High performance aluminium cylinder kit from Airsal with 50ccm displacement and hard coated cylinder track. Aluminium cylinders dissipate heat much better than cast iron cylinders. This makes the cylinders less susceptible to piston jamming or other temperature-related damage. The Airsal sport cylinder is already very powerful and offers a good torque curve. During assembly the carburettor must be retuned or better replaced with a larger sports carburettor.

All the parts required for assembly are supplied as shown in the illustration.

Attention: A mounting on mopeds with Euro4 engine (from year of manufacture 2018) is only possible in connection with the thread adapter 38293, because a temperature sensor (4-pole) with M12x1,5mm thread is installed on these models.
