Athena cylinder set
For more than 10 years, Athena has been investing in the best and most advanced technologies for producing cylinders and their components, which are used not only by OE manufacturers, but also by the best racing teams in the world.
The manufacture of aluminum cylinders is constantly improved by working with the best Italian universities as well as the continuous development of the best engine tuners.
Due to a flexible production department, Athena can react efficiently to different situations (production batches of OE manufacturers, small quantities, construction of 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. Once all the cylinders have passed the strict quality controls, they meet the highest standards of reliability, longevity and performance.
