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 marketplace. 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
