Custom Design Pistons

The piston is one of the biggest factors that determine the performance of an engine. The volume of the piston top is determined to obtain a high compression ratio to generate high torque, and the valve recess diameter is determined to match the valve diameter used. In addition, a shape that creates a tumble is designed to suck in more air. Furthermore, the compression height is changed according to the amount of surface grinding of the cylinder block, and a high-strength piston pin is set to suppress deformation at high revolutions.
