Ferrea 1999 Yamaha YZ 400F 5 Valve 28.96mm Head Dia Competition Exhaust Valve - Set of 2

This set includes two Ferrea competition exhaust valves, each with a 28.96mm head diameter, designed for the 1999 Yamaha YZ 400F's 5-valve engine.

Ferrea valves are known for their robust construction, often using high-grade materials like stainless steel or specialized alloys to withstand the demanding conditions inside an engine. These competition valves are built to handle higher temperatures and pressures than stock components, making them a solid choice for performance-oriented builds or when replacing worn-out original parts. The precise machining ensures a good seal against the valve seat, which is critical for maintaining compression and engine efficiency.

When rebuilding or upgrading the top end of your 1999 YZ 400F, ensuring you have reliable valves is key. This set provides the exhaust valves needed to get your engine running strong again.
