Boyesen's patented dual-stage reed valve design delivers maximum throttle response, acceleration, and horsepower across the entire RPM range. By combining a specially shaped top reed with a ported bottom reed, the system optimizes airflow dynamics at both low and high engine speeds.

The top reed is lightweight and responsive for crisp throttle control at low RPMs, while the bottom reed is stiffer and ported for high airflow at peak RPMs. This dual-action design delivers superior performance compared to single-stage reeds.

Performance Advantages:

• Quicker acceleration – Ideal for fast holeshots and quick power delivery off the line
• Crisper throttle response – Smoother transitions and quicker recovery out of corners and over jumps
• More horsepower – Increased airflow and efficient reed operation at all RPMs
• Improved engine efficiency – Enhanced fuel economy for extended rides and endurance racing
• Longer-lasting reeds – Outlast other aftermarket petals, reducing maintenance and replacement costs

How It Works:

• More Air Velocity – Multi-port bottom reed increases charge velocity to intake ports
• Dual-Stage Efficiency – Lightweight top reed and stiffer bottom reed work in sync to respond to changing engine pressure
• Full Powerband Coverage – Delivers consistent performance from idle to redline

Whether you're a weekend trail rider, motocross racer, or high-performance builder, Boyesen Power Reeds offer a proven performance upgrade that improves power delivery, responsiveness, and durability.
