Boyesen Motorcycle valve box Rad KTM/Husqvarna

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

• 100% aluminium reed box body, optimised internal surface quality
• 4-way diffuser to optimise flows and avoid pressure losses
• Intake pipe and fixing clamps included, direct mounting without modification
• Variable flexibility reeds, model-specific (Aerospace-grade carbon)
• Rubber-coated reeds resistant to hydrocarbons ensuring prolonged seal life

The RC2 reed boxes, developed for competition, significantly optimise intake flows, resulting in greater efficiency, more power, and better revving on YOUR motorcycle!
