Description
Reed valve performance directly impacts your engine’s throttle response and peak horsepower output. The Boyesen Pro Series PSR-209 uses a patented dual-stage design to maintain consistent reed action across the entire RPM range, eliminating the hesitation and inefficiency of traditional single-stage reeds. With a carbon fiber top reed paired to a reinforced fiberglass/epoxy bottom reed, you get maximum acceleration and torque without the accelerated wear that plagues conventional carbon fiber alternatives.
