Boyesen Carbon valvesRef : BOY00063A / 1021056

Boyesen Superstock Reed Valves (manufacturer part number: SSFT133): replacement reeds designed for vintage and motocross enthusiasts who want to achieve a clean and responsive intake on their Yamaha TY. Made from reinforced fibre, these reeds fit in place of the original parts for a quick restoration of the intake system.

• Direct replacement: size and footprint compatible with original reeds for easy installation.
• Improved sealing: design that limits sealing losses at the reed tips, contributing to a healthier intake.
• Intake responsiveness: the fibre allows for controlled flexibility of the reeds, promoting a sharp engine response at low and mid-range RPMs.
• Durability: wear-resistant material suitable for the demands of motocross and off-road riding.

These Boyesen reeds are particularly aimed at owners of Yamaha TY (e.g. TY 80 and TY 175) who are looking for a reliable part to restore or optimise their intake performance. Before installation, check the condition of the cage and sealing surfaces and replace the gaskets if necessary to ensure the best sealing.
