NEW KTM specific, RC2 Series Rad Valves
RC2 Ultra Flow Tech yeilds best in class power, with the most durable reeds available!
For 2013, Boyesen is proud to release our new Rad Valve RC2 Series Reed System for select KTM MX/Offroad models. This new version of the popular 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 RC2 Series Rad Valve design superior to stock or other aftermarket valve systems? It's the only complete intake tract system with aerodynamic internal surfacing. Aero Optimized Internal Surfacing is a precision digital modeling design process applied to the interior of the valve effectively eliminating all hard edges that interrupt the 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 model gives the RC2 Series Rad Valve the ability to reach consistent peak horsepower gains, optimizing power delivery for each specific KTM application. This is not a one-size-fits-all design.

Tired of breaking your stock reeds? Boyesen's RC2 Series Rad Valve now features category-leading toughening additives to increase reed petal lifespan by resisting breakdown from damaging agents found in fuel. In addition to the Rad Valve's proprietary T2 Epoxy, it also features model-specific tensioned reed petals usingBoyesen's advanced X Cross Dual Carbon layup process. The Rad Valve's multi-staged reed petal stacks feature 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 model of machine.

Boyesen's "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 petal is 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. Multi-stage reeds work in unison to perform efficiently throughout the entire powerband. The difference in stiffness between the top petal and the bottom petal 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. The dual-stage design also allows you to replace your stock reed stop with a Rev-Plate which permits the petals to open freely and function efficiently.

Most KTM SX, XC, and EXC models and engine sizes ranging from 1998 - 2013.

The MSRP of the KTM specific RC2 Series Rad Valves range between $169.95 to $179.95 (USD).
