VERTEX Ring Set Ø39.915MM
Replace the worn rings in your 2-stroke engine with this VERTEX ring set, specially sized for a piston diameter of Ø39.915 mm. The rings ensure a seal between the piston and the cylinder, playing a key role in compression and gas expulsion — essential elements for the proper functioning of an urban scooter and city acceleration.
Ideal for routine maintenance or during disassembly/piston replacement, this ring set allows for the restoration of sealing and limits compression losses related to worn rings. Installation and checking of axial/conical play are recommended to ensure optimal operation after replacement. Be sure to check the condition of the piston and cylinder before reassembly to ensure proper seating of the new rings.
