ATHENA Big Bore Cylinder Kit P400250100029 276cc for Kawasaki KX 250

The Big Bore cylinder kit of 276cc is specifically designed for the Kawasaki KX 250, offering a significant increase in engine performance. Made from high-quality aluminum alloys, this kit is the result of a cutting-edge manufacturing process that integrates advanced technologies and rigorous quality controls. Each cylinder is cast in steel molds and machined using CNC machines, ensuring micron tolerances and unparalleled precision.

Thanks to innovative 3D software, it is possible to generate virtual simulations that optimize design and mechanical strength. The water channels have been revised to improve cooling capacity, while the cylinder sleeves, made with a special blend of silicone carbide and nickel, ensure excellent durability and piston mileage. Each cylinder is tested at an internal temperature of about 20 degrees, allowing for accurate verification of bore sizes and surfaces, which are perfectly flat to eliminate any mounting inaccuracies.
