Description
Stock reeds degrade with use, restricting airflow and robbing your KX500 of consistent power delivery across the RPM band. The Boyesen Single-Stage Reed delivers reliable performance with durable fiber construction that outlasts standard OEM reeds while maintaining cost-effectiveness. Replace your cylinder set with confidence—one set per cylinder ensures optimal scavenging and throttle response whether you’re running stock or modified jetting.
