EK/PBR 520SRX2 Chain Kit 14/48 - Ultra-Light Sprocket
Designed for motocross riders seeking a reliable balance between weight and durability, this EK SRX2 chain kit combines a 520 chain with an ultra-light aluminum sprocket. Ideal for off-road sessions and muddy fields, it features a proven construction by EK CHAIN while minimizing unsprung mass for a more responsive rear wheel behavior.
Installation and maintenance remain simple: tension check, regular lubrication, and quick inspection of the sprocket teeth after rides. Cross-oriented compatibility — for example, the KTM 525 EXC Racing Factory Edition (2005). This kit is aimed at riders who want to maintain precise transmission while shedding a few grams off the rear axle.
