EK/JT 520M3 13/52 Chain Kit - Ultra-Light Sprocket by EK CHAIN: a complete kit including chain + 13-tooth sprocket + 52-tooth sprocket designed for motocross. Built to withstand off-road conditions, it combines a robust 520M3 chain with an ultra-light aluminum sprocket to reduce unsprung weight without making exaggerated technical claims.
This kit is aimed at motocross riders looking for a reliable transmission, with a good compromise between abrasion resistance and reduced friction. The golden hue provides a polished finish and facilitates visual inspection during maintenance. The 13/52 setup is common on 125cc motocross bikes; this kit is particularly compatible with HONDA CR 125 R (JE01) models from 2001 to 2003.
Installation and adjustment: adhere to the torque and tension specifications recommended by the manufacturer, regularly check the chain guide and tensioners after the first rides in muddy or sandy terrain. This EK CHAIN kit is suitable for intensive motocross use while remaining easy to maintain on the track.
