Boyesen 686 Power Reed Dual Stage Fiberglass for KTM 2-Stroke Dirt Bikes

The Boyesen 686 Power Reed uses a patented dual-stage fiberglass design that delivers more airflow, increased air velocity, and greater overall power compared to stock reeds. Manufactured with Boyesen's exclusive DURA-FLEX material, these high-performance replacement reeds are engineered to maximize the potential of your KTM 2-stroke engine.

Dual-Stage Technology:

• Lightweight, resilient top reed provides crisp throttle response at partial throttle and low RPMs
• Stiffer, ported bottom reed delivers maximum flow and horsepower at higher RPMs
• Dual-stage reeds work in unison to perform efficiently throughout the entire powerband, responding quickly and accurately to changes in engine pressure

Performance Benefits:

• Quicker acceleration and improved holeshot performance
• Crisper throttle response for fast corner exits
• Increased horsepower throughout the entire powerband
• Enhanced engine efficiency and improved fuel economy
• Superior durability - outlasts standard aftermarket reeds

Laboratory flow analysis proves these dual-stage reeds permit greater flow velocity over the entire range of operating pressures, delivering performance gains from start-up to top acceleration. Sold as a complete set for one cylinder.
