X-CROSS DUAL CARBON WEAVE
All RC2 Pro Series reeds feature the absolute highest quality aerospace grade carbon material interwoven into specific tension combinations that maximize power delivery. Boyesen engineers specifically tune the carbon matrix tension using a proprietary weave formula and special layup techniques that optimize each specific reed tension to work in unision with the engine's 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.part number cross reference
