This kit is particularly suitable for HUSQVARNA CR 125 models (2011–2013) but may fit other machines equipped with a 520 pitch and a 13/50 tooth count — please check compatibility before purchase. Aesthetically pleasing and clear in its off-road orientation, it finds its place on cross bikes that require a quick transmission replacement.

Practical tips: check the tension and wear of the chain after installation, lubricate regularly, and tighten according to the manufacturer's recommendations. For optimal installation, consult a professional if you are not equipped.
