• The pistons are made of aluminium alloy, which withstands heat and is highly conductive.
• The offset pistons are used to reduce piston-slapping noise.
• To prevent the piston from being reassembled in the wrong direction, the front mark (←) is on the piston.
• The piston has valve recesses on the intake side.
• Pistons and connecting rods cannot be disassembled because they are shrinkage fit.
