45 mm racing cylinder from Airsal for your Puch moped / moped.
Fits Puch Maxi, X30 Sport NS/NL, X30 Sport NG-2A and Supermaxi.
The tuning cylinder with original piston fins delivers good performance at a low price.
Since the piston only has one piston ring, there is less friction. The cylinder is therefore designed for maximum speed, but in return delivers slightly less torque than the 44 mm version.
