KYMCO MXU 700 Service Specs: Part Numbers and Intervals

Michal B., KYMCO parts specialist

This is the service sheet for the KYMCO MXU 700 (4-stroke single, liquid cooled, 694.6 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 (2016-2026) and the diagram the part is drawn on. The figures are KYMCO service data from the KYMCO MXU 500i / 700i service manual (2013-2018). When this page and your own manual disagree, the manual wins.

What to know before you order

The MXU 700 changed drive belt in 2019, so the belt row lists two numbers with their years. It takes 2.4 L of SAE 5W-50 at an oil change, 2.6 L with the filter, and the same YTX20L-BS battery and CR7E plug as the rest of the large MXU and UXV range. The LE versions run larger 14 inch tires at 10 and 14 psi.

MXU 700 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 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
Front gear oil drain bolt 31 23
Rear gear oil drain bolt 20 14

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.

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.
