Supertech Kawasaki Ninja ZX12 29.30 (+1mm)x4.95x 98.4mm Inconel Exhaust Valve - Single

Supertech is known for making well-built engine components, and this Inconel exhaust valve is a solid example. This specific valve is designed for the Kawasaki Ninja ZX12 and measures 29.30mm in diameter, which is a +1mm oversize compared to stock. The 4.95mm stem and 98.4mm overall length are also key dimensions for proper fitment in the cylinder head.

The material used here is Inconel, a high-nickel alloy that's exceptionally resistant to high temperatures and corrosion. This makes it a great choice for exhaust valves, which are exposed to the hottest gases in the engine. Using an oversized valve like this can help improve sealing and potentially boost performance, especially if you're rebuilding or modifying the engine.
