ATHENA cylinder kit for engine 290CC BIG BORE 756.00.21

Athena cylinder set

For more than 10 years, Athena has invested in the best and most advanced 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 being improved thanks to collaboration with the best Italian universities and constant development requests from the best engine tuners.

Thanks to a flexible production department, Athena can respond effectively to different situations (original equipment manufacturer 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. After passing strict quality controls, all cylinders meet the highest standards of reliability, durability and performance.

Characteristic:

- Special 3D software is capable of generating virtual simulations and mechanical loads

- The aluminum cylinders are cast in steel molds and manufactured using CNC machines (which makes it possible to guarantee tolerances of thousandths of a millimeter in all phases of production)

- Review of water channels to increase their capacity

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

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

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