The Gulp Factor - Your engine is a glutton for air. It will take over 200 'gulps per second, at velocities over 500 MPG - if your intake valve will let it. Boyesen's RAD Valve's seamless, one-piece, precision casting and continuous aeroform surfaces ensure maximum flow velocities and instant, explosive movement of air particles the moment you turn the throttle. 

Result: An intake valve the size of your fist delivers air with the power of a tornado.


We recommend all motorcycle parts are fitted and tested by qualified professionals.
