This steel exhaust valve is a durable alternative to titanium, cross-referencing with OEM 5HO-12121-00. It sits in the exhaust port of the cylinder head. Steel valves offer a longer service life for riders who prioritise reliability over outright weight savings. They resist the extreme heat of the exhaust stroke better than many stock components. When fitting these to your bike, ensure your valve springs are rated for the additional weight of steel. Always lap the valve into the seat to ensure a perfect seal and restored compression during your top-end rebuild.
