Boyesen Factory Racing Rad Valve Yamaha

MAXIMUM POWER ACHIEVED THROUGH AIR INTAKE, ACCELERATION AND DISTRIBUTION

Each Boyesen RAD Valve is unique – tailor-made to that model, year and displacement.
Boyesen engineers embarked on a mission to create a new lineage of aerodynamic intake technology by refining the primary performance factors required to increase peak horsepower through design innovation: Aerodynamic Surface Optimization, Model-Specific Reed Petal Tensioning, Material Fuel Resistance, and Multi-Stage Reed Timing. Together, these innovations create a new technological benchmark for intake performance. The next generation RC2 series Rad Valve results in an optimized air intake system that provides superior efficiency, peak horsepower gains, and acceleration for YOUR specific model machine.

Your engine is a glutton for air. It will take over 200 “gulps” per second, at velocities over 500 MPH – if your intake valve will let it. The Rad Valve’s seamless, one-piece, precision casting and continuous aero form surface ensures maximum flow velocities and instant, explosive movement of air particles the moment you open the throttle.

While other aftermarket valves might change flange sizes or bolt patterns, they’re basically generic – and require you to irreversibly cut your intake boot to install it! But with the RAD Valve, there are no compromises in power, no modifications. The Result: A true, bolt-on Power Boost.
