ATHENA cylinder kit for engine 280CCM BIG BORE 756.41.49

Athena cylinder set

For more than 10 years, Athena has been investing in the best and most modern technologies for the production of cylinders and their components, which are used not only by original equipment manufacturers, but also by the best racing teams in the world.

Last but not least, the production of aluminum cylinders is constantly improved through cooperation with the best Italian universities and constant development requests from the best engine tuners.

Due to a flexible production department, Athena can react efficiently to different situations (OEM production batches, small quantities, building a prototype for racing teams).

Athena cylinders are made of high quality aluminum alloys. They are manufactured using the latest technologies and are coated with a nickel-silicon alloy. Once all cylinders have passed strict quality controls, they meet the highest standards in terms of reliability, durability and performance.

Features:

- A special 3D software is able to generate virtual simulations and mechanical loads.

- Aluminum cylinders are cast in steel molds and manufactured with CNC machines (thousandths of tolerance can therefore be guaranteed in all manufacturing phases)

- Revised water channels to increase capacity

- Cylinder liners are made from a special blend of silicon carbide and nickel to ensure the best possible piston life and cylinder durability.

- Tested at an internal temperature of approximately 20 degrees, for the best possible control of the holes and cylinders

- The surfaces of the cylinders are perfectly flat to eliminate any inaccuracies of fit
