EK/PBR 530MVXZ2 17/43 Chain Kit - Standard Sprocket by EK CHAIN: a transmission kit designed for 600–1100 cc roadsters. It combines the MVXZ chain with QX seals with a 17-tooth sprocket and a 43-tooth standard sprocket, effectively replacing the original chain/sprocket set to achieve precise gearing and reliable handling out of corners.
The MVXZ chain is distinguished by its lightweight holes in the side plates, large diameter pins, and QX seals designed to reduce friction. These features enhance the longevity and efficiency of the transmission: EK claims a lifespan that can reach up to 1.5 to 2 times that of a standard O-ring chain. This kit is aimed at riders looking for a high-performance OEM replacement part suitable for demanding road use.
