For: Fantic 249 all models; Fantic 309 all models; Honda CR80 1987-2002; Honda CR80 Expert 1996-2002; Honda CR85 and CR85 Expert 2003-2008; Suzuki RM80 1989-2001. Power reeds use a patented dual stage fiberglass design for more air flow, more air velocity and more power. 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. Longer overall life: Boyesen power reeds outlast all other aftermarket reed petals. Minor change gives major horsepower improvements and fuel economy. Fit type: Vehicle Specific
