Description
A reed valve’s responsiveness directly impacts your engine’s throttle delivery and peak performance—and the BOYESEN Pro Series PSR-205 is engineered to maximize both. By combining carbon fiber’s lightweight strength with a proven dual-stage design, this reed delivers the acceleration advantage you need in competition or high-demand riding. The hybrid construction eliminates the durability sacrifice traditionally associated with full carbon fiber reeds, giving you sustained performance lap after lap.
