KYMCO X-Town 300i Service Specs: Part Numbers and Intervals

Michal B., KYMCO parts specialist

This is the service sheet for the KYMCO X-Town 300i (4-stroke single, liquid cooled, 275.6 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 (2018-2023) and the diagram the part is drawn on. The figures are KYMCO service data from the KYMCO X-Town 250i / 300i ABS service manual (2016-2018). When this page and your own manual disagree, the manual wins.

What to know before you order

The X-Town 300i takes a DPR6EA-9 plug, gapped 0.8 to 0.9 mm, where the smaller scooters use the CR types. It is liquid cooled, with coolant and brake fluid on a 10,000 km or yearly change, the air filter is a 3,000 km item, and KYMCO specifies SAE 5W-50 for the engine. The weight roller set changed for 2020, so check the year on that row.

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.

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.
