Boyesen Motorcycle valve box Rad Gasgas

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

• 100% aluminium body, optimized internal surface state
• 4-way diffuser to optimize flows and prevent pressure losses
• Intake pipe and mounting clamps included, direct installation without modification
• Variable flexibility reeds, specific to each model (Aerospace quality carbon)
• Rubber-coated reeds resistant to hydrocarbons ensuring a longer lifespan of the gaskets

The RC2 reed boxes, developed for competition, significantly optimize intake flows, leading to greater efficiency, more power, and better throttle response on YOUR motorcycle!
