Single cylinder 50cc 5-sided LC water-cooled for Piaggio engines from 1998, NRG, ZIP

Single cylinder 50cc pentagonal LC TECHNICAL DATA: - 50cc cylinder - can be used as a replacement for the original cylinder - 40mm bore IMPORTANT NOTES: Experienced mechanics recommend changing the coolant at the same time when changing the cylinder, as this deteriorates after about two years and may clump, clogging seals or fins. However, make sure you use the correct coolant. The rule of thumb is: never mix silicate-containing with silicate-free coolants. Often, however, it is no longer possible to determine which coolant was used, and a complete fluid change is almost impossible because components have built up in the lines. Therefore, play it safe by using a universal, state-of-the-art coolant that can be mixed with all coolants, e.g., Agip Antifre...
