Boyesen Motorcycle valve box Rad KTM/Husqvarna

The engineers Boyesen have developed a series of technical innovations in their range of intake systems to optimise power, torque, and responsiveness: Aerodynamic Surface Optimization (optimisation of internal surfaces), Model-Specific Reed Petal Tensioning (model-specific reeds), Material Fuel Resistance (hydrocarbon-resistant materials), and Multi-Stage Reed Timing (staged opening reeds).
The reed valves BOYESEN are specifically developed for each motorbike model.

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

The RC2 reed valves, developed for competition, significantly optimise intake flow, leading to increased efficiency, more power, and better revs on YOUR motorbike!
