Kymco UXV

Additional Notes

• The Kymco UXV 700i front differential lists two distinct capacity values: 0.27 liter for a dry fill and 0.25 liter for a service fill. The dry fill figure applies when the differential housing is completely empty, such as after a rebuild or component replacement, while the service fill figure applies during a routine fluid change where residual fluid remains in the housing.
• The same dry fill versus service fill distinction appears on the UXV 700i rear differential, where the dry fill capacity is 0.25 liter and the service fill capacity is 0.23 liter. The 0.02-liter difference between the two values reflects the volume of fluid that typically remains in the housing after draining.
• The UXV 500 (2008-2011) front differential holds 0.28 liter and the rear holds 0.25 liter. Neither position lists separate dry and service fill values, meaning a single capacity figure applies regardless of whether the housing is fully empty or partially drained.
• The UXV 500i (2011-2018) front differential capacity is 270 CM3 and the rear is 250 CM3, which are numerically equivalent to the 0.27-liter and 0.25-liter dry fill figures on the UXV 700i, though the 500i specifications do not distinguish between dry and service fill volumes.
• The UXV 450i (2014- ) shares the same front and rear differential capacities as the UXV 500i, at 270 CM3 and 250 CM3 respectively, but the 450i normal-use change interval is 2000 km or 12 months, which is half the 4000 km interval specified for the UXV 500i under normal use.
• The UXV 500 (2008-2011) carries the longest normal-use change interval among the listed variants at 4000 km or 12 months for both front and rear differentials, a figure matched by the UXV 500i but not by the 450i or 700i.
• The UXV 500i (2011-2018) is the only variant in the specifications that includes a fluid level check interval separate from the change interval. Under normal use, both front and rear differentials call for a check at 2000 km or 6 months, with the full fluid change due at 4000 km or 12 months.
• Initial service intervals differ between model groups. The UXV 450i and UXV 700i both specify an initial fluid change at 150 km or 1 month for both front and rear differentials, while the UXV 500 and UXV 500i specify an initial change at 300 km with no accompanying time limit stated for that condition.
• The initial service interval represents a break-in fluid change intended to remove metal particles generated during the early wear-in period of new gear surfaces. On the UXV 500 and UXV 500i, the 300 km initial change threshold is twice the distance required on the UXV 450i and UXV 700i, where the threshold is 150 km.
• Across all four UXV variants, the rear differential capacity is consistently lower than the front differential capacity. The front holds 270 CM3 or 0.27-0.28 liter depending on variant, while the rear holds 250 CM3 or 0.23-0.25 liter, reflecting a smaller housing volume at the rear axle position.
