EK/PBR 525ZVX3 Chain Kit 17/45 - Ultra-Light Sprocket
Designed by EK CHAIN for large displacement motorcycles, this 525 ZVX3 kit combines a premium chain and an ultra-light aluminum sprocket to reduce unsprung mass and enhance throttle response. The gold/gold finish provides a sleek and durable look, ideal for sport roadsters and hypersport bikes seeking to blend performance and style.
The ZVX series is developed to offer superior rigidity and longevity, suitable for the demands of powerful engines. Easy installation as an OEM replacement: chain, sprocket, and rear sprocket are sized to maintain the original geometry and facilitate maintenance (regular lubrication and tension checks recommended).
Particularly suitable for sport models like the BMW S 1000 RR (2016–2018) and other high-displacement roadsters. A relevant choice for those wanting a robust, lightweight, and aesthetically pleasing transmission, without compromising on reliability.
