Description
Reed valve performance directly impacts throttle response, acceleration, and peak horsepower on 2-stroke engines—and the Boyesen Pro Series delivers measurable gains across all three. This dual-stage design responds instantly to piston speed changes, eliminating the sluggish response common with inferior reeds while maintaining the durability needed for serious competition. If you’re serious about CR250 performance, upgrading to carbon fiber reeds is one of the highest-return modifications available.
