Ferrea 00-03 Yamaha YFM 660 Raptor 32mm Head 5.95mm Stem Dia Competition Exhaust Valve - Set of 2

These are Ferrea competition exhaust valves, designed for the 2000-2003 Yamaha YFM 660 Raptor. They feature a 32mm head diameter and a 5.95mm stem diameter, making them a solid choice for anyone rebuilding or upgrading their engine's top end. When you're working on the cylinder head, the valves are critical for controlling airflow into and out of the combustion chamber. Using well-built valves like these can help ensure proper sealing and efficient operation.

Ferrea is known for making strong valvetrain components. These particular valves are built for competition use, meaning they're made to handle the demands of higher performance applications. The 32mm head size is a common upgrade for the Raptor 660, offering a bit more surface area for better airflow compared to stock. The 5.95mm stem diameter is also a specific dimension to ensure they fit correctly within the valve guides and work with compatible valve springs and retainers.

This set includes two exhaust valves. If you're rebuilding your engine, it's always a good idea to inspect all your valvetrain components. Having a matched set of quality valves can contribute to a smoother running engine and improved performance.
