The EK CHAIN 525ZVX3 15/40 chain kit is a transmission set designed for riders seeking durability and aesthetics. The ZVX series from EK features high-strength chains intended for large displacement motorcycles; here it is paired with a hardened Ergal sprocket for an optimal weight/strength compromise suitable for powerful roadsters. The gold finish on the chain and rivets adds a racing touch without compromising on appearance.
This kit is aimed at riders who want a transmission ready to withstand high demands while maintaining a polished look on the motorcycle. Compatible with many high-displacement sports and roadster bikes, it is easy to install as a replacement for the original when the fitting is compliant (15/40 sprocket/chain ratio provided). Examples of compatible motorcycles: MV AGUSTA F4 1078 RR 312 (2009‑2011).
Choose this kit for a high-strength chain and a lightweight hardened Ergal sprocket — the ideal technical combination for a reliable transmission with a racing look on the road or during powerful rides.
