Supersprox has been a trusted name in motocross and enduro for years thanks to its extremely high quality and smart designs. This 14-tooth front sprocket is manufactured from high-grade hardened chrome-molybdenum steel (SCM440) with precision CNC machining. The special mud groove on the inside is the key advantage: mud, sand, and water are actively pushed outward, so the chain runs cleanly and experiences less wear. This results in smoother chain operation, less noise, and a noticeably longer lifespan for both the chain and sprockets.

The teeth are extra wide and feature an optimized shape for maximum chain grip, while the thickness and hardness ensure a long service life – often 2 to 3 times longer than a standard front sprocket. The sprocket comes with a sleek black or raw steel finish and fits perfectly on the original axle without modifications.
