EK/PBR 525MVXZ2 Chain Kit 16/47 — a complete chain kit from EK CHAIN, designed for sport roadsters. This 525 setup comes with a standard sprocket (47 teeth) and a 16-tooth pinion, on an MVXZ chain with QX seals designed to reduce friction and enhance longevity. Ideal for 600–1100 cc, it is particularly aimed at compact and agile machines that require reliable transmission for road use.
