Maybe a mouse fell into the cylinder.

Piston to cylinder wall clearance is to large - because of the cylinder being worn out.
Before throwing in a new piston, get the piston clearance # from a shop manual and check the clearance.
The cylinder may need to be re-bored.

Just normal wear and tear can do it. On an engine that small the piston is seen as a serviceable component. Make sure you let the engine warm up before thrashing it when you fit the new one, it'll last longer.

Oil supply failure or the petrol/air mixture was way too weak for too long so the engine was getting way too hot. The wrong flavour of spark plug can cause overheating too. Or the previous owner was using a dodgy fuel additive. Know of a bloke who put aviation grade petrol (102 octane) in a moped once, went like stink for about 5 miles until the engine dismantled itself.

Need more info....? Year?
How are the rings, cylinder wall, oil injected? Where's the crack? How's the skirt?
Parts for ancient bikes are mostly extinct.. you can get a new piston made..
.....I go with abuse (overheating)

over heating. When the engine gets too hot it can sieze. Happens a lot on old 2 strokes - get new piston + rebore.

The ratio you used is basically too severe of two stroke oil. do what that guy mentioned and reconnect the pump decrease back up (make beneficial it works) and unload the gasoline out or dilute it with alot of gasoline. if it nonetheless does it then unload the tank and positioned new gasoline in. If it nonetheless does it, alter the two stroke oil injector. if it nonetheless does it, you're burning crankcase oil :(.

Abuse, and Suzuki just isn't as good as Yamaha or Honda. Sorry. just my opinion. I've been riding motorcycles since 1965.

A 9.7 earthquake will fracture most pistons, if the cycle is kept in a cement parking structure.

It's an old two-stroke.
This is just something that old two-strokes do from time to time...
