The STD 54.00 mm Y-BOX piston kit is designed for a moped with a 125 cm3 Alpha engine and is a set of spare parts that are required to repair or replace the piston system in this moped. This kit includes the following parts:
• Piston: A piston is a cylindrical part that moves inside an engine cylinder and is responsible for compressing the mixture of fuel and air and transferring energy from the combustion of fuel to the crankshaft. Its diameter is 54.00 mm and corresponds to standard sizes.
• Rings: Piston rings (5 pieces) are designed to provide a tight seal inside the cylinder and prevent leakage of the compressed mixture. They are placed on the piston and fit tightly to the cylinder walls.
• Piston Pin: The piston pin is the bushing that connects the piston to the connecting rod. It allows the piston to move up and down inside the cylinder.
• Snap Rings (2 pieces): Snap rings help hold the piston pin in place and prevent it from slipping out.
The purpose of using this kit is to replace worn or damaged components in the piston system of the Alpha 125cc moped. The piston, rings, piston pin and circlips are key components within the engine and their proper function is critical to efficient combustion, power transmission and reliable engine operation.
Replacing the piston system using this kit helps restore your Alpha moped's performance, extend its life and provide a more reliable and economical ride.
