EK/PBR 525MVXZ2 Chain Kit 15/42-110 - Reinforced Sprocket
Designed for powerful roadsters, this EK MVXZ2 kit includes a 525 QX-Ring chain, a reinforced rear sprocket, and a 15-tooth front sprocket for a drivetrain ready to tackle the road. The MVXZ design focuses on lightweight side plates, large diameter pins, and QX seals which, according to the manufacturer, reduce friction and contribute to an extended lifespan (manufacturer's data: up to 1.5 to 2 times that of a standard O-ring chain).
This kit is aimed at riders looking for a quality OEM replacement, ready for sustained road riding. The reinforced sprocket offers better wear resistance, while the MVXZ2 chain minimizes friction losses for more efficient power transfer. Installation and adjustment according to manufacturer recommendations are advised.
