MXT Cylinder Standard 50 ccm AC 4-Square complete with piston and gasket set for Piaggio AC

This 4-Square grey cast iron cylinder from MXT is designed in original equipment manufacturer specification for air-cooled Piaggio engines with 50 ccm. It is dimensionally identical to the original cylinder and is approved for operation on public roads. Piston, piston ring, piston pin, piston clips, and gasket set are included in the scope of delivery - the cylinder head is not included and must be procured separately.

Important note for Piaggio ZIP 25 BASE/SSL:

• The scavenge ports of this cylinder are not narrowed, unlike the stock cylinder. The cylinder fits the SSL25 housing, but may lead to a performance increase that requires an adjusted carburetor setting.

Product features:

• Grey cast iron cylinder 50 ccm, air-cooled (AC), 4-Square
• Dimensionally identical to the original cylinder - direct replacement without adjustments
• Approved for operation on public roads
• Piston made of aluminum (CNC-machined), black coated
• Scope of delivery complete with piston, piston ring, piston clips, piston pin, and gasket set
• Cylinder head not included in the scope of delivery - available separately

The grey cast iron cylinder with cooling fins is designed as a spare part according to the original dimensions of the Piaggio AC engine. Since the scavenge ports are not narrowed, deviations in performance behavior compared to restricted stock conditions may occur - especially for 25 km/h versions, the carburetor setting must be checked after installation.

• Version Standard, original equipment manufacturer specification, 4-Square, air-cooled
• Engine type Piaggio AC (air-cooled, 2-stroke)
• Displacement 50 ccm

Vehicle and model compatibility:

Compatibility includes models such as Piaggio Zip, Typhoon, NRG, Liberty, Fly, Vespa ET2, LX, Primavera, Sprint, Aprilia Scarabeo and Sportcity, Gilera Stalker and Typhoon, as well as Derbi GP1 and others. For Piaggio ZIP 25 BASE/SSL, please note that the cylinder is not restricted and a carburetor adjustment may be necessary after installation. The prerequisite is always the air-cooled Piaggio 2-stroke engine with a square cylinder base dimension.

Assembly and application notes:

• The cylinder is replaced directly against the stock cylinder. All gaskets required for installation are included in the scope of delivery. The cylinder head must be procured separately and checked for flatness before installation.
• Important note: For Piaggio ZIP 25 BASE/SSL models, check and adjust the carburetor setting if necessary after installation.
• Observe tightening torques according to manufacturer specifications.

Note on checking before purchase:

• Before purchase, check the engine type (Piaggio AC, 2-stroke, air-cooled), vehicle model, and for ZIP 25 variants, the vehicle version (BASE or SSL).
