Boyesen Carbon Tech Reeds
Don't settle for anything less than the best. Boyesen Carbon Tech reeds are made from aerospace-grade, 100 percent carbon fiber--meaning they're long lasting and give better performance. They bolt directly to your stock reed cage without modifying anything else on your intake system and are available in different reed petal tensions to suit the track and your riding style. Reed petal tensions: * Low Tensions (LT) improve power delivery in the lower rpm ranges and are best suited for increasing response and initial acceleration * Mid Tensions (MT) improve power delivery in the mid-range and are ideal for increasing the overall power delivery of your engine * High Tensions (HT) improve power delivery in the upper rpm range and increase maximum output.
