ATHENA Complete standard cylinder kit 250CC 756.00.59

Athena cylinder set

For more than 10 years, Athena has been investing in the best and most modern technologies for the manufacture 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 collaboration 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 taking into account the latest technologies and coated with a nickel-silicon alloy. After all cylinders have gone through rigorous quality checks, 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

- The cylinder liners consist of a special mixture of silicon carbide and nickel to ensure the best piston running performance and cylinder durability.

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

- Cylinder surfaces are completely flat to eliminate any inaccuracies of fit
