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 valves equals more power by creating:
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.
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
Reeds are sold per valve
Made in the USA

Questions & Answers
Do the petals bolt onto the stock valve intake?
By Mechanix
I have a 99 kawasaki kx80 and i want to pick up a set but wondering do they bolt right onto the oem equipment?
Yes, these particular reeds will fit the OEM valve without any other modifications. Just remove the old reeds, put these on and you're all set!
These fit stock Reed cages
By Robby S.
2000 ktm 125
Yes, that's correct. Boyesen Power Reeds are designed to fit the OEM reed cage on any machine you select from our fit guide, including the 2000 KTM 125's stock reed cage.
So would I need to order 2 of these to replace the reeds on my intake for a 98 kx60
By Justin
As is noted in the item's description, Boyesen Power Reeds are sold per-valve. You'd only need to purchase a quantity of one to service the OEM reed cage on your KX60.
