Description:

The Harley-Davidson Aermacchi SX 250CC cylinder head is a crucial component of the two-stroke, single-cylinder, dirt bike engine manufactured between 1975 and 1978. This authentic Harley-Davidson part is known for its durability and high-performance capabilities.

The cylinder head houses the combustion chamber and is responsible for the efficient transfer of heat away from the engine.

The cylinder head is made of high-quality aluminum alloy, which is both lightweight and robust. Its finish is smooth and polished, giving it an attractive appearance. The head's gasket surfaces are engineered to provide a perfect seal, ensuring optimal compression and minimizing exhaust gas leakage.

The intake and exhaust ports on the cylinder head are designed for optimal flow, ensuring efficient gas exchange. The intake port's shape and size are optimized for the intake system, while the exhaust port's design facilitates efficient exhaust gas expulsion.

The cylinder head is equipped with two valves: an intake valve and an exhaust valve. Both valves are made of high-quality stainless steel and are precision-machined for a perfect fit. They feature adjustable valve clearances, allowing for fine-tuning of the engine's performance.

The cylinder head also comes with new valve guides and seats, ensuring a proper seal and minimizing the risk of leaks. The head gasket is included in the package, making this a complete cylinder head replacement kit.

In conclusion, the Harley-Davidson Aermacchi SX 250CC 1975-78 cylinder head is a high-quality, durable component that is essential for the optimal performance of your dirt bike engine.
