Supertech Yamaha YZR-R6 23x4.46x 95mm Flat Face Titanium Exhaust Valve - Single

Crafted from titanium, this Supertech exhaust valve measures 23mm intake diameter, 4.46mm stem diameter, and 95mm overall length. The flat face design is specifically chosen for its performance characteristics in high-revving engines like the Yamaha YZF-R6. Titanium is a popular choice for performance valves because it's strong yet significantly lighter than steel, which helps reduce valve float at high RPMs and allows the engine to rev more freely.

This single exhaust valve is a direct replacement for your stock unit, designed to maintain proper sealing and airflow through the cylinder head. When rebuilding or upgrading the top end of your Yamaha YZF-R6, using high-quality valves like these can make a notable difference in engine responsiveness and reliability under demanding conditions. Ensure you have the correct valve spring and retainer combination to match the valve's specifications for optimal performance.
