Piaggio 834751 Flywheel Fan Cover / Volute Cover – Ape 50, Ape Mix and Ape 50 E4 (1998-2023)

The Piaggio 834751 snail cover is the original flywheel fan shroud for the Ape 50 2T: the black plastic cap that seals the forced-air cooling snail housing and channels fan air onto the cylinder. The official Piaggio spare parts catalog lists it for the Ape Mix 50 2T (1998-2008), Ape 50 2T (2009-2018), and Ape 50 2T E4 (2018-2023). Product code 834751.

✓ Strengths

• Original Piaggio spare part – this is the part number specified in the official parts catalog, not an aftermarket equivalent.
• Direct mounting – molded for the original housing: it attaches to the standard points without needing adaptations or drilling.
• Already black – it comes in the factory standard color and requires no painting.
• Covers twenty-five years of Ape 50 – the same code applies from the 1998 Mix through to the 2023 Euro 4 model.
• Engine protection part – without the intact snail housing, air does not reach the cylinder, causing the 2-stroke engine to overheat.

Technical specifications

Vehicle compatibility

This list is taken from the official Piaggio spare parts catalog (B2B area). If you have any doubts, send us your Ape's chassis number and we will verify the correct code.

Perfect for

This is the spare part for those who keep an Ape 50 working: street vendors, nurserymen, workshops, and those who use it daily in historical centers. The snail housing is plastic and attached to the engine, so it is the first part to crack due to vibrations, heat, and occasional bumps during maneuvers. Replacing it costs little and restores the cooling system, which is everything on a forced-air 2-stroke engine.

Frequently asked questions

On which Ape models can the Piaggio 834751 snail cover be mounted?
It fits the Ape 50 2T in all three generations provided by the catalog: Ape Mix 50 2T from 1998 to 2008, Ape 50 2T from 2009 to 2018, and Ape 50 2T E4 from 2018 to 2023. It is the same code for all three: the engine type changes, but the snail housing does not.

What is the purpose of the snail housing on the Ape 50?
The Ape 50 has a two-stroke engine with forced-air cooling: the fan integrated with the flywheel pushes air into the snail housing, which channels it toward the cylinder fins. The cover seals the housing: if it is missing or broken, air is dispersed and the cylinder runs hotter than intended.

Where is it located on the vehicle?
It is located in the engine group, above the magneto flywheel: it is the round black plastic cap that is visible as soon as the engine compartment is opened. It is removed by unscrewing the perimeter screws, without needing to open the crankcase or remove the cylinder.

What does the package contain?
It contains only the snail cover, as seen in the photo. Screws, gaskets, and the flywheel fan are not included: if your screws are rusted or stripped, it is advisable to obtain them separately before reassembling.

Is it an original Piaggio or an equivalent?
It is the spare part with the Piaggio factory code 834751, original equipment. It is not an aftermarket copy: the mold, fixing points, and geometry of the housing are those provided by the manufacturer, so it mounts directly to the original seat.

How can I be sure it is the right one for my Ape?
Check the year and version in the compatibility table: if your Ape does not appear or you have a specific setup, write to us with your chassis number. We will check the code in the official Piaggio parts catalog and confirm if this cover is intended for your vehicle.
