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 optimizing power, torque, and flexibility: Aerodynamic Surface Optimization (optimisation of internal surfaces), Model-Specific Reed Petal Tensioning (model-specific reed petals), Material Fuel Resistance (fuel-resistant materials), and Multi-Stage Reed Timing (staged reed opening).
The reed valves BOYESEN are specially developed for each motorcycle model.

• 100% aluminium reed valve body with optimized internal surface
• 4-way diffuser to optimize flow and prevent pressure loss
• Intake pipe and mounting clamps included, direct fitting without modification
• Variable flexibility reeds, specific to each model (Aerospace quality carbon)
• Reeds coated with rubber and resistant to hydrocarbons ensuring prolonged seal life

The RC2 reed valves, developed in competition, significantly optimize intake flows, leading to more efficiency, increased power, and better revs on YOUR motorcycle!
