The pistons must be removed from the cylinders to replace the rings. Therefor, you must disconnect the rods from the crank. No options no alternatives period
The pistons and connecting rods have to be disconnected from the crankshaft, then removed from the top of the engine block. The oil pan and heads will have to be removed to gain access.

The rings are like a gasket between the engine and the pistons. explosions happen in the engine which push the pistons to turn the engine and keep it going. If the rings are bad the explosion escapes and doesnt push pistons like its supposed to and engine wont run.
Quite simply you have to remove the pistons. first drop the oil pan second disconnect connecting rod end caps third either remove crankshaft or remove cylinder heads then finally remove pistons. removing pistons are commonly removed from the bottom of the engine. they are pushed out of the top where the cylinder heads sit. Once removed you can replace the rings and then you have to get a piston ring compressor to reinstall the pistons.
Broke rings on pistons
pistons rings are damages, because1. Lack of lubrication2. Engine over heating
Changing the pistons will NOT fix an oil problem UNLESS you have a hole in the piston, which would cause many more problems as well. Placing new rings on the pistons, along with honing the cylinder walls (which is necessary if you are replacing rings) WILL allow the cylinder to seal better, improving compression and stopping oil slipping past the oil ring. It would be wise to check valve guides and seals as well if you decide to change the rings.
Most kids will out grow the bike long before. It will ever need a motor rebuild.
To replace the oil rings on a Daewoo Matiz, first ensure the engine is cool and disconnect the battery. Remove the cylinder head and pistons, then carefully take out the old oil rings from the pistons. Install the new oil rings, ensuring they are properly seated and aligned, then reassemble the pistons and cylinder head. Finally, reconnect the battery and check for leaks before starting the engine.
You probably have bad rings in at least one of your pistons.
