VERTEX Ring Set Ø40 25
Replace the worn rings in your engine with this VERTEX set specifically designed for cylinders with a diameter of 40 mm. Designed for the routine maintenance of scooters and small urban motorcycles, this set helps restore the seal between the piston and cylinder sleeve to achieve clean engine operation.
This VERTEX pack is aimed at riders who maintain their 50 cc: before installation, check the diameter of the sleeve (Ø40 mm) and the condition of the piston. A change of rings is necessary when compression decreases, smoke increases, or acceleration becomes jerky.
Installation tips: measure the gap at the cut, check for ovalization of the sleeve, degrease the seating surfaces, and adhere to the tolerances recommended by the manufacturer. If in doubt, entrust the installation to a specialized workshop to ensure a safe commissioning.
