Key item features
- Dual-Stage Design: Boyesen's patented dual-stage design incorporates a specially shaped top reed and a ported bottom reed, allowing for efficient operation across the entire powerband.
- Optimized Response: The lightweight top reed provides crisp throttle response at partial throttle or low RPMs, while the stiffer, ported bottom reed delivers maximum flow and horsepower at higher RPMs.
- Enhanced Airflow: The dual-stage design replaces the stock reed stop with a Rev-Plate, permitting reeds to open freely for increased airflow and improved efficiency.
- Increased Velocity: The multi-port feature of the bottom reed creates more channels for the charge, delivering increased velocity to the intake ports for greater overall power.
- Durable Construction: Manufactured with Boyesen's exclusive DURA *FLEX material, these reeds offer longer overall life and are matched to OEM specifications.
- Performance Benefits: This design translates into quicker acceleration, crisper throttle response, increased horsepower throughout the powerband, and improved engine efficiency.

About this item
Product details
- Offers maximum performance
- Made with Boyesen's patented dual stage fiberglass design for more airflow delivering more usable power than stock reeds
- Manufactured with Boyesen's exclusive DURA *FLEX material
- Your original one stage reed operates most effectively only within a narrow RPM range while 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
- Minor change gives major H.P. improvements
- Top reed opens at lower RPMs allowing for more air and fuel flow giving you better throttle response
- Bottom reed opens at higher RPMs for maximum flow
- Faster opening and closing
- Greater low pressure (low throttle) response
- Greater velocity and flow area
- No engine damage if broken
- Longer overall life
- Matched to O.E.M specs
- More air velocity equals more overall power
Note: Two sets required for part number 304-0645. Image for reference only. Actual product may vary according to vehicle.
- Boyesen's patented dual-stage design incorporates a specially shaped top reed and a ported bottom reed
- The top reed is lightweight and resilient for crisp throttle response at partial throttle or low RPMs. The stiffer, bottom reed is ported to provide maximum flow and horsepower at higher RPMs
- More Air Flow. The dual-stage design allows you to replace your stock reed stop with a Rev-Plate which permits the reeds to open freely and function efficiently
- More Air Velocity. The multi-port feature of the bottom reed creates more channels for the charge, delivering increased velocity to the intake ports
- More Overall Power. Dual-stage reeds work in unison to perform efficiently throughout the entire powerband. The difference in stiffness between the top reed and the bottom reed allow the reeds to respond quickly and accurately to changes in engine pressure. This translates into quicker acceleration, crisper throttle response and increased horsepower throughout the powerband
- The price shown is for one set of reeds. Please check your vehicle whether you need one or two sets of reeds.
- Quicker acceleration for that all-important holeshot
- Crisper throttle response for fast corner exits and surer jumps
- More horsepower throughout the powerband for guaranteed performance
- Improved engine efficiency and fuel economy for the long distance rider
- Longer life - Boyesen Power Reeds outlast all other aftermarket reed petals
- NOTE: Certain models need to use the stock metal stops when installing the new reeds
