Model-Year & Chassis Generation Notes
Celebrating Vespa’s 1951 Varese International Six Days gold medals, Edition I (2018) used the 21.2 hp Quasar engine while Edition II (2019–2022) upgraded to the 23.8 hp HPE motor.
Oil & Clutch Mechanical Engineering Note
With higher cam lift and combustion pressure in Sei Giorni II’s HPE top end, pair full-synthetic ACEA A3 SAE 5W-40 oil with genuine Piaggio spin-on filter 82635R.
Garage Wrenching Gotchas
- Pull and rinse the cylindrical plastic mesh pre-filter behind the sump drain plug at every change, inspect its O-ring, and torque the plug to 24 N·m.
- Factory matte Verde/Grigio Sei Giorni paint permanently burnishes if rubbed with abrasive polish—clean strictly with matte-safe pH-neutral wash.
5. Frequently Asked Questions (FAQ)
What are the engine oil and rear hub gear oil capacities for the Vespa Sei Giorni 300 HPE (Edition I / II) scooter?
With an isolated dry CVT belt case, the engine requires 1.15 L drain-only or 1.3 L (1.37 US qt) with filter/screen (Piaggio 82635R / HF183) of SAE 5W-40 (JASO MA2). Service the rear reduction hub separately (final drive 250 ml).
How do you accurately check the oil level on the Sei Giorni 300 HPE (Edition I / II), and what are its service intervals?
After warming the engine and waiting per manual procedure, thread the dipstick all the way in before removing it to read the oil level (resting it unscrewed causes overfilling). Torque the drain plug to 24 N·m with a new crush washer. Factory oil change intervals are every 10,000 km, with valve clearance inspection every 20,000 km.
What are the cold tire pressures, puncture repair type, seat height, and range of the Sei Giorni 300 HPE (Edition I / II)?
Fitted with 120/70-12 51P front and 130/70-12 62P rear tubeless rims (compatible with roadside plug kits), set cold tire pressures to 26 / 29 PSI (180/200 kPa) solo or 29 / 36 PSI loaded. Seat height is 790 mm (31.1 in) at 160 kg wet weight, delivering ~255 km per 8.5 L tank.
