EK/JT 520SRX2 Chain Kit 13/52 - Ultra-Light Sprocket
Specifically designed for motocross, this chain kit combines a 520 SRX2 chain and an ultra-light aluminum sprocket to reduce unsprung weight without overstating unmeasured gains. Fitted with a 13-tooth front sprocket and a 52-tooth rear sprocket, it is aimed at off-road riders looking for a transmission component ready to tackle mud, jumps, and frequent acceleration.
