Description
The reed valve is one of the most critical components in your KTM two-stroke engine, directly controlling intake flow and fuel charge efficiency. A stock reed will limit your engine’s breathing potential, restricting power throughout the RPM range. Boyesen’s dual-stage reed design has been proven through laboratory flow analysis to deliver superior performance, allowing greater flow velocity across all operating pressures—translating to noticeable gains from cold start through peak acceleration.
This is a bolt-on upgrade that requires no modifications to your intake manifold, making it one of the highest-return performance modifications available for your 125/200cc machine.
