EK/JT 520SRX2 Chain Kit 15/48 - Ultra-Light Sprocket
Designed for motocross/enduro use, this EK SRX2 chain kit combines the durability of a 520 chain with an ultra-light aluminum sprocket. The result: a reliable transmission, suitable for aggressive trajectories and frequent changes in effort on rough terrain. The SRX series is known for its good performance-to-price ratio and benefits from regular improvements to remain effective on the track.

Regular maintenance (cleaning, lubrication, and tensioning) is recommended to preserve the longevity of the transmission during your motocross outings.
