EK/PBR 520 MVXZ2 Chain Kit - 15/43-106: a complete drive train designed for roadsters seeking robustness and longevity. This kit from EK CHAIN combines an MVXZ chain with QX seals and a reinforced steel sprocket for a reliable and uncompromising final drive.
- Brand: EK CHAIN
- Reference: MVXZ2 (520)
- Configuration: 15-tooth sprocket / 43-tooth sprocket / 106 links
- Chain pitch: 520
- Sprocket: Reinforced steel
- Quality: Super reinforced

- Attachment: Rivet (rivet installation required)
The MVXZ features lightweight side plates and large diameter pins to minimise friction losses, while the QX seals reduce wear. The result: a chain designed to last longer than a standard chain, suitable for road use and the demands of roadster riders. The reinforced steel sprocket provides torque retention and resistance to stress.
Practical advice: the rivet attachment requires a suitable tool or workshop intervention to ensure secure riveting. Compatible with several roadsters, including APRILIA TUONO 457 (2025) and APRILIA RS 457 (2024-2025), this kit is a serious option for renewing the final drive.
