EK/PBR 525 MVXZ2 Chain Kit - 17/45-120: a complete kit designed for demanding roadsters. The kit combines the EK MVXZ2 chain with QX seals with a reinforced steel rear sprocket and a 17-tooth front sprocket — equipment intended for road motorcycle transmissions (600 to 1100 cm³), ideal for engines like the BMW S 1000 R.
- Chain: EK MVXZ2 with QX seals, lightweight side plates with relief holes, large diameter pins for better resistance to stress.
- Friction reduction: QX seals designed to limit friction and wear, extending lifespan compared to a standard O-ring chain (up to 1.5 to 2× depending on usage conditions).
- Sprockets: 17-tooth front sprocket / 45-tooth rear sprocket — 120 links, pitch 525, rivet attachment for secure and durable installation.
- Material: reinforced steel rear sprocket, steel/steel finish for strength and longevity.
This chain kit is aimed at riders looking for a robust and reliable transmission for road/roadster use. Easy to install by a professional or a skilled DIYer, it offers a highly efficient OEM replacement solution without unverified technical promises — just components designed to last and transmit torque effectively.
