Additional Notes

  • The Kymco MXU 500i front differential carries two distinct capacity values: 270 cm³ for a dry fill and 250 cm³ for a service fill. The dry fill figure applies when the housing has been fully drained or disassembled, while the service fill figure accounts for residual fluid that remains in the housing during a routine change.
  • The same dry-fill versus service-fill distinction appears in the MXU 500i rear differential, rated at 250 cm³ dry and 230 cm³ for service, and in both differentials of the MXU 700i, where the front measures 0.27 liter dry and 0.25 liter on service, and the rear measures 0.25 liter dry and 0.23 liter on service.
  • The MXU 400 and MXU 500i share an initial service interval of 300 km for both front and rear differentials. At that mileage, the break-in fluid, which may contain fine metallic particles from initial component wear, is replaced before the standard change schedule begins.
  • The MXU 700i initial service interval is set at 150 km or 1 month for both differentials, a shorter threshold than the 300 km specified for the MXU 400 and MXU 500i.
  • The MXU 500 (2007-2011) front differential initial service entry specifies a check at 150 km or 1 month rather than a fluid change, distinguishing it from the MXU 400 and MXU 500i, which call for an outright change at their respective initial service points.
  • Under normal use conditions, the MXU 375 and MXU 450i share a 48-month change interval for both front and rear differentials, with an additional monthly check interval specified alongside. No distance-based trigger is listed for either model.
  • The MXU 400 normal-use change interval is set at 4,000 km or 12 months for both differentials, combining a distance threshold with a time limit. Whichever condition is reached first would govern the service event.
  • The MXU 500 (2007-2011) front differential normal change interval is 2,000 km or 12 months, half the distance threshold of the MXU 400 despite both being naturally aspirated ATV variants within the same MXU lineup.
  • The MXU 500i normal-use schedule adds a check interval of 2,000 km or 6 months alongside a change interval of 4,000 km or 12 months for both differentials. The intermediate check at the halfway point allows condition monitoring without a full fluid replacement.
  • The MXU 700i normal change interval of 2,000 km or 12 months matches the distance figure of the MXU 500 (2007-2011) but differs from the MXU 500i, which extends the change interval to 4,000 km under normal use.
  • Front differential capacities are consistently higher than rear differential capacities across all MXU variants in the specifications. On the MXU 375, the front holds 0.27 liter against 0.25 liter at the rear, a 20 ml difference that also appears in the MXU 400, MXU 500i, and MXU 700i pairings.
