Airsal 63cc Cylinder Kit 42mm – SYM / Peugeot 50cc 4T (XS1P37QMA)

The Airsal 63cc cylinder kit is designed for SYM and Peugeot 50cc 4-stroke scooters equipped with the XS1P37QMA engine (original bore 37mm, stroke 46mm).

With a 42 mm bore, displacement increases to 63cc, resulting in a significant torque gain and slight power increase compared to the original 50cc cylinder. Perfect for riders looking for better acceleration without major engine modifications.

The cylinder is made from aluminium for improved heat dissipation and can be installed directly on the original crankshaft. It is compatible with the original cylinder head.
