Boyesen PSR-211 Super Stock Fiber Reeds 3-Stage Design

The Boyesen PSR-211 Super Stock Fiber Reeds feature an innovative 3-stage reed design engineered to optimize performance across the entire RPM range. These replacement reeds are designed for Boyesen Rad Valve systems and deliver significant improvements in throttle response, mid-range power, and high-RPM stability.

3-Stage Reed Design:

• Low Tension Top Reeds: Ensure instant throttle response and crisp acceleration from a stop
• Intermediate Reeds: Increase mid-range responsiveness and pull for improved power delivery
• High Tension Base Reed: Provides reed stability for improved high-RPM operation and top-end performance

Important Fitment Note: When ordering replacement reeds for Boyesen Rad Valves, identify your valve type first. Rad Valves with part numbers stamped on the side require Pro Series replacement reeds, while Rad Valves without stamped part numbers require Unstamped Valve replacement reeds. Verify your valve type before ordering to ensure proper fitment.

These Super Stock Fiber Reeds are engineered from durable composite materials designed to withstand the demands of motocross, off-road, and high-performance riding while maintaining consistent performance over time.
