Additional Notes

  • All five MotorHispania RX variants listed — the RX 125 R, RX 50 R, RX 50 Racing, RX 50 Super Racing, and RX2 50 — share an identical cooling system capacity of 0.7 liter under normal use conditions.
  • A cooling system capacity of 0.7 liter is characteristic of small-displacement liquid-cooled engines, where the total coolant volume circulating through the engine, radiator, and connecting hoses is kept minimal due to the compact engine architecture.
  • The capacity figure of 0.7 liter represents a service fill measurement, reflecting the amount of coolant required to properly fill the cooling system during a standard drain and refill procedure.
  • The RX 50 R and RX 50 Racing share both the same 50cc displacement and the same 0.7 liter cooling system capacity, with both variants introduced from 2003 onward.
  • The RX 50 Super Racing, introduced from 2007, retains the 0.7 liter cooling system capacity despite being a higher-specification variant within the 50cc lineup.
  • The RX2 50, introduced from 2005, carries the same 0.7 liter cooling system capacity as the other 50cc models, indicating a consistent cooling system architecture across the RX 50 family.
  • The RX 125 R, the sole 125cc variant among the listed models, shares the 0.7 liter cooling system capacity with all four 50cc variants, suggesting a similarly compact liquid-cooling circuit despite the larger engine displacement.
