Description
The stock reed valve is one of the most overlooked performance bottlenecks in two-stroke engines. Boyesen’s dual-stage reed design unlocks measurable flow improvements across the entire RPM range, translating to sharper throttle response and more usable power from idle to redline. If you’re serious about extracting every bit of performance from your KX125, this is non-negotiable.
Engineered through rigorous laboratory flow analysis, these reeds permit greater flow velocity at all operating pressures—meaning your engine breathes easier when it matters most. The result is noticeably quicker acceleration and more consistent performance characteristics throughout your power band.
