Cylinder Kit Airsal Sport 65 Puch Maxi

cylinder with head Airsal Alu 65cc Puch Maxi

The Puch Maxi is still a popular choice for tuning projects, and Airsal delivers the ideal kit for those looking to boost displacement: the Airsal Sport 65cc (Ø44 mm) cylinder kit (with cylinder head) with short cooling fins.

With 65cc of displacement, this kit provides noticeably more power, strong torque, and a clear increase in top speed. Compared to cast iron kits, the aluminum cylinder offers better heat dissipation — a real advantage given the performance gain.

As always, we recommend rejetting the carburetor or, even better, upgrading to a larger one. A performance exhaust is also strongly recommended to get the most out of this setup.

Comes with a 2-ring piston, small parts, and gaskets, but without a cylinder head. The original head can still be used.

Note: Puch Maxi engines use two cylinder versions — one with short, one with long cooling fins. Both are identical in fitment, but for tuning purposes we recommend the long-fin version for better cooling.
