The EK/PBR 520SRX2 14/48 - ultra-light sprocket kit is designed for off-road riders seeking a reliable and lightweight transmission for their motocross sessions. Coming from the SRX series, this kit offers a balance between durability and cost of use, without technical exaggeration: a gold-finished 520 chain paired with an ultra-light aluminum sprocket to minimize unsprung weight without compromising assembly quality.
