XCROSS DUAL CARBONWEAVE
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.
