IMPROVED INTAKE RESPONSE

Designed for 2000 gas gas EC 250, these Boyesen reeds are engineered to improve airflow efficiency, throttle control, and power delivery. Built with performance-focused materials, they help your engine respond more cleanly across demanding riding conditions.

T2 EPOXY

The RC2 Pro Series reeds now feature category-leading toughening additives to increase reed petal lifespan by resisting breakdown from damaging agents found in fuel. All RC2 Series Carbon Tech Reeds contain a proprietary formulation of resin additive that works to create stronger molecular alignment while maintaining the carbon's overall modulus of elasticity.

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.
