Description
To better manage the displacement and to fully exploit the engine performance, Athena has developed a specific power valve system for Athena and OE cylinder kits.
The design and materials used ensure excellent power delivery even at low and medium revs.
Athena engine valves meet the highest quality requirements: they are made of aluminum alloy and steel to withstand the high thermal and mechanical stresses to which are continuously submitted.
Athena engine valves meet the highest quality requirements and follow the same specifications and tolerances as the original ones.
Athena engine valves can be installed without any modification to the original distribution components such as valve springs, seals, plates and cotters.
