Key item features
- 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
