GPO 45 mm tuning cylinder suitable for various Puch mopeds (Puch Maxi S / N, Puch X30 Sport NS / NL, Puch X30 NG-2A, as well as Puch Supermaxi).
In order to get the full power out of the cylinder, a racing exhaust and a larger carburetor should be fitted.
The matching stud bolts for the intake and exhaust can be found in the accessories.

This racing kit is also offered in other stores under the names DMP, PSR, Power One or Akoa. However, it is actually just a good, inexpensive standard replacement part. GPO – GOOD PARTS ONLY.
