Boyesen Rad Reed Valve - Honda CR125R

The engineers at Boyesen have developed a series of technical innovations in their intake systems to optimize 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 designed for each motorcycle model.

• 100% aluminum valve body with optimized internal surface finish
• 4-way diffuser to optimize flow and prevent pressure drops
• Intake pipe and mounting clamps included, direct installation without modification
• Model-specific variable flex reeds (made of Aerospace quality carbon fiber)
• Reeds coated with rubber and resistant to fuel for extended seal life

The RC2 reed valves, developed in competition, significantly improve intake flow, resulting in increased efficiency, more power, and better throttle response on YOUR bike!
