1930 – In 1930 the Six-Days returned to France, in Grenoble.
A novelty was represented by Italy, which, after its timid debut the year before participated for the first time, with three official teams, one fighting for the Trophy and the other two in the Silver Vase, taking an astonishing result.
The Gilera team competing for the Trophy presented Luigi "Luisin" on a Gilera at the starting ribbon, the brother of the patron Guiseppe, with sidecar, and passenger and then Gino Zanchetta Rosolino Grana Miro and Maffeis, who turned out to be winners of the event .
Regarding the sidecar, remember that the "passenger" did not simply play a passive role but was an integral part of the crew.
He had delegated important functions and was a great support for the final result.
At a minimum he should be a good mechanic, but he was also able to support the rider on the roughest terrain, helping in every way.
Gino Zanchetta, for example was an Air Force officer and also an excellent rider with a deep knowledge of mechanics.
The Silver Vase was won by the hosts, the French A. Sourdot, R. Debaissieux and N. Coulon, immediately followed by another team of Italians, the MAS, which stands for Motorcycle Alberico Seiling, a Milanese engineer who designed and produced these great motorcycles from 1922 to 1960.
The MAS team, composed of Silvestri, Bonatti and Boneschi did well in placing second in the championship, crowned by Silvestri, and also won the first Italian gold medal.
The Sporting Group Ardea, composed of Vailati, Fieschi and Martelli, suffered a disaster however.
Vailati and Fieschi were disqualified on day 5 for irregular gasoline filling, while Hammer was forced to retire due to mechanical failure.

1931 - After the surprising victory of the Gilera, Italy also obtained the right to host the International Six-Days, which started from Merano, August 30, 1931.
At the start 88 competitors showed up, including 31 Italians, 18 British, 7 Dutch, 6 Germans, 2 Czechs, 2 French, 1 Hungarian, divided into two categories, up to 250cc and over 250cc.
The Gilera team, still composed of Luigi Gilera, with sidecar, with a new passenger Meani, Rosolino Grana Miro and Maffeis, was confirmed at the top of the standings and won for the second consecutive time the Trophy. Behind it they placed Germany, England and France.
The Silver Vase was awarded to the Dutch DH Eysink, G. Bakker-Schut and A.P. van Hammersveld.

1932 – The 30's proved to be an interim period, altogether lacking in novelty, except in the technological field in which progress was made ​​even faster.
Scrolling down the charts we see the usual superiority of the British, threatened by the new emerging power of Germany, whose crews are becoming more efficient and competitive, reflecting what was already happening on the economic and military fronts.
In 1932, the ISDT was again started from Merano, but this time the British swept the board winning both the cups which were up for grabs after a head to head with the Italians which ended only on the last day of the test.
Italy and England were, in fact, the only two countries that arrived at the finish of the sixth day penalty with zero penalties and perfectly equal.
Albert E. Perrigo, G.E. Rowley and N.P.O. Bradley took care of winning the Trophy – they popped up at the last minute in the final speed test, a specialty where the English bikes showed a clear superiority, while the Silver Vase was won by another trio of English, GW Walker, Jack Williams, R. Mc Gregor.

1933 – The Six-Days returned to England, to Llandrindod Wells in Wales but this time it was the BMWs that showed themselves invincible.
The Germans Ernst Henne, Josef Stelzer and Josef Mauermayer, with sidecar and passenger Ludwig Kraus, conquered the Trophy while the three British riders V.N. Brittain, Jack Williams and G.F. Povey, took the silver vase consolation prize.
There were only two Italian riders classified: Boneschi in the gold medal and Picozzi, on MAS, for the silver medal.
