EK/PBR 520SRX2 Chain Kit 13/48 - ultra-light sprocket by EK CHAIN: a kit designed for cross/enduro riding where the balance between weight and durability matters. The SRX series is known for its quality-price ratio and continuous evolution; this kit retains these advantages with an ultra-light aluminum sprocket and a chain in Gold/Gold color, suitable for riders who want to lighten the transmission without adding more parts.
Designed for cross and enduro motorcycles, this kit is particularly compatible with BETA RR 450 (2009-2010) references listed among common uses. Ideal for those looking for an aesthetically distinctive chain and a lightweight sprocket while maintaining reliability in line with EK standards. To preserve longevity: regularly check tension, lubricate the chain, and inspect the condition of the sprocket teeth and the pinion after muddy or dusty sessions.
