POLINI Ø40 replacement ring designed for engine reconditioning of urban scooters. Designed to fit the piston PN2040975, this complete ring matches the specifications of the component delivered in the original kit, ensuring a clean and precise reassembly during a piston/ring exchange.
Ideal for workshop sessions on 50 cc two-stroke scooters (e.g., Peugeot Ludix), this ring allows for the replacement of a worn part without reassembling an incomplete element. Designed for demanding mechanics and DIY enthusiasts, it facilitates the reassembly of the piston/cylinder group while respecting the necessary clearance and alignment for the proper functioning of the engine. Be sure to check the condition of the cylinder and piston before installation and to adhere to the manufacturer's torque specifications and clearances during installation.
