Boyesen RAD Valve high performance intake system for 2 strokes.

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 aeroform surfaces ensure 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.

AERO OPTIMIZED INTERNAL SURFACING
The Rad Valve is the ONLY air intake system available with aerodynamic internal surfacing.

Integrated into the Rad Valve's seamless interior 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. The Result: Unparalleled performance.

Internal precision surfacing treatment eliminates all hard edges that interrupt with the proper delivery of air and fuel. Because internal air turbulence is virtually non-existent, the proper air/fuel control is optimized for each make/model/year machine. This attention to the specific air and fuel requirements of each machine's engine gives the RC2 Series Rad Valve the ability to reach consistent peak horsepower gains, optimizing power delivery for each specific application.

XCROSS DUAL CARBON WEAVE
Model-Specific variable tension reed petals.
The Rad Valve's Multi-Staged reed petal stacks feature Aerospace carbon material interwoven into tension combinations that maximize power delivery and peak horsepower. Boyesen engineers specifically tune the carbon matrix tension using a proprietary weave formula that is tested and optimized for each make/model/year machine.
