520 X-Ring Chain and Sprocket Kit

The Vortex 520 Conversion Chain & Sprocket Kit offers a customizable and lightweight upgrade for the BMW S1000RR models from 2009-2014. This kit is ideal for riders seeking enhanced performance, particularly for track use, by replacing stock components with narrower and lighter alternatives. Each kit includes a durable Vortex chromoly steel front sprocket, a choice of a Vortex black steel or aluminum rear sprocket, and a premium 520 X-Ring chain from brands like EK, RK, or DID. The chain is pre-cut to the optimal length for your specific motorcycle and selected sprocket sizes, and comes with a rivet-style master link for secure connection. This kit is compatible with all 2010-2018 S1000RR models equipped with standard wheels. However, it is explicitly stated that this kit DOES NOT FIT models with the optional FORGED or HP4 wheels. While the chain is pre-cut, it's recommended to always check the chain length before riveting the master link, as some minor adjustments may be needed due to variations in gearing, tire sizes, or wheelbase.
