EK/PBR 520 MVXZ2 Chain Kit - 17/41-102: a complete chain kit designed for roadsters. This drivetrain combines the EK MVXZ chain with QX seals and a standard PBR steel sprocket (17/41, 102 links) to effectively replace the wear component of your final drive. Designed for road motorcycles, it features perforated side plates, large diameter pins, and QX seals aimed at reducing friction and limiting wear.
EK states that the MVXZ design with QX seals can offer a longer lifespan than a standard O-ring chain. This kit is aimed at riders looking for a robust replacement part for road use: leisure rides, commuting, or weekends on small roads. To ensure optimal longevity, adhere to the sprocket torque, regularly check the tension, and lubricate according to manufacturer recommendations.
Examples of compatible motorcycles: Triumph Bonneville 900 T100 (2021, 2024, 2025).
