The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
ADX 125 E5, TEA12T1CN-EU (2023- )
  • Use: Normal
  • Capacity 430 CM3
  • Capacity 75-150 CM3 (Reservoir)

Additional Notes

  • The SYM ADX 125 E5 (TEA12T1CN-EU) cooling system holds 430 CM3 as the main circuit fill capacity, a figure that reflects the total volume of coolant the system circulates through the engine and radiator under normal operating conditions.
  • A separate reservoir capacity of 75-150 CM3 is specified alongside the main 430 CM3 figure, indicating the overflow or expansion tank operates within that range rather than at a fixed volume.
  • The 430 CM3 main capacity is relatively modest, consistent with the small-displacement liquid-cooled single-cylinder architecture typical of 125cc scooter engines, where cooling circuit volume is kept compact by design.
