EK/JT 525ZVX3 Chain Kit 16/42 - Standard Sprocket
The ZVX series from EK CHAIN represents the premium high-strength range dedicated to motorcycle transmissions. This 525ZVX3 kit, designed for high-displacement and demanding roadsters, includes a 525 chain and a standard 42-tooth sprocket matched with a 16-tooth pinion, ready to replace your entire final drive system.
Designed to offer rigidity and longevity, the ZVX is suitable for the mechanical demands of heavy roadsters and sportbikes. The kit is particularly aimed at owners of the Honda CBR 900 RR FIREBLADE (SC33) 1997‑1999 (900 cc), but is compatible with any motorcycle requiring a 525 setup in 16/42. To get the best performance from the chain, regularly check the tension, lubricate according to manufacturer recommendations, and replace both the chain and sprockets for even wear.
