4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Despite the 360 badge, DT X360 shares the proven 320.6cc G5-SC single with adventure beak styling, wider handlebars, lighter alloy wheels, keyless ignition, and dual-purpose tires.
Oil & Clutch Mechanical Engineering Note
Gravel road climbs elevate crankcase and CVT temperatures—change full-synthetic SAE 10W-40 JASO MB oil (1.5 L) and paper filter HF566 promptly every 5,000 km.
Garage Wrenching Gotchas
- Toggle TCS off via the handlebar button before tackling loose gravel climbs, otherwise wheelspin intervention cuts engine power mid-incline.
- Dusty fire roads clog both the intake air filter and CVT cooling duct foam rapidly—inspect and blow out both filters after off-pavement touring.
5. Frequently Asked Questions (FAQ)
What are the engine oil and rear hub gear oil capacities for the KYMCO DT X360 (320 / 350) scooter?
With an isolated dry CVT belt case, the engine requires 1.3 L drain-only or 1.5 L (1.59 US qt) with filter/screen (1541A-LEA7-E00 / HF566) of SAE 10W-40 (JASO MB). Service the rear reduction hub separately (final drive 230 ml).
How do you accurately check the oil level on the DT X360 (320 / 350), and what are its service intervals?
Hold the bike upright on level ground 2–3 minutes after shutdown, wipe the dipstick, and rest it on the filler threads without screwing it in (threading it in reads artificially high and risks oil starvation). Torque the drain plug to 25 N·m with a new crush washer. Factory oil change intervals are every 5,000 km, with valve clearance inspection every 15,000 km.
What are the cold tire pressures, puncture repair type, seat height, and range of the DT X360 (320 / 350)?
Fitted with 120/80-14 58S front and 150/70-13 64S rear tubeless rims (compatible with roadside plug kits), set cold tire pressures to 29 / 33 PSI (200/225 kPa) solo or 29 / 36 PSI loaded. Seat height is 800 mm (31.5 in) at 194 kg wet weight, delivering ~325 km per 12.5 L tank.
