Electronic Innovation with GET Boost: Included in the kit is the GET Boost electronic module, developed by Athena’s GET division, which takes your Kawasaki KX 250’s performance to the next level. GET is globally recognized for its collaborations with top off-road teams, including MXGP and AMA Supercross.

The GET Boost module, pre-calibrated specifically for this cylinder kit, connects quickly and allows you to get the most out of your engine safely and reliably.
Cylinder Technical Specifications: The cylinder is made from a high-silicon aluminum alloy with an integrated steel bore through Athena’s exclusive co-fusion process. This process ensures a perfect bond between the aluminum and steel, improving heat transfer and preventing premature wear. The bore geometry is designed to ensure a perfect combustion seal, preventing pressure loss and fluid or gas leaks.
High-Performance Forged Piston: The forged piston, crafted from aluminum alloy, combines strength and lightness. CNC machining ensures tight tolerances and precise geometries, with a molybdenum disulfide coating that reduces friction and noise. The aerospace-grade steel pin, coated with DLC, guarantees hardness and low friction for unparalleled durability and reliability.
High-Quality Gaskets: The included gasket set is designed to provide optimal sealing with the new cylinder. The head gasket is an MLS (Multi-layer Steel) type, made from stainless steel and laser-cut with the latest technology, ensuring perfect and long-lasting adherence under all conditions.
