Why choose Athena motorcycle cylinder kits?

Athena Cylinder kits: What's included

All our motorcycle cylinder kits, consisting of cylinders, pistons, and gaskets, undergo rigorous quality tests on the bench and on the road by our expert technicians and racing teams. This validation phase allows us to offer only superior quality products to our customers.

  • Cylinders: To ensure increased surface hardness and even greater wear resistance, our thermal engine cylinders are made of aluminum coated with a nickel-silicon layer, known as "motor-nicksil." This treatment, developed by Athena, is the result of years of research and development, enabling us to provide a superior product in the market. Our cylinders are designed to last and to provide optimal performance in every condition.
  • Gaskets: With the use of selected raw materials, innovative production technologies, comprehensive testing in the design phase, and strict quality control, Athena has been a world leader in the production and design of engine gaskets and motorcycle gasket kits for over 40 years.
  • Pistons: Made with high-performance materials, transformed by reverse extrusion forging and equipped with a screen-printed surface coating of sintered molybdenum disulfide; Athena racing pistons ensure performance and reliability equivalent to original spare parts at a highly competitive price.

 

Athena Cylinder Kits: The perfect choice for every requirement

Our cylinder kits are designed to suit a variety of needs and performance levels:

  • Easy Cylinder Kits: Ideal for those looking for a simple and reliable solution, composed of standard bore cylinders and gasket series.
