Airsal Racing 70cc Puch Maxi cylinder kit
The Puch Maxi remains a popular platform for tuning projects, and Airsal offers the right setup for those aiming to increase displacement: the Airsal Racing 70cc (Ø45 mm) cylinder kit with short cooling fins.
With this 70cc aluminum cylinder, Airsal delivers a true race cylinder for the Puch Maxi, offering even more power than the already strong 65cc version. As always: there’s no replacement for displacement. The cylinder also features additional transfer ports, which are supplied via special holes in the piston.
As usual, we recommend rejetting the carburetor or ideally upgrading to a larger one. A performance exhaust is also strongly advised to fully unlock the potential of this kit.
Supplied with 1-ring piston, small parts and gaskets but without cylinder head. The original cylinder head can be reused.
Attention: There are two versions of the cylinder for Puch Maxi engines, with short and long cooling fins. Fitment is identical, but for tuning projects we recommend the long-fin version for improved cooling.

Tuning Level: Racing
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
Aluminium cylinders
Aluminium cylinders are more powerful than cast iron cylinders, but require more regular maintenance and must be combined with different components such as a reinforced crankshaft and a larger carburetor.
How to run in an aluminium cylinder?
