278cc Liquid-Cooled Single-Cylinder SOHC 4-Valve Piaggio HPE (Steel Monocoque + Dry CVT) · Source: Piaggio Vespa GTS 300 HPE Official Use & Maintenance Manual
According to the Piaggio Vespa GTS 300 HPE Official Use & Maintenance Manual, the 2019–Present Vespa GTS 300 HPE / SuperTech (chassis ZAPMA36/ZAPMD31) requires 1.15 L (1.22 US qt) of SAE 5W-40 (JASO MA OR MB, API SN Synthetic) engine oil for a drain-only change and 1.3 L (1.37 US qt) with filter service (Piaggio 82635R / HF183). Standard solo cold tire pressure is 180 kPa / 1.80 bar / 26 PSI front (120/70-12 51P) and 200 kPa / 2.00 bar / 29 PSI rear (130/70-12 62P), paired with 1× NGK CR8EKB spark plug(s) and a YTX12-BS / YB10L-BP battery.
Drain only: 1.15 L (1.22 US qt)
R 200 kPa (2.00 bar)
Est. Range: ~247 km (153 mi)

4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
The 2019 HPE update (ZAPMA36) redesigned the cylinder head and piston over the older Quasar 300, followed by the 2023+ keyless chassis update (ZAPMD31). Both HPE series require strict 5W-40 full-synthetic oil checks.
Oil & Clutch Mechanical Engineering Note
Two crucial differences from Japanese scooters: Piaggio specifies 100% synthetic SAE 5W-40 (API SN / JASO MA), AND the Vespa GTS 300 oil dipstick MUST be screwed all the way in to measure the oil level accurately!
Garage Wrenching Gotchas
- HPE 300 engines can consume small amounts of oil during sustained highway runs; with only a 1.3 L sump, check the dipstick (fully screwed in, cold or 10 min after shutdown) every 1,000–1,500 km.
- Small 12-inch wheels spin faster and transmit sharper pothole impacts; inspect rear tire tread center wear closely around 6,000–8,000 km.
5. Frequently Asked Questions (FAQ)
Do you screw the dipstick in to check oil on a Vespa GTS 300 HPE?
Screw it all the way in! Unlike Honda/Yamaha scooters, Piaggio designs the GTS 300 dipstick to be read after threading the cap completely down on level ground.
What oil viscosity and capacity does the Vespa GTS 300 HPE require?
Use full-synthetic SAE 5W-40 oil; refill capacity with a new spin-on oil filter (82635R / HF183) is 1.30 L (1.37 US qt).
Where is the battery located on the Vespa GTS 300?
The 12V 10Ah battery sits inside the central floorboard tunnel compartment underneath the four-screw center cover.
