Boyesen RC2 Series Rad Valve for 2017-2019 KTM and Husqvarna 250/300 Models
Model Specific Designs Optimize the KTM and Husqvarna Intake. The Best Power, All the Time!
Boyesen Engineering would like to introduce the all-new KTM and Husqvarna RC2 Series Rad Valve, designed to increase overall horsepower and throttle response in the new generation 2017 thru 2019 carbureted engine platform.

The new RC2 Series Rad Valve is Performance Optimized - tailor made to give the new 2017-2019 KTM and Husky 250cc/300cc engines improved roll-on transition from low to mid, and greatly enhanced mid-range torque. The performance goal for the new KTM and Husky engine platform further enhances the smooth and powerful engine performance delivery characteristics that are inherent in the new KTM and Husky engines. The RC2 Series Rad Valve multi-stage reed petal system has also been painstakingly developed and tested to increase throttle response and acceleration, while also broadening peak RPM horsepower output.

The Rad Valves seamless, one-piece, precision casting and continuous aero-form surfacing provide maximum flow velocities and instant, explosive movement of air particles the moment you turn the throttle. Standard equipment on each Rad Valve, are Boyesens dual-stage model-tensioned carbon reed petals. The race-proven reed petals are integral to the Rad Valves ability to maintain timing with the power pulses of the KTM and Husky engine platforms. Your machine will gain maximum flow velocity across the entire RPM range, and at all throttle settings. Smooth. Sharp. Smart.

The ONLY performance system with aerodynamic internal surfacing.
The Rad Valves internal precision surfacing treatment eliminates all hard edges that interrupt the proper delivery of air and fuel. Because internal air turbulence is virtually non-existent, the proper air/fuel control is optimized for the characteristics of the KTM and Husky engine platform.

Model-specific reed tension for maximal response.
The Rad Valves 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 model-specific, carbon weave formula that is tested and optimized for each KTM and Husky model.

One reed petal is NOT enough!
The reed petals in modern 2 stroke engines take an incredible amount of abuse! At peak RPM reed petals are opening and closing hundreds of times per second. Over time, a single reed loses its ability to regulate flow rates in proper proportions. This causes a loss of reed petal reaction and reduces the consistency of peak horsepower. MS PLUS Optimization uses multi staged reed petals to distribute the engines pulse forces over more surface area. By using a multiple reed petal stack, it is possible to achieve peak horsepower AND durability. The patented multi-stage design incorporates a specially shaped top reed petal and a ported bottom reed petal. The top petals are lightweight and resilient for crisp throttle response at partial throttle or low RPMs. The stiffer, bottom petal is ported to provide maximum flow and horsepower at higher RPMs. The result: Full Spectrum horsepower and lightning –fast response.

The most durable materials. The most lifespan.
The RC2 Series Rad Valve now features category leading toughening additives to increase reed petal lifespan by resisting breakdown from damaging agents found in fuel. This is done to ensure a long lasting seal between the petals and the intake tract time and time again, which results in more consistent horsepower for longer periods of time between general intake reed maintenance.

The manufacturers suggested retail price of Boyesens KTM and Husqvarna RC2 Series Rad Valve Intake System is $179.95 (USD).
