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.</p><ul><li>Dual stage reeds</li><li>Minor change gives major H.P. improvements</li><li>Faster opening and closing</li><li>Greater low pressure (Low-throttle) response</li><li>Greater velocity and flow area</li><li>Longer overall life</li><li>No engine damage if broken</li><li>Carbon pro has new carbon fiber reed for quicker response</li></ul><p><strong>PRO SERIES IS THE ULTIMATE PERFORMANCE PRODUCT</strong><br>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.</p><p><strong>What advantage do Pro Series Reeds have over Power Reeds?</strong><br>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.</p><p><strong>XCROSS DUAL CARBON WEAVE<br>Model-Specific variable tension reed petals.</strong><br>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.</p><p><strong>T2 EPOXY<br>The most durable materials. The most lifespan. </strong><br>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.</p><p><strong>MS PLUS FLOW OPTIMIZATION<br>One reed petal is NOT enough!</strong><br>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.</p><p> </p><p><strong>PROP 65 WARNING:</strong> Cancer and/or reproductive harm - <a href='https://www.P65Warnings.ca.gov' rel='noopener' target='_blank'>www.P65Warnings.ca.gov</a></p>",

"description": "<p>Boyesen’s revolutionary dual-stage reed design delivers more<br>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.</p><ul><li>Dual stage reeds</li><li>Minor change gives major H.P. improvements</li><li>Faster opening and closing</li><li>Greater low pressure (Low-throttle) response</li><li>Greater velocity and flow area</li><li>Longer overall life</li><li>No engine damage if broken</li><li>Carbon pro has new carbon fiber reed for quicker response</li></ul><p><strong>PRO SERIES IS THE ULTIMATE PERFORMANCE PRODUCT</strong><br>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.</p><p><strong>What advantage do Pro Series Reeds have over Power Reeds?</strong><br>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.</p><p><strong>XCROSS DUAL CARBON WEAVE<br>Model-Specific variable tension reed petals.</strong><br>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.</p><p><strong>T2 EPOXY<br>The most durable materials. The most lifespan. </strong><br>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.</p><p><strong>MS PLUS FLOW OPTIMIZATION<br>One reed petal is NOT enough!</strong><br>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.</p><p> </p><p><strong>PROP 65 WARNING:</strong> Cancer and/or reproductive harm - <a href='https://www.P65Warnings.ca.gov' rel='noopener' target='_blank'>www.P65Warnings.ca.gov</a></p>",
