Improve throttle response and engine performance with Boyesen 690 Dual-Stage Motorcycle Reeds. Designed as a direct-fit reed replacement for select Honda CR125R applications, these performance reeds help optimize intake airflow while providing reliable operation for motocross and off-road riding.
The dual-stage design uses reed petals that open and close quickly, helping deliver stronger low-pressure response at low throttle and improved airflow through the intake system. This can support more immediate acceleration, greater intake velocity, and increased flow area compared with standard reed configurations. The Boyesen 690 is engineered to provide a practical performance upgrade without requiring extensive engine modifications.
These reeds are designed for fitment on 1999 and 2000 Honda CR125R motorcycles. The Boyesen brand is recognized for performance-focused powersports components, and manufacturer part number 690 is built for dependable service and extended overall life. The reed design is also intended to help prevent engine damage in the event of breakage, adding confidence during demanding riding conditions. Verify motorcycle year, model, and existing intake components before installation.
