Boyesen RL-03 Dual-Stage Power Reed Valve System

The Boyesen RL-03 Rad Valve is a revolutionary dual-stage reed valve system engineered to deliver significantly more usable power across the entire RPM range compared to stock single-stage reeds. Unlike conventional reeds that operate effectively only within a narrow powerband, this innovative design features one soft reed layered on top of one firm flow-through reed, providing superior intake control and increased intake velocity that stock reeds simply cannot match.

Key Features:

• Dual-stage reed design with variable stiffness for optimal response throughout the powerband
• Soft top reed paired with firm bottom flow-through reed for wide-range intake control
• Includes Rev-Plate reed stop replacement that allows reeds to open freely and function efficiently
• Multi-port bottom reed creates additional channels for improved charge velocity
• Reeds work in unison to respond quickly and accurately to changes in engine pressure
• Direct replacement for stock reed valve assemblies

The multi-port feature of the bottom reed creates more pathways for the air-fuel mixture, delivering increased velocity to the intake ports and generating more overall power. The difference in stiffness between the two reeds enables them to respond rapidly to fluctuations in engine pressure, translating into quicker acceleration, crisper throttle response, and increased horsepower throughout the entire powerband. This proven design gives you the competitive edge whether you're racing or riding recreationally.
