1975 – The manufacturer continues with its policy of disengagement despite the many wins and successes by the Italian riders. 1975 is the turning point. Puch decides to race officially for the last time and to progressively disassemble the production of motorcycles and to concentrate its indirect assistance only to the smaller 50cc and 75cc models. The process starts whereby a handover takes place between Graz and Trevigliano. Activities start moving from Austria to Italy, with certain unavoidable consequences.
The Puch 50 cc was being set up in Italy, with the direct commitment of the Frigerio brothers, whose badges appeared alongside the Austrian manufacturers, giving rise to the model series Puch-Frigerio.
The Austrian manufacturer only supplied the engines, which with an aluminum cylinder head (40mm x 39mm) at a noticeable 45˚ slant dictated the sharp lines of the cradle.
The fist model produced for commercial purposes, a 50cc, thanks to a chrome barrel and four generous transfer chambers, managed the considerable amount of power of 9,7 hp at 10.000 rpm; with a 24mm Bing carburetor, an efficient electronic starter and a sturdy six speed gearbox.

The frame reminded one of its older siblings, with a tubular upper spar and bolted double cradle, it remained competitive for many years.
All the body parts were the best available, Marzocchi forks and shocks, long 30mm travels with aluminum sleeves, conical Grimeca hubs and alloy metal rims: the mudguards were mounted high and made of a plastic material as was the fuel tank.
For the sports model Puch delivered specially designed engines to the Frigerio brothers, painstakingly rounded off with great care taken with each detail.
The official motorcycles, both 50cc and 75cc, were fitted with a magnesium engine cover and Mahle pistons with a single ring. Each was fitted with the best available body parts, starting with the Marzocchi forks with magnesium sleeves in the front, the newly developed Marzocchi gas shocks in the rear; the 75cc reached a dazzling power output of 17,5 hp at 10.000 rpm.
On the production motorcycles, a small cover was fitted under the engine to protect the silencer from blows and the cylinder from mud splashes.
