EK/PBR 520M3 13/49-116 Chain Kit - Standard Sprocket
Designed by EK CHAIN for motocross, this chain kit includes everything needed to replace the sprocket, rear sprocket, and chain on your enduro or motocross bike. Ideal for standard off-road use, it combines a 520 chain of type M3 with a 13-tooth sprocket and a 49-tooth standard rear sprocket, delivered with 116 links.
The non-sealed design and 520 pitch prioritise quick maintenance and repairs after a muddy or dusty ride. The supplied sprocket/rear sprocket combination allows for easy length adjustment by removing links for a precise fit on your frame.
Suitable for riders looking for a reliable original fit for motocross, this kit is compatible with many models, including the BETA RX 450 4T (2024-2026). Professional installation is recommended to ensure correct chain adjustment and tension before the first ride.
