Boyesen Power Reed Trial Sherco 2T St250/290/300 10-15, Scorpa Twenty 250/300 15-16 Frame Protectors 250F FREE-RIDE 18-20One 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.
