XCROSS DUAL CARBON WEAVE
Model-Specific variable tension reed petals.
Boyesen Pro Series Reed's Multi-Staged reed 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.
MS PLUS FLOW OPTIMIZATION
One reed petal is NOT enough!
The reed petals in modern 2 stroke Offroad 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 revolutionary dual-stage reed
design delivers more usable power than stock.
Your original one-stage reed operates most
effectively only within a narrow RPM range.
Boyesen’s one soft reed on top of one firm
flow-through reed gives you a wide range of
intake control, plus increased intake velocity.
Your original reeds can’t possibly duplicate
that performance.
PRO SERIES IS THE ULTIMATE PERFORMANCE PRODUCT
Boyesen Pro Series reeds use a carbon fiber top reed coupled with a
durable fiberglass/epoxy bottom reed. Pro Series reeds offer a quick
and accurate reaction to piston speed for smooth dependable throttle
response.
What advantage do Pro Series Reeds have over Power Reeds?
Boyesen Pro Series dual-stage reeds combine a carbon-fiber top reed
with a fiberglass bottom reed for unrivaled performance. The Pro Series
Reeds are more responsive than our traditional Power Reeds. The
carbon-fiber top reed has excellent response characteristics that provides
even quicker acceleration, stronger throttle response, and more over-rev
than our standard Power Reeds. The fiberglass bottom reed provides
stability and longer reed life.
