Plus, the company rigorously tests its products using state-of-the-art manufacturing equipment to ensure they will last for as long as possible.

The history of Boyesen goes back to 1972 when the company’s founder, Eyvind Boyesen, managed to revolutionize the industry having one patent and a limited amount of money. He produced reeds that outperformed the competition in every possible way. Soon Boyesen became synonymous with exceptional performance and reliability. Several decades later, the company grew into a leader in power reeds serving racers and motorsports enthusiasts on all six continents. Eyvind Boyesen became considered the "Reed Man". Now Boyesen is so trusted that such major manufacturers as Kawasaki and Yamaha integrate the Boyesen technology into their motorcycles. Top level racers such as John Dowd, Chad Reed, Bob Hannah, and many others also rely on Boyesen technology as a part of their winning strategy.
