The Gulp Factor - 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
"Power Channeled Charge" - Integrated into the seamless inner chamber are 4-way aerodynamic directional dividers that distribute the angled charge evenly without flow loss. Each channel has its own unique Power Profile, scientifically shaped to produce instant, explosive movements of air. Result: Unparalleled performance
"Intelligent" Dual Stage Reed System" - Standard equipment have the superior ability to time themselves to the needs of the engine. You get maximum flow velocity across the entire RPM range, and at all throttle settings. Smooth. Sharp. Smart. Result: Full Spectrum power and throttle response
There's a Rad Valve Engineered to YOUR Make, Year, and Model - Each Boyesen RAD Valve is unique - tailor made to that model, year and displacement. 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. Result: A true, bolt-on Power Boost
Boyesen's Rad Valve features complete intake tract. Maximum power achieved through air intake, acceleration, and distribution. Features four key breakthrough factors make Boyesen RAD Valves the most advanced air intake system you can add to your bike!
