Engine Fluids, Gear Oil & Filter Specifications
| Engine Oil Viscosity & Standard | SAE 5W-50 / 10W-40 Synthetic API SL/SM JASO MB |
|---|---|
| Engine Oil Capacity | 1.3 L (without filter) / 1.5 L (with filter) |
| Final Drive / Gearbox Oil | SAE 80W-90 GL-5 — 230 ml (refill) / 250 ml (total) |
| OEM Oil Filter Part Number | 15400-LBA2-E00 (Paper filter cartridge) |

Field note: The Xciting 400i uses 1.3L for drain refills and 1.5L when changing the 15400-LBA2-E00 paper filter element. Final drive gear oil capacity is 230ml refill (250ml total).
CVT Transmission System
| Component | CVT Drive Belt |
|---|---|
| OEM Part Number | 23100-LKF5-E00 |
| Dimensions | 988 x 27.2 mm |
| Torque Spec | Drive face nut: 95 Nm |
| Cross-Compatibility | None |
Field note: At 95 Nm, this is the highest-torque variator nut in Kymco's lineup.
Engine Internals: Cylinder Head & Crankshaft
| Part No. | Qty | Part Name | Notes |
|---|---|---|---|
| 12200-LKF5-E00 | 1 | Head Comp., Cylinder | Resurface flatness tolerance 0.05mm max |
| 12210-LKF5-E00 | 1 | Valve, Exhaust | Check margin thickness > 0.5mm before reuse |
| 12220-LKF5-E00 | 1 | Valve, Inlet | Larger head diameter — do not swap positions |
| 12251-LKF5-E00 | 1 | Gasket, Head Cyl. | Single-use metal composite; never reuse |
| 14100-LKF5-E00 | 1 | Camshaft Comp. | Chain-driven; inspect lobe wear before reinstall |
| Part No. | Qty | Part Name | Notes |
|---|---|---|---|
| 13300-LKF5-E00 | 1 | Crankshaft Comp. | Heaviest-duty crank in the Kymco small-single range; check runout < 0.03mm |
| 13210-LKF5-E00 | 1 | Connecting Rod | Big-end side clearance spec: 0.1-0.4mm |
| 13010-LKF5-E00 | 1 | Piston (Std.) | Domed piston, 3-ring set |
| 13111-LKF5-E00 | 1 | Piston Pin | Lightly oil before install; hand-pressure fit only |
| 13115-LKF5-E00 | 2 | Piston Pin Clip (Circlip) | Directional installation — see expert note below |
Field note: At 400cc, this is the largest single-cylinder engine in Kymco's small-bore family, and piston
inertial loading on the pin clips is correspondingly higher. The gap must face 90° to piston travel,
never fore-or-aft — a backward clip compresses under load until it ejects into the crankcase, and
the freed pin gouges the cylinder wall on the next stroke, destroying the bore. Use only new clips and
confirm full seating by feel before closing the case.
OEM Body Panels & Color Matching
| Part Name | Pearl White | Matte Titanium | Deep Blue |

| Rear Trunk Cover | Consult Service Manual | Consult Service Manual | Consult Service Manual |
Field note: The Xciting 400i's large fairing panels have substantial surface area exposed to UV, and the
mounting tabs behind that painted surface become brittle around the same three-year mark seen across
Kymco's lineup. Never use an impact driver on body screws, and apply silicone grease to rubber grommets
before removal so large panels flex free without snapping a tab.
