Complete final transmission kit by EK CHAIN, consisting of the EK 428DEH chain (non-sealed), a 14-tooth front sprocket made of PBR steel, and a 54-tooth rear sprocket made of steel (standard sprocket). Designed to replace the chain, sprocket, and rear sprocket in one operation, it is aimed at riders looking for a robust and easy-to-install solution.
Particularly suitable for YAMAHA XT 125 (1988–1990) and other 125 cc machines requiring reliable transmission. This kit provides a seamless installation between the sprocket, chain, and rear sprocket for clean torque transfer and simplified maintenance. Check tension adjustment and compatibility before installation, and regularly lubricate the chain to maximize its longevity.
