Airsal has once again put its hands on the 49er sports cylinder kit, and the result is this 68.4ccm (45mm) racing cylinder kit for Puch Maxi, X30 mopeds. The cooling fins are longer than on the original cylinder and lead to improved heat dissipation.

The racing kit includes all parts required for assembly, such as the gasket set, pistons, piston rings, etc.

Adjustment work on the crankcase is not necessary. The cylinder head is not included in the scope of delivery, the original head can simply be used.
