VERTEX Piston Ring - Ø 55.95 mm (Manufacturer Ref: 53010005600)
VERTEX piston ring sold individually, designed as a replacement for the original for cylinders of 55.95 mm. This product is intended for motocross and off-road use, and it maintains the original dimensions for direct installation during an engine rebuild.
Compatible with several recent 125 cm3 motocross models: YAMAHA YZ 125 (2026), FANTIC XX 125 (2026), and FANTIC XE 125 (2024). Before installation, check the condition of the piston and cylinder as well as the clearances and tolerances recommended by the manufacturer. Choosing a ring with the appropriate dimensions is essential to ensure the sealing of the transfers and the proper behavior of the engine.
Replace your worn ring with a part that has original dimensions to restore proper piston/cylinder contact and facilitate the restart of the top-end. For any intervention, follow the manufacturer's assembly recommendations and torque specifications.
