Description
Your intake system is only as efficient as its reed valve design, and standard reeds leave significant performance on the table across your entire power band. Boyesen’s dual-stage reed design has been proven through laboratory flow analysis to deliver superior flow velocity at all operating pressures, translating to quicker throttle response at low RPMs and sustained power delivery all the way to redline. For Honda and Yamaha applications, this is the measurable upgrade that separates competitive performers from the rest.
