1980 – The commercial success of the last TF1 release run smoothly, it was orange, white and black. At the same time the new plants started being built, they were bigger than the previous ones and could host all SWM’s activities which otherwise were located in five different places.
As to competitions, SWM focused its efforts on the 125 class and superiors, leaving out the smallest classes which were bound to be gathered in the 80 class in 1981.
The bikes used by the official bikers were improved further.
Instead of the Corte and Cosso shock absorbers, both the new Compact models and the AG4 Marzocchi models with magnesium rafts were tested.
During the season the bikes became completely orange as the new tanks were made of Reticular Polyethylene MD (Medium Density) and the mudguards were made of Polyethylene in vacuum forming plates, even those of Medium Density, but linear and thus recyclable.
This new material was very though but it could not be varnished. Its particular molecular / reticular structure allowed fuel to pass through but this would ruin every kind of varnish of sticker.

The Italian Championship ended with two glorious results: Gualtiero Brissoni won both the 125 class and the absolute one, followed by Andreini 3rd and Marinoni 4th.
Marinoni too ranked second in the 250 and Andreini tanked 2^nd in the 500.
The results on European level were even better, thanks to the victory of three classes.
Gualtiero Brissoni confirmed himself as Champion of the 125 class, Marinoni won the 250 class and Andreini conquered the 500 class.
During the French Six Days in Brioude (22^nd-27^th September), Italy repeated the success of the previous year, once more thanks to a mixed team: Marinoni 250, Brissoni 350, Andreini 500 riding SWMs while Andrioletti 250, Taiocchi 350 and Croci 500 riding KTMs.
Guglielmo Andreini won also the 500 class.
