Product Details

The Boyesen RAD-04A Reed Valve System represents a sophisticated upgrade for performance-oriented 2-stroke engines, delivering measurable horsepower gains through advanced intake tract technology. Unlike generic aftermarket reed valves, each Boyesen RAD Valve is engineered with model-specific performance characteristics tailored to optimize airflow and power delivery.

Key Performance Features:

  • Aerodynamic Surface Optimization: Refined intake tract geometry maximizes airflow efficiency and reduces turbulence
  • Model-Specific Reed Petal Tensioning: Custom-tuned reed stiffness provides optimal response across the powerband
  • Advanced Material Construction: Fuel-resistant materials ensure long-term durability and consistent performance
  • Multi-Stage Reed Timing: Progressive reed opening characteristics improve throttle response and acceleration
  • True Bolt-On Installation: Direct OEM replacement design requires no cutting or permanent modifications to intake boots

The RAD Valve system maintains factory flange sizes and bolt patterns, ensuring a straightforward installation that preserves the integrity of your machine's intake system. This design philosophy delivers peak horsepower improvements and enhanced throttle response without compromising reliability or requiring irreversible modifications.

I love to shop at Autoplicity because of their selections and pricing options. Fast shipping and great customer service. The only thing I'd like to see is the site needs a continue shopping option after looking at cart. My overall experience has always been a 5-Star rating.
