EK/PBR 520MRD7 Chain Kit 14/48 - Ultra-light Sprocket
Specifically designed for the motocross world, this EK CHAIN kit combines a high-performance 520 chain with a 14-tooth sprocket and an ultra-light 48-tooth aluminum rear sprocket. Gold finish on the chain for a polished look and increased abrasion resistance. Designed for riders seeking reliability and lightweight performance without compromising strength.
The combination of the 520 chain and aluminum sprocket reduces rotating mass compared to traditional steel sets, which can contribute to a more responsive feel at the rear. The EK construction focuses on good tensile strength and abrasion resistance to keep pace with motocross outings and intensive sessions on loose or rocky terrain.
Common compatibility (examples): YAMAHA YZ 450 F (CJ05) 2004, YAMAHA YZ 450 F (CJ03) 2003. Check the number of teeth or the length required for your motorcycle before installation.
