Sprocket ZF Sprocket Sherco SE 125 2T year 18-22 / SM 125 4T from year 23 onwards, pitch: 520/50, various colors Colors

The ZF dual sprocket with 50 teeth and 520 pitch is one of the highest quality sprockets for sporty enduro, cross, and supermoto applications. The combination of an extremely wear-resistant steel ring gear and a lightweight duralumin core ensures high durability while significantly reducing weight.

The duralumin alloy used offers very high strength and, when hardened, achieves almost the same stability as steel. This makes the sprocket around three times more durable than pure aluminum sprockets and at the same time around 50% lighter than conventional steel sprockets.

Milled pockets in the tooth base ensure effective self-cleaning. Dirt, sand, and mud cannot accumulate, which significantly reduces wear on the chain and sprocket. This makes the ZF Dual sprocket ideal for tough off-road conditions as well as sporty road use.
