NEW PISTON LINE

HIGH PERFORMANCE

2 & 4 stroke cast and forged pistons

For over 10 years now, ATHENA has been developing and producing cylinder 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 manufactured according to the latest technological standards and 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. Thanks to the use of the best raw materials in combination with the most advanced design and manufacturing methods, ATHENA high-performance pistons impress with their very low weight and high stability. This results in better engine performance and longer engine life .

4-stroke HIGH PERFORMANCE

Forged pistons

The 4-stroke HIGH PERFORMANCE forged pistons are developed, designed, and produced entirely in-house at ATHENA. To guarantee maximum piston performance, the ATHENA piston designs were extensively tested in advance both on the test bench and on the race track. The aim was also to meet ATHENA's own high standards of 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 to achieve excellent sealing properties and to prevent the "blow-by" effect (escape of combustion gases into the crankcase) while ensuring that there is no loss of sliding properties.Blow-by effect (escape of combustion gases into the crankcase) is avoided and no loss of sliding properties is accepted. The result is a considerable increase in performance combined with longer service life for the piston and cylinder.

Details&nbsp;

	Hardened stiffening bridges To increase overall strength, ATHENA HIGH PERFORMANCE pistons have hardened stiffening bridges manufactured with low tolerances. This technology results in more stable pistons that can better withstand increased engine performance with only a slight increase in weight.
	Piston pin lubrication To improve lubrication of the piston pin, special lubrication grooves are incorporated into ATHENA pistons, which allow 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 improved lubrication also increases efficiency, prevents pressure losses, and ensures constant engine power output.
