About this item

  • Fits: Honda CR125 1992-1997
  • The RAD valve's seamless, one-piece, precision casting and continuous aero form surfaces ensure maximum flow velocities and instant, explosive movement of air particles the moment you turn the throttle
  • Integrated into the seamless interior chamber are 4-way aerodynamic directional dividers that distribute the angled charge evenly without flow loss
  • Optimized air intake system provides superior efficiency, peak horsepower gains, and acceleration for YOUR specific model machine, tailor made to that model, year and displacement
  • Increases peak horsepower through Boyesens own innovations: Aerodynamic Surface Optimization, Model-Specific Reed Petal Tensioning, Material Fuel Resistance, and Multi-Stage Reed Timing

I am very happy with the improvement in power. Very impressive. One detail : bolts must be changed to avoid interference (use smaller head, 8 instead of 10).
