 520SRX2 15/45 Chain Kit - standard sprocket is designed for motocross riders looking for a complete transmission ready to install. Offered by EK CHAIN, this kit combines the SRX series — known for its performance/value balance — with a standard steel sprocket, ideal for off-road use where maintenance and durability matter.
Designed for motocross machines (e.g., KTM 525 EXC Racing Factory Edition 2005), this kit facilitates the complete replacement of sprocket-sprocket-chain to restore traction precision and smooth engine behavior. To extend its lifespan, regular maintenance (appropriate cleaning and lubrication) is recommended. Suitable for riders seeking a ready-to-use solution with a distinctive golden look on the drive train.
