Boyesen RC2 Radvalve Valve boxRef : 360004 / 1020977

Boyesen engineers have developed a series of technical innovations for their range of intake systems aimed at optimizing power, torque, and flexibility: Aerodynamic Surface Optimization (internal surface optimization), Model-Specific Reed Petal Tensioning (model-specific reed petals), Material Fuel Resistance (hydrocarbon-resistant materials), and Multi-Stage Reed Timing (staged opening reeds).
The BOYESEN reed valves are specifically developed for each motorcycle model.

• 100% aluminium valve body, optimised internal surface condition
• 4-way diffuser to optimise flow and prevent pressure losses
• Intake pipe and mounting clamps included, direct fit without modification
• Variable flexibility reeds, specific to each model (Aerospace quality carbon)
• Rubber-coated reeds resistant to hydrocarbons ensuring prolonged seal life

RC2 reed valves, developed in competition, significantly optimise intake flow, resulting in greater efficiency, more power, and better revs on YOUR motorcycle!
