KYMCO UXV 500i Service Specs: Part Numbers and Intervals

September 23, 2026 Michal B., KYMCO parts specialist

This is the service sheet for the KYMCO UXV 500i (4-stroke single, liquid cooled, 498.5 cc, fuel injected). It lists the battery, spark plug, filters, belt and the rest, each figure with the genuine KYMCO part number for the model years in our catalog (2016-2017) and the diagram the part is drawn on. The figures are KYMCO service data from the KYMCO UXV 500 / 500i service manual (2009-2018). When this page and your own manual disagree, the manual wins.

What to know before you order

The UXV 500i shares its engine, CVT (34.1 mm belt, 30 mm rollers) and YTX20L-BS battery with the MXU 500i. It takes 3.0 L of SAE 5W-50 at an oil change, and 270 cc front and 250 cc rear of 80-90 gear oil. The UXV manual gaps its CR7E plug at 0.8 to 0.9 mm.

UXV 500i maintenance intervals

Whichever comes first, distance or time. The first service is the one riders skip and the one that matters most on a new or rebuilt engine.

Item	Interval
Engine oil, strainer, filter	at 150 km (90 mi), then every 1,000 km (600 mi) or 6 months
Front and rear drive gear oil	replace every 2,000 km (1,250 mi) or 12 months
Drive belt	check every 2,000 km (1,250 mi) or 12 months
Air filters	clean every 1,000 km (600 mi) or 6 months
Spark plug	every 1,000 km (600 mi) or 6 months

Torque for the parts you replace

Clean, dry threads unless the row says otherwise. Aluminium cases strip long before a steel bolt complains, so use a torque wrench on the drain bolt and the plug.

Fastener	N·m	ft-lb
Spark plug	12	8.7
Engine oil drain plug	25	18
Oil filter cartridge (oiled)	9.8	7.2
Drive pulley nut (oiled)	137	101
Wheel nuts	54	40
Wheel hub to CV joint nuts	196	145
Caliper bracket bolts	26	20

Electrical test values

Measured at about 20 °C with the connector unplugged. A reading far outside the range points at the part; a reading inside it sends you back to the wiring and the connectors.

Part	Test value	Genuine part number
Ignition coil	primary 0.55-0.75 Ω	3051A-LKC3-E00 Ignition Coil Assembly
Fuel injection	injector 10.6-15.9 Ω; fuel pump 300 ± 10 kPa (43.5 psi)	3920A-LKC3-E00 Module Ass'y. ECU

Which model year do I have?

The year decides which number is yours where a row lists more than one. Decode your VIN with the VIN lookup, or read the model code on the frame plate, then open that year's diagrams from the model list.
