It appears Zongshen kept the TW200 engine bore, and increased the stroke to gain the extra 34cc engine displacement.  Therefore, TW200 pistons, and piston rings should work in the 230cc, Zongshen engine. However, the connecting rod, cylinder, and cylinder head might be unique to this motorcycle. Also, the engine might be 5.5mm taller. A taller engine might require slight modification to the upper engine mounting plates if you wished to mount this engine in the 200GY-2, or Yamaha motorcycles.
