EK/PBR 525 MVXZ2 Chain Kit - 17/45-120 - Standard Steel Sprocket
Designed for powerful roadsters and touring bikes, this EK MVXZ2 chain kit provides a robust and performance-oriented replacement solution for 525 transmissions. The MVXZ chain with QX seals reduces friction thanks to specially formulated seals, while the perforated side plates and large diameter pins lighten and strengthen the assembly for delayed wear. This kit comes with a 17-tooth sprocket, a 45-tooth sprocket (standard steel sprocket), and 120 links, with a type A rivet link.
A highly performing OEM replacement solution, the MVXZ offers a longevity claimed to be up to 1.5–2 times that of a standard O-ring chain depending on usage and maintenance. Ideal for roadsters from 600 to 1100 cm³ and compatible with models such as the BMW S 1000 R, this kit is aimed at riders concerned about the reliability and efficiency of their transmission chain. For safe installation and riveting, consult a workshop or experienced mechanic.
