RK 525 ZXW - Drive Chain - 170 Links - Green MM525ZXW-170

If you're running high displacement engines or extended swingarm setups at the track, chain failure isn't an option—it's a catastrophic loss. The RK 525 ZXW is engineered specifically for these extreme conditions, delivering the durability and heat resistance that separates reliable performance from costly downtime. The advanced XW-Ring seal design keeps your chain lubricated and protected where standard chains simply can't compete.

Built for serious racers and high-horsepower builds, this 170-link chain handles sustained high-speed operation without compromise. The three-contact-lip seal system and dual lubrication pools work together to eliminate wear from dirt ingestion, abrasion, and thermal stress—keeping your drivetrain efficient lap after lap.
