Boyesen Power Reed Dualstage Suzuki Rm250-400 79-80, Pe250-400 80-81 40079 Moto RFX Pro FAST Wheel SpacersOne reed petal is NOT enough! Boyesen's revolutionary dual stage reed design delivers more usable power than stock. Stock single stage reeds operate most effectively within a relatively narrow RPM range and are limited because of the single stage design. Boyesen's one soft reed on top of one firm flow through reed gives you a wide range of intake control, plus increased intake velocity. Your original reeds can't possibly duplicate that performance.
