The Boyesen 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.
- FASTER STARTS: No more sitting and cranking cranking when engine is cold or hot
- SMOOTHER IDLE: No more coughing, sputtering and dying.
- Blazing acceleration for that all-important holeshot.
- More horsepower throughout the powerband for guaranteed performance.
- Smoother Trolling: Troll down to a heartbeat with the controll of Boyesen Power Reeds
- Improved engine efficiency and fuel economy. Up to a 10% increase
- Longer Service life - Boyesen Power Reeds outlast all other aftermarket reeds.

At Boyesen, R&D is hands-on, tested in the field, and tied to feedback from the end user. They use the latest computerized testing and manufacturing processes available in the industry. From research through production, Boyesen is committed to using creative concepts, new materials, and better designs that will increase the satisfaction and enjoyment of their customers.
Eyvind Boyesen, president and founder, started a performance revolution
in 1972 on a shoestring budget and a single patent in hand. He used
reed induction technology, in combination with his patented dual-stage
reed, to produce instantly stunning results. Motorcycles using Boyesen
reeds were consistently outperforming bikes using other modes of intake
induction. On and off the race track circuit, the Boyesen name became
equated with superior performance, quality, and service.
From those first days, applications
for Boyesen technology have expanded to include intake products for
watercraft, snowmobiles, and outboard marine engines. Manufacturing has
been and continues to be perfected with painstaking precision and care,
insuring the highest quality standards for the ultimate in trouble free
performance. Through licensing agreements, technology designed and
patented by Boyesen is built into two-stroke engines around the world.
More than two decades and many patents later, motorcycle racers and
motorsport enthusiasts around the world have turned Boyesen Engineering
into a company serving people on six continents.
Because of his dual-stage reed
innovation, Eyvind Boyesen became known as the "Reed Man" throughout
the industry. Never content with "good enough," this Norwegian born
inventor has been obsessed with the desire for continual improvement.
Man made inventions, such as the internal combustion engine, could
never be said to "have arrived" at perfection. The reason is that human
inventiveness is never static but is always capable of achieving new
insights and a better understanding of the dynamic forces of energy and
matter. This explains the motivating principle behind the company: to
bring creative engineering solutions into the marketplace. But Eyvind
Boyesen is not finished yet. There are a number of plans on his drawing
board; prototyped, tested, and ready for the right moment to enter the
Boyesen Engineering is presently committed to the ongoing development of:
- Innovative performance products for the Powersports Industry
- Reed induction systems for two-stroke engines
- Consulting and research services related to two-stroke engine design.
- The development of technologies and new product lines that will
enhance performance in the small engine and recreational marketplace
