After a few years spent testing, in 1975 the definitive production of the 175 cc came into force.
The colour range mirrored the traditional one, that is the frame and the over structure were metal grey for all models, the tank was metal green for the 50 and 175cc, metal red for the 100cc, metal blue for the 125cc, metal red or Bordeaux red for the cross 50 and 125 cc.
This colour range is the one meant to be produced but as a matter of fact depending on the purchasing increasing demand pressure, on the deadlines and the hampers found in every manufacturing process, the bikes were made with all the stock components available in the warehouse, although they did not respect the initial design.
This season was so rich in successes that the new 1976 model, called Silver Vase, was made and produced just after the Six Days and was produced to honour the prestigious victory of the Team.
The new series, which faithfully copied the winning models and was first introduced at the Milan Motor Show in Milan, where the well-known six-gear models were joined by the new seven-gear Sachs engines, and also by the new competition 50 belonging to the Silver Vase series.
SWM has a great 1975, it won everywhere and reached an unrecorded commercial success.

Pierluigi Rottigni eventually targeted the Italian Championship winning the 125 class, while Pierluigi Laureati ranked second behind Gritti in the 175 class.
The European Championship was less lucky, Attilio Petrogalli ranked third in the 100 class and also Pierluigi Rottigni ranked 3rd in the 125 class.
Although the Valli Bergamasche (13^th/14^th September) did not belong to the European circuit, there were no doubts on the effective quality of the mechanical means, as SWM won three classes during this competition.
Pietro Gani won the 50 class, out of the 46 participants to this competition, 21 were SWM “machines”, in the other classes there were three 75cc, thirteen 100cc, seventeen 125cc and five 175cc.
Attiglio Petrogalli ranked 1^st in the 100 class, followed by Michele Cappellazzi, 3^rd. Also Pierluigi Rottigni won the 125 class, followed by Maurizio Radici, 4^th, while Luigi Petrogalli ranked 3^rd in the 175 class, followed by Gualtiero Brissoni 5^th.
Despite its well established tradition, the Valli Bergamasche was not included in the European Championship in 1975, the 5^th European competition was moved to Alano di Piave, on impassable mountains on the Grappa Massif, but also on that occasion SWM shone and Pierluigi Rottigni ranked first in the 125 class.
