APPLICATIONS: KTM85SX : 2009-2016, HUSQVARNA TC85 : 2014-2016

Boyesen Engineering would like to introduce the all-new RC2 Series Rad Valve, designed to increase overall horsepower and throttle response in the 2009-2016 KTM 85 SX and the 2014-2016 Husqvarna TC 85.

The new RC2 Series Rad Valve is “Performance Optimized” - tailor made to give the new KTM85 and Husky 85 greater roll on response and horsepower. The RC2 Series Rad Valve, there are no compromises in reed life, and no modifications required to fit the valve while upgrading your minis reed system. The Result: A true, bolt-on Power increase specifically made for YOUR KTM and Husky.

The RC2 Series Rad Valve multi-stage reed petal system has been designed to increase throttle response and acceleration, while also broadening peak RPM horsepower output. The Rad Valve’s 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 Boyesen’s dual-stage carbon reed petals. The race-proven reed petals are integral in providing the superior ability to maintain timing with the power pulses of the Yamaha engine platform. 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 Valve’s 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 engine's platform.

Model-specific reed tension for maximal response.
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 model-specific, carbon weave formula that is tested and optimized.

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 engine’s 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 Boyesen RC2 Series Rad Valve system is available at your local dealer or popular web retailers. If your regional dealership has chosen not to stock this product, Boyesen also makes it available for purchase at our webstore. Visit for more information, or to make your purchase.
