Description
The stock reed valve is your RM85’s biggest restriction to peak performance. Boyesen’s dual-stage reed design has been laboratory-validated to deliver superior flow velocity across the entire operating pressure range, translating to faster throttle response and harder acceleration from low RPM through the top end. If you’re serious about competitive lap times or trail performance, upgrading from OEM reeds is one of the highest-impact modifications available.
