MOVE UP WITH CARBON AND DUAL-STAGE TECHNOLOGY
Quickest acceleration any reed can
offer for that all important holeshot
Crisper throttle response making
challenging obstacles effortless
More overrev so you can run a gear
longer going into a corner or jump
Increased life over traditional carbon fiber reeds
The most potent reed available delivering
power you can have confidence in
Q: What advantage do Pro Series Reeds
have over Power Reeds?
A: Pro Series dual-stage reeds combine a carbon-fiber top reed with a fiberglass bottom reed for unrivaled performance. The Pro Series Reeds are more responsive than our traditional Power Reeds. The carbon-fiber top reed has excellent response characteristics that provide even quicker acceleration, stronger throttle response, and more over-rev than our standard Power Reeds. The fiberglass bottom reed provides stability and longer reed life. |

REVOLUTIONARY PERFORMANCE
Boyesen's patented dual-stage design incorporates a specially shaped top reed and a ported bottom reed. The top reed is lightweight and resilient for crisp throttle response at partial throttle or low RPMs. The stiffer, bottom reed is ported to provide maximum flow and horsepower at higher RPMs. More valves equals more power by creating:
More Air Flow. The dual-stage design allows you to replace your stock reed stop with a Rev-Plate which permits the reeds to open freely and function efficiently.
More Air Velocity. The multi-port feature of the bottom reed creates more channels for the charge, delivering increased velocity to the intake ports.
More Overall Power. Dual-stage reeds work in unison to perform efficiently throughout the entire powerband. The difference in stiffness between the top reed and the bottom reed allow the reeds to respond quickly and accurately to changes in engine pressure. This translates into quicker acceleration, crisper throttle response and increased horsepower throughout the powerband. |

MAXIMUM POWER ACHIEVED THROUGH AIR INTAKE, ACCELERATION AND DISTRIBUTION
Four key breakthrough factors make Boyesen RAD Valves the most advanced air intake system you can add to your bike!
1. 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. The 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.
2. "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.
3. "Intelligent" Dual-Stage Reed System
Standard equipment on each RAD Valve, Boyesen dual-stage, Pro Series Reeds 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. Smoth. Sharp. Smart.
Result: Full Spectrum power and throttle response.
4. There's a Rad Valve Enginneered To
YOUR Make, Year & 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.
