Boyesen Power Reed Dualstage Yamaha Dt125 88-93, Dt200R 89, 91, & 96 Engine Ice · KTM 85SX 2003One 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.
