Boyesen Power Reeds - 619 Carbon valvesRef : BOY00031A / 1114570

BOYESEN Power Reeds - 619 by BOYESEN, dedicated to Cross practice. These reeds are designed around a patented two-stage architecture, with fibreglass petals, to manage intake more finely on demanding two-stroke engines.

• Design: patented two-stage structure for intake flow control.
• Material: fibreglass petals, chosen for their lightness and durability.
• Usage: suitable for competition and cross riding where intake precision matters.
• Manufacturer reference: 619 (to be checked on your machine before installation).

The BOYESEN Power Reeds aim to optimise the reed valve behaviour by refining air passage and intake responsiveness. When installed and adjusted correctly, they are a popular choice among riders seeking a more consistent flow management between low and high revs, without compromising the expected robustness in off-road conditions.
