AIRSAL Cylinder Kit - Ø39.9mm
Manufacturer reference: 010814399

This AIRSAL Ø39.9 mm cylinder kit is aimed at riders looking for a robust part for the restoration or preparation of an urban 50cc engine. Designed to fit the engine frames of scooters and small displacement city bikes, it provides the necessary mechanical foundation to restore the top end and achieve clean cylinder operation.

The kit is suitable for both workshop interventions and experienced DIYers: checking the bore, inspecting the piston and rings, and paying attention to the gasket surfaces and sealing are essential for a reliable installation.

Compatibility (model examples)

• GILERA SMT 50 (2019 - 50 cc)
• APRILIA RS4 50 (2016 - 50 cc)
• DERBI SENDA 50 SM DRD X-TREM (2015 - 50 cc)

Before installation, check the exact compatibility with your engine (bore, piston pin, gasket height) and plan for associated wear parts (rings, gaskets, circlips) if they are not included. For optimal results, have the installation done by a professional or carefully follow the manufacturer's recommendations.
