Boyesen RC2 Radvalve Valve boxHONDA 125 CR 125 R (JE01) - 1998 - 1999Ref : 360039 / 1020940

Boyesen engineers have developed a series of technical innovations for their range of intake systems aimed at optimizing power, torque, and flexibility: Aerodynamic Surface Optimization, Model-Specific Reed Petal Tensioning, Material Fuel Resistance, and Multi-Stage Reed Timing.
BOYESEN reed valves are specifically developed for each motorcycle model.

• 100% aluminium valve body, optimised internal surface state
• 4-way diffuser to optimise flows and prevent pressure losses
• Intake pipe and mounting clamps provided, direct fit without modification
• Variable flexibility reeds, specific to each model (Aerospace quality carbon)
• Rubber-coated reeds resistant to hydrocarbons ensuring prolonged seal life

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