Piston rings HONDA DIO STD 39,00mm

HONDA DIO piston rings, 39,00 mm diameter. The size is taken from the name.

• Piston rings seal the combustion chamber and scrape oil off the cylinder wall; when worn they let pressure through – compression drops, oil consumption rises and blue smoke comes from the exhaust
• These are two-stroke engine rings: their height "H" is marked on the photo itself, and it is exactly the height that is missing from the name
• THREE rings in the photo: the top one is marked H 1,2 mm, the second – H 1,5 mm, and the third lies apart and is a thin expander ring
• This is the only one of the three 2T sets in this list with rings of two different heights – 1,2 and 1,5 mm; in the other two, all rings are 1,5 mm
• Its own photo: there is nothing shared with the other listings here
• The same 39,00 mm diameter also appears in "Piston HONDA DIO AF 18 - 39,00 SEE TW" and "Piston with rings GY6 4T 50cc 39,00mm"
• In the name there is a non-breaking space between "DIO" and "STD", and no space at all after "STD" – when searching, copy the name exactly as it is
• Rings on their own are needed when the piston is still sound – if the piston is worn too, take the piston with rings: it is sold with the same rings in one set
• You can tell a worn ring by too large a gap at the joint and by it falling freely inside the cylinder; the whole set of rings is replaced at once, not one at a time

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