Complete transmission kit designed for small motorcycles and urban use. This kit combines the EK 420SH chain (with O-ring seals) with a front sprocket and a rear steel sprocket, in a 11/53 format for a ratio suitable for mopeds and small displacement bikes. Designed to replace the entire sprocket/chain/sprocket in one operation, it offers a robust and ready-to-install solution.
Kit contents: EK 420SH chain with 132 links, 11-tooth front sprocket, rear steel sprocket with 53 teeth (standard sprocket). The components are machined for precise tooth fitting and optimal compatibility with the 420 pitch. Ideal for a complete transmission maintenance before tackling the city: adjustment, mounting on the axle, and lubrication according to specifications. Check compatibility with your model before purchase.
