ATHENA Cylinder Kit P400510100001 400cc without head

The 400cc cylinder kit without a head is designed to deliver high performance and reliability over time. Made from high-quality aluminum alloys, this cylinder is the result of advanced technologies and a cutting-edge manufacturing process, ensuring millimeter tolerances at every stage of production.

Each cylinder is coated with a nickel-silicon alloy, increasing wear resistance and improving the overall lifespan of the component. The design includes optimized water channels to maximize cooling capacity, while the liners are made from a special silicone carbide, ensuring a long life for both the piston and the cylinder itself.

The kit includes two base cylinder gaskets, with specific thicknesses for different models: 0.2 mm for DR-Z 400 and KLX 400, and 0.7 mm for LT-Z 400 and KFX 400. Thanks to rigorous quality control, each cylinder is tested to ensure excellent performance, with a maximum power of 44.1 HP at 9,700 RPM and a compression ratio of 12.2:1.

With a bore of 90 mm and a stroke of 62.6 mm, this cylinder is designed to provide immediate response and consistent power, making it ideal for motorcycle enthusiasts looking to enhance their vehicle's performance. The perfectly flat surface of the cylinder eliminates any fitting inaccuracies, ensuring simple and precise installation.
