NEW PISTON LINE HIGH PERFORMANCE 2 & 4 Stroke CAST-LITE / FORGED For over 10 years, Athena has designed and manufactured cylinder kits for off-road 2&4 Stroke bikes. Working with the world s best Motocross Race Teams, Athena has engineered a new line of racing pistons - HIGH PERFORMANCE. Athena offers a full range of racing pistons, specifically designed for all off-road bikes (MX and ATV) available in Cast-lite or forged for 2 & 4 Stroke engines. Athena s new HIGH PERFORMANCE pistons are engineered and produced with the latest technologies and hold the industries tightest tolerances. The unique Smart can packaging, features a reusable metal canister which can be recycled or can be used for storage. All Cast-lite and forged piston are produced using aluminum alloys that have the perfect balance of nickel, copper and silicon. The best choice of premium raw material combined with advanced engineering and production methods results in Athena s HIGH PERFORMANCE pistons offering exceptional characteristics of lightness and endurance. The result is better engine performance and durability. 5-time MX World Champion, Tony Cairoli RED BULL KTM FACTORY RACING TEAM
4-STROKE HIGH PERFORMANCE FORGED PISTONS The 4 Stroke HIGH PERFORMANCE Forged Pistons are entirely engineered, developed and produced in our facilities. Engineered designs are initially tested on the test bench and then on the track to guarantee higher performance, according to our strict parameters of reliability and durability. Special attention is given to the choice of compression segments and oil-scrapers. These are selected based on their tangential loads and shape to guarantee excellent sealing, avoiding the blow-by effect, but without compromising the sliding. The result is a respectable power increase combined with longer durability of the piston and cylinder. Hardened Bridges Athena s HIGH PERFOR- MANCE pistons feature hardened bridges that have close tolerances and obtain maximum rigidity. The result is a stronger piston to handle the increase power with minimal weight increase. Accumulation groove Athena s HIGH PERFORMANCE pistons feature an oil accumulation groove, located between the first and second sealing ring. This groove allows for the accumulation of oil, stabilizes the pressure between the rings, and helps prevent compression blow-by. The increase in lubrication improves efficiency, prevents pressure losses, and ensures consistent engine performance. Piston pin lubrication To increase the lubrication of the piston pin, we incorporate a groove that allows for the accumulation of oil inside the pin bore. The result is reduced friction, lower temperatures and reduction of overheating and/or seizing.
2-STROKE HIGH PERFORMANCE CAST-LITE & FORGED PISTONS Cast-lite Pistons Athena s Cast-Lite HIGH PERFORMANCE Pistons are lighter then original OEM design. Tight tolerances and piston ring design reduce friction while mainting durability. They are the right choice for small displacement 2-stroke engines where weight is the key factor for performance. Forged Pistons Athena s Forged HIGH PERFORMANCE Pistons are designed for larger displacement engines and small displacement engines with higher compression ratios. They are the right choice when very tight tolerances, minimized friction loss and predictable expansion are desired. Lightening and balancing hole These holes, bored during milling or obtained during casting (only for the cast-lite pistons), enable to reduce the friction between cylinder and piston. Surface treatments Athena HIGH PERFOR- MANCE Pistons are subjected to special surface treatments when appropriate. This includes tin plating or PTFE (Polytetrafluoroethylene) coating. The result is less friction, improved sealing, and faster break in. Lubrication ports Both Cast-lite and Forged HIGH PERFORMANCE Pistons incorporate additional oil passages in the bottom of the piston over the OEM design. The result is improved lubrication and cooling for both the piston and the piston pin.
NEW GASKET LINE RACE GASKET Another big change in our OFF-ROAD catalog is the new line of RACE GASKET designed for competition: Athena has specifically designed this RACE GASKET for the Pro, Semipro, and Amateur riders who freshen up their engine prior to a race series or during mid season. The kit will include a top of the line MLSS (Multi Layer Stainless Steel) Head Gasket and two premium quality base gaskets, one of which has a reduced thickness of 0.1 mm, to optimize engine compression ratios. This new composition gives the rider/technician a choice to increase compression and decrease the squish in order to get better performances. It is all in one kit! Our RACE GASKET kits are very competitively priced and supplied in a captivating packaging. These are sure to be a strong seller in the marketplace!

SUPERIOR PERFORMANCE THROUGH INNOVATION Raw Materials Each Head Gasket configuration utilizes the best raw materials available, such as AISI 304 Stainless Steel. Athena utilizes state of the art processing such as in-line laser cutting and multi-stage stamping technologies. With our Multi-Layered Steel (MLS) Head Gasket, each layer is individually blanked and formed specially to optimize performance. Optimized Embossing Formation Through multi stage processing, our embossing process optimizes the radius in the bend areas. The result is reduction in stress points, improved conformability, and superior wet-out (contact area) that is superior to the competition. Our technology also provides a consistent inner flange spacing of (minimum 1 mm) from the edge to the embossed start point. This results in a superior seal in the embossed areas. Stress Stabilization & Relaxation This proprietary tempering process significantly reduces forming induced stresses. Pre-coated metal (used by competition) would not be able to survive this stabilization process. Advantages of a tempered metal are reduced hardness and brittleness, increased flexibility and deformation retention. This process dramatically increases the long term durability and reliability of each head gasket. Proprietary Coating Technologies Four different layers are used to provide the ultimate seal between the head and block mating surfaces. These coatings will normally eliminate the need for additional deck surfacing, Our coating processing provides 100% encapsulation of all exposed metal, far superior to the competition that has exposed raw steel on the edges. The layers include Fluoroelastomer (FKM) for extreme temperature and chemical resistance. This technology provides superior conformability, oxidation resistance, and better removability, even after extreme temperature exposure.
