Pro Circuit Clutch Springs for Kawasaki (CSK09085)

Upgrade clutch performance with Pro Circuit CSK09085 Clutch Springs, engineered for Kawasaki applications. These performance springs are designed to provide a firmer clutch feel and more positive engagement than stock springs, helping riders manage power delivery with greater control. Built for demanding riding conditions, they support consistent performance during acceleration, shifting, and repeated clutch use.

With spring rates approximately 12–15% stiffer than stock, the Pro Circuit CSK09085 springs help reduce clutch slipping and improve the connection between engine output and rear-wheel acceleration. The increased stiffness can provide more controlled engagement, allowing the clutch to transfer power efficiently while maintaining predictable operation. This makes them a practical upgrade for riders seeking improved response without sacrificing clutch feel.

Each spring is manufactured to deliver consistent performance throughout its service life. Pro Circuit’s clutch spring design helps control how efficiently the clutch turns engine power into acceleration, making the CSK09085 a suitable choice for performance-focused Kawasaki motorcycles and off-road applications. Verify motorcycle fitment before installation and follow the manufacturer’s service procedures for proper clutch adjustment.
