Piaggio 875111 Engine Half Crankcase Gasket 125-300 – Beverly, Vespa GTS, Liberty, MP3

The Piaggio 875111 crankcase gasket is the original gasket that seals the two crankcase halves of Piaggio Group's four-stroke engines, in the displacement range of 125 to 300 cc. It's a part only seen when the engine is open, but it's what keeps the oil in and the air out: if it fails, you'll see oil leaks along the crankcase mating line, unexplained drops in oil level, and in the worst cases, a loss of sealing with consequences for the entire engine. This gasket is never reused: every time the crankcase halves are separated — for crankshaft overhaul, bearings, gearbox, or oil pump — it must be replaced with a new one. The 875111 code is specified by the manufacturer for a huge portion of their range: Beverly, Liberty, Fly, Carnaby, MP3, X7, X8, X9, X10, X Evo, Typhoon 125, Gilera Nexus and Runner 4T, Aprilia Atlantic, Sport City and SR MAX, Scarabeo with Piaggio engine, and practically all modern Vespa 125-300 models, from LX to GTS up to 946.

✓ Strengths

• Original Piaggio spare part — factory code 875111, official designation "CRANKCASE GASKET"

• Extensive coverage — a single code for Piaggio, Vespa, Aprilia, Gilera, and Scarabeo from 125 to 300 cc
• The right part for a proper overhaul — always replaced, never salvaged
• Avoids the worse-than-the-cure remedy — no sealant spread instead of the gasket, which ends up clogging oil passages
• Low-cost spare part within an expensive job — saving here means redoing the entire assembly

Recommended products

If you're opening the engine, this gasket never travels alone: budget for crankshaft oil seals, main bearings, cylinder head gasket, and the transmission cover gasket. In our catalog, you'll find original Piaggio spare parts for a complete overhaul, including the 872909 crankcase gasket for those working on 400 and 500 engines.

Who it's perfect for

• Workshops and mechanics who overhaul Piaggio 125-300 engines and want the original part, not an equivalent with uncertain sealing
• Anyone with an oil leak on the crankcase line who needs to open the engine to fix it
• Anyone rebuilding the crankshaft, bearings, or oil pump and preparing a list of parts that must be replaced
• Anyone restoring or putting a scooter back on the road after years of being stationary and wanting to start with a new engine seal

Frequently asked questions

What is the Piaggio 875111 crankcase gasket?
It is the original gasket that seals the union between the two crankcase halves of the engine, called "crankcase gasket" in the Piaggio catalog. It prevents oil from leaking from the mating line and maintains the base seal. It covers Piaggio Group four-stroke engines from 125 to 300 cc.

When should it be replaced?
Every time the crankcase halves are separated: crankshaft overhaul, replacement of main bearings, work on the gearbox or oil pump. It should also be changed even if it appears intact when opened, because it has already settled and no longer guarantees the original seal.

What is the difference with code 872909?
These are two different crankcase gaskets for different engine families. The 875111 is for the 125-300 cc range, while the 872909 equips larger engines mounted on Beverly, MP3, X9, X10, Nexus, and Fuoco 400 and 500 models. Always check the code in your frame's catalog.

Can I use sealant instead of the gasket?
No, and it's a costly mistake. Sealant does not replicate the designed thickness of the gasket, and excess sealant can break off inside and clog oil passages. The original gasket guarantees the thickness, shape, and material specified by the manufacturer.

Which scooters does it fit?
The official Piaggio catalog lists it for Beverly, Carnaby, Fly, Liberty, Typhoon 125, MP3, X7, X8, X9, X10 and X Evo, Gilera Nexus, Runner 4T and Oregon quads, Aprilia Atlantic, Sport City and SR, Scarabeo with Piaggio engine, and all modern Vespa 125-300 models, from LX to GTS up to 946.
