Laboratory tests show that Boyesen dual-stage reeds greatly improve on the results of standard reeds, giving the intake mixture much higher velocity at all rpm. The increase in engine performance can be felt from the start right up to maximum acceleration.
The two petals on Boyesen Power Reeds are made from ultra-high-strength composite fibers.
The best champions and most experienced riders around the world always choose Boyesen as the first step in the search for more power, performance and riding enjoyment for their bikes.
Power Reeds are only compatible as a replacement for the original reed blocks.
