Rad Valve For A 2018 KTM 250 EXC

MAXIMUM POWER ACHIEVED THROUGH AIR INTAKE, ACCELERATION AND DISTRIBUTION.

Designed for 2018 KTM 250 EXC, this Boyesen component is built to support dependable fitment, durability, and reliable performance for serious riders.

The Boyesen Rad Valve features a sophisticated array of performance attributes designed to provide peak horsepower gains, durability, and model-specific performance for each make/model/year machine. What makes the Boyesen Rad Valve design superior to stock or other aftermarket intake tract reed valve systems? Each Boyesen RAD Valve is unique - tailor made to that model, year and displacement. With the new RC2 Rad Valve System, Boyesen engineers have created 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 in 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. 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. Internal precision surfacing treatment eliminates all hard edges that interrupt with the proper delivery of air and fuel. Attention to the specific air and fuel requirements of each machine's unique engine pressures gives the RC2 Series Rad Valve the ability to reach consistent peak horsepower gains, optimizing the power profile to produce instant, explosive movements of air. The Result: Unparalleled performance.

X-CROSS DUAL CARBON WEAVE

The Rad Valve's Multi-Staged reed petal stacks feature the absolute highest quality aerospace grade carbon material interwoven into specific tension combinations that maximize power delivery and peak horsepower. Boyesen engineers specifically tune the carbon matrix tension using a proprietary weave formula and special layup techniques that optimize each Rad Valve Reed to work in unision with the engine unique intake pressure pulses for each make/model/year machine.

MS PLUS FLOW OPTIMIZATION

Boyesen's race-proven MS PLUS Optimization uses multi-staged reed petals to distribute the engine?s pulse forces over more surface area. By using a multiple reed petal stack, it is possible to acheive peak horsepower and durability. The patented multi-stage design incorporates a specially shaped top reed petal and a ported bottom reed petal. The top petal is lightweight and resilient for crisp throttle response at partial throttle or low RPM. The stiffer, bottom petal is ported to provide maximum flow and horsepower at higher RPM.
