BOYESEN Single-Stage Reed - Fiber - YZ125 '01 SSF231

Reed valves are critical to two-stroke engine performance, directly controlling intake timing and fuel charge efficiency. The Boyesen SSF231 single-stage fiber reeds deliver consistent performance across the entire RPM band while maintaining OEM-spec compatibility with your YZ125. If you're running stock reeds, upgrading to these will noticeably improve throttle response and overall engine responsiveness.

These reeds are engineered as complete cylinder sets, meaning one set per cylinder gives you optimized performance without compromise. The fiber construction offers superior durability compared to stock options, reducing replacement frequency while providing better value than premium carbon alternatives. Installation is straightforward—bolt-on replacement with no fabrication required.
