Piston with rings GY6 4T 125cc 52,40mm

Piston with rings GY6 4T 125 cm³ for the engine, 52,40 mm diameter. The second photo shows 52,4 mm — the same figure as in the name.

• A piston with rings is replaced together with the cylinder or after it is honed: once worn, it loses its seal, compression drops, a knock appears in a cold engine and oil consumption rises
• The second photo shows: diameter 52,4 mm, overall height 37 mm and gudgeon pin bore Ø 15 mm; the first photo has no figures
• The photo shows the kit: piston, gudgeon pin, five rings — including one toothed expander — and two circlips
• The first photo on this card matches, byte for byte, the GY6 4T 150 cm³ 57,40 mm card — so we do not describe the appearance from it; this product's own photo is the second one
• You will find just the rings for the same engine listed separately — "Piston ring set GY6 4T 125cc 52,40mm"
• There is no scale in the photo itself: no ruler and no object placed for comparison. Only the figures given in the notes tell you the size, so measure your cylinder bore
• You will recognise a worn piston by a worn-smooth side, excessive clearance in the rings and imprinted marks near the gudgeon pin bore; the rings are always replaced together with the piston

To be straight with you: the maker did not write which specific model and which years it is for, and we do not guess — write us your model and year. Before ordering, measure your cylinder bore and the diameter of your old gudgeon pin — or send a photo with a caliper: we will check it before you order.
