Replace the rear sprocket of your roadster with a robust and precise ESJOT sprocket. Designed for the 520 chain transmission, this steel rear sprocket features carefully machined teeth for reliable chain retention and controlled wear on the road as well as in daily use.
Whether you're cruising in the city or picking up speed on country roads, this ESJOT sprocket is designed to withstand intensive wear thanks to its high-strength steel and surface treatment. Its precise teeth limit jolts and preserve the lifespan of the chain. Ideal for roadsters and compatible with models such as the MASH FAMILY SIDE 400 (XY400B) 2019, it installs easily to restore a healthy and responsive transmission.
