Clap box BOYESEN Rad Valve carbon lamelles Kawasaki KX65

The Boyesen engineers have developed a series of technical innovations on its range of intake systems to optimize power, torque and flexibility: Aerodynamic Surface Optimization (internal area optimization), Model-Specific Reed Petal Tensioning (especial to each model), Material Fuel Resistance (hydrocarbon-resistant equipment, and Multi-Stage Reed Timing (clap). Clap boxes BOYESEN are developed specifically for each motorcycle model Box body 100% aluminium, optimized internal surface conditionDiffusor 4 lanes to optimize fluxes and avoid load lossesIntake and fastening clamps provided, direct assembly without modificationClaps with variable flexibility, specific to each model (In carbon Aerospacial)Claps made of rubber and resistant to hydrocarbons guaranteeing an extended life of the joints The RC2 clap boxes, developed in competition, significantly optimize the intake streams, which leads to more efficiency, more power and better rides on your bike!
