NEW PISTON LINE

HIGH PERFORMANCE

2 & 4 Stroke cast and forged pistons

For over 10 years now, ATHENA has been developing and producing piston kits for 2 & 4-stroke off-road motorcycles. In collaboration with the world's best motocross racing teams, ATHENA has now designed a new line of racing pistons –

HIGH PERFORMANCE.

ATHENA offers a wide selection of 2-Stroke and 4-Stroke racing forged and cast pistons, which are specially designed for all off-road motorcycles (MX, Enduro, and ATV). They are produced according to the latest technological standards and the highest industrial requirements. The unique "Smart Can" packaging, consisting of a resealable metal can, can either be used as a storage container or recycled.

All ATHENA cast and forged pistons are made of an aluminum alloy with a perfectly balanced composition of nickel, copper, and silicon. By using the best raw materials in combination with the most advanced design and manufacturing methods, ATHENA high-performance pistons impress with their very light weight and high stability. This results in better engine performance and longer engine life .

4 Stroke HIGH PERFORMANCE

Forged Piston

The 4-stroke HIGH PERFORMANCE forged pistons are developed, designed, and produced entirely in-house at ATHENA. To guarantee maximum piston performance, ATHENA piston designs were extensively tested in advance both on the test bench and on the racetrack. The aim here was also to meet ATHENA's own high standards for durability.

Particular importance was attached to the selection of compression rings and oil scraper rings. Taking into account the tangential loads and tangential profiles, these were selected in such a way that, on the one hand, excellent sealing properties are achieved and, on the other hand, the "Blow-by" effect (escape of combustion gases into the crankcase) and, on the other hand, no loss of sliding properties. The result is a considerable increase in performance combined with longer durability of the piston and cylinder.

details

	Hardened stiffening bridges To increase overall strength, ATHENA HIGH PERFORMANCE pistons feature hardened stiffening bridges manufactured to low tolerances. This technology results in more stable pistons that can better withstand increased engine power with only a slight increase in weight.
	Piston pin lubrication To improve piston pin greasing, special greasing grooves are incorporated into ATHENA pistons, allowing oil to accumulate in the area of the piston pin bore. This results in reduced friction, lower temperatures, and a lower risk of overheating and/or piston seizure.
	oil lubrication groove ATHENA's HIGH PERFORMANCE pistons have an oil lubrication groove between the first and second sealing rings. This groove allows lubricating oil to accumulate, thereby stabilizing the pressure between the piston rings and preventing the "blow-by" effect. The improvement in greasing also increases efficiency, prevents pressure losses, and ensures constant engine power output.
