Boyesen Motocross Reeds

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.

Boyesen Dual-Stage Reed Design Features:

• Dual stage reeds
• Minor change gives major H.P. improvements
• Faster opening and closing
• Greater low pressure (Low-throttle) response
• Greater velocity and flow area
• Longer overall life
• No engine damage if broken
• Carbon pro has a new carbon fiber reed for quicker response

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 provide 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.

Boyesen Pro Series Reed Design Features:

• 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, and 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.
