Banshee Boyesen Reeds

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.

Minor change give major HP improvements.

Faster opening and closing.

Greater low pressure (low-throttle) response.

Greater velocity and flow area.

Longer overall life.

No engine damage if broken.

Note: For stock replacement ONLY.

Dual-stage reeds work in unison to perform efficiently throughout the entire powerband. The difference in stiffness between the top reed and the bottom reed allow the reeds to respond quickly and accurately to changes in engine pressure. This translates into quicker acceleration, crisper throttle response and increased horsepower throughout the powerband.
