The RK 525 ZXW drive chain is designed for high-speed, high-horsepower motorcycle applications, including large-displacement motorcycles and machines equipped with extended swingarms. This 525-size chain features 120 links and a black scale finish, providing a durable replacement or upgrade for demanding drivetrain requirements.
RK manufactures the ZXW series with an XW-Ring seal that uses three contact lips and two lubrication pools at each seal point. This design helps protect the chain’s internal lubricant from dirt and debris while supporting reliable performance during high-speed operation. It also helps reduce the effects of abrasion, heat buildup, and lubricant loss under extreme riding conditions.
Use the RK BL525ZXW-120 when fitment calls for a 525 chain with 120 links. Confirm the motorcycle’s chain size, required link count, sprocket compatibility, and manufacturer fitment recommendations before installation. The chain is intended for performance-oriented street, sport, touring, and other high-output motorcycle applications where durability and consistent power transfer are important.
