The manufactory write:
The tight collaboration with popular Worldwide Racing Teams and the long-time experience achieved
by our technicians, enable Athena to offer the most complete and tested range of off-road/ATV cylinder kits
now available in the worldwide market. The Athena R&D staff has taken great care in designing and
choosing the materials of our 2/4-stroke cylinders for off-road and ATV’s. Athena’s cylinder kits, as OEM spare
parts, assure the best performances thanks to the different shape and timing of the portings, the increased
volume of the coolant inside the relevant water jackets and the special materials used on each component.
All our cylinder kits undergo a special treatment of Nickel-carbide coating, which guarantees a longer working
life of the cylinder, thanks to its hardness. The honing and lapping processes performed on the cylinder liner
ensure a greater fluidity and lubrication of the piston. All mechanical processing on our cylinders, heads and
exhaust valves are carried out by state-of-the-art CNC machineries, which enable us to achieve the highest
quality standards. Athena’s kits include pistons, expressly designed to give the best performances to the
cylinder components. Gaskets as well are designed to assure the best sealing and lasting over the years. For
the most demanding customers Athena offers also cylinders with overbore kit diameter to get more power!
