Are you a weekend warrior looking for the highest performing parts for your bike? Then Boyesen is the name you can trust. The company specializes in advanced air intake parts for two-stroke engines. Boyesen’s strong focus on R&D allows it to raise the bar for performance and quality. It strives to use unique concepts and designs that will surely take your riding enjoyment to the next step. Boyesen reed valves are proven to enhance airflow and air velocity, resulting in better fuel economy and added power. Boyesen RAD valves will enable sharper throttle response, increase peak horsepower, and add torque for improved cornering. 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.

While Boyesen is recognized worldwide for its top-notch intakes, the company also offers water pump covers, power wings, ignition covers, clutch covers and other related parts that are guaranteed to make your engine look and perform at its peak. Boyesen power wings increase airspeed at all throttle settings, significantly maximizing the efficiency of your carbureted intake system. SuperCooler water pump cover and impeller kits are the perfect way to keep your cooling system running at its maximum. They are specifically designed to increase pump capacity, allowing for better coolant flow at any RPM. Boyesen clutch and ignition covers will add a touch of style to your bike, setting it apart from the rest.
