Technical Details

  • Boyesen's revolutionary dual-stage reed design delivers more usable power than stock.
  • Your original one-stage reed operates most effectively only within a narrow RPM range.
  • 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.
  • Dual stage reeds.
