Boyesen Power Reed Dualstage Aprilia Rs/Rx125 Extreme/Sport/Replica 72-19 Renthal UFO Complete Body Kit (OEM)One 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.
