Description

I pacchi lamellari Boyesen sono composti da un corpo unico in alluminio, lavorato con macchinari CNC di ultima generazione.

La struttura monoblocco consente una compattezza e una precisione di flussaggio unica nel suo genere.

Il corpo in alluminio inoltre mantiene fresca la miscela in ingresso.

Queste caratteristiche, unitamente alle lamelle ottimizzate specificatamente per ogni motore, garantiscono miglioramenti su tutta la curva di erogazione e una risposta al gas fulminea.

I pacchi lamellari vengono forniti completi di tutto il necessario per l'installazione.

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.

T2 EPOXY
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. In addition to our proprietary T2 Epoxy, the Rad Valve now features rubber coated reed petals to ensure a long-lasting seal between the petals and the intake tract time and time again.

MS PLUS FLOW OPTIMIZATION
One reed petal is NOT enough!
The reed petals in modern 2 stroke motocross 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.

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 RPMs. The stiffer, bottom petal is ported to provide maximum flow and horsepower at higher RPMs.
