Super Stock BOYESEN Carbon Reed Valves - Manufacturer's ref: SSC000

Designed to replace the original reeds on Cross machines, these Boyesen Super Stock carbon reeds offer a robust and lightweight alternative for the reed valve. Made from a reinforced composite, they combine rigidity and flexibility in the petals for a sharper closure and better sealing compared to worn elements.

• Direct replacement for original reeds, plug-and-play installation without major modifications.
• Carbon/composite construction for increased resistance to deformation and fatigue.
• Careful finishing to limit intake leaks and improve reed consistency over time.
• Ideal for Cross riders seeking reliability and performance consistency in demanding conditions.

These reeds are particularly suited for Honda CR80R models; be sure to check the exact compatibility with your machine's year and version before ordering. Boyesen reeds are renowned in competition for their longevity and lively response during opening/closing — they aim to optimise intake responsiveness without altering the engine mapping.
