Unleash Next-Level Power with the Boyesen Rad Valve
Ditch your stock reed cage and manifold—upgrade to the Boyesen Rad Valve for a bolt-on performance boost you can feel instantly. No cutting, adapting, or re-using old parts—just maximum efficiency, horsepower, and throttle response engineered for your exact make and model.

Key Features:

  • AERO-Optimized Internal Surfacing – Precision surfacing treatment eliminates airflow disruptions, delivering a cleaner, more efficient fuel/air charge straight into the engine.

  • X-Cross Dual Carbon Weave – Boyesen’s proprietary carbon matrix tuning and layup process perfectly syncs each reed with your engine’s unique intake pressure pulses for sharper response and stronger power delivery.

  • MS Plus Flow Optimization – Multi-staged reed petals spread intake pulse forces across more surface area, extending reed life while unlocking maximum performance.

The Boyesen Rad Valve isn’t just a replacement—it’s a purpose-built performance upgrade designed to help your machine breathe, rev, and accelerate like never before. 

*Some models may come with additional RB1 Manifold.
