1965 - After the controversy of the previous year East Germany was diplomatically satisfied with the victory and left England the honor and the burden of organizing the International Six-Days Trial, which ran from the Isle of Man 20th to 25th September.
Under leaden rain-filled skies 299 riders competed in this difficult 40th edition, decimated by some disorganization and bad weather, so much so that only 82 crossed the finish line and only 19 obtained gold medals.
Eight teams of six riders each riding domestic motorcycles challenged each other to win the Trophy for Czechoslovakia, East Germany (GDR), West Germany (BRD), England, Soviet Union, Poland, Spain and Sweden.
Italy was absent for the second consecutive time, but this time for lack of the resources necessary to prepare the team and assist the drivers and mechanics involved in the race.
The only Italian was Arnaldo Farioli on a KTM.
There were however four French riders: Mouvet, Cavaille and Dion riding the brand new Morini 150 Regularity and Lecerf riding a Motobecane D52 Trial.
The Morini 150 Regularità models appeared markedly different from their debut at the 1964 Valli Bergamasche, with different ratios, a new camshaft that improved performance and a 21-inch front wheel with a trial tyre.
The first to retire was Lecerf, but even the best did not go beyond the third day.
All predictions at the start pointed to the formidable GDR squad and their unbeatable MZs that even beyond national borders reiterated their undisputed superiority, repeating the triumph of 1964.
Peter Uhlig, Hans Weber, Horst Lohr, Bernd Uhlmann, Werner Salewski and Karlheinz Wagner ensured a leading position in Eastern Germany Trophy, removed to 2nd place by Czechoslovakia, then the third with Sweden, England, 4th, 5th BDR, Poland 6th, 7th Soviet Union and finally the eighth position went to Spain.
The number of riders competing for the Silver Vase was larger , with 21 teams of four riders each, riding motorcycles domestically produced or foreign, representing Czechoslovakia, West Germany, East Germany, England, Netherlands, USSR, USA, Poland, Spain, Austria, Belgium, Finland, Ireland and Sweden, but the East Germans Günter Baumann, Klaus Teuchert, Golz and Horst Werner Stiegler on MZs prevailed over everyone.
In second place was West Germany BDR A team, followed by Czechoslovakia A in the third position, Sweden A fourth, 5th position want to the Czechoslovakian B team, East Germany DDR B 6th, England B in 7th and 8th to West Germany - BDR (B).

1966 – After the Isle of Man was over, the 41st edition of the Six-Days races moved to Sweden, Villingsberg, from 30th August to 4th September. The organization adopted a more accessible course, less selective, so much so that of the 287 starting riders 207crossed the finish line well. There were 149 gold medals awarded, 35 took the silver and 23 bronze.
In contention for the Trophy only 7 teams of six riders each, with nationally produced bikes, entered in three classes, but of these only three teams arrived at the end with all the crews to complete: DDR, England and the BDR.
18 good riders contended for the title, separated by only a few seconds in the special stages. Everyone except the West German Specht, delayed by temporary power problems on the fourth day, arrived with zero penalties.
The difference was again made by the modern German two strokes that kept them at the top of the world classifications.
The DDR team, all on MZ, made up of Peter Uhlig and Horst Lohr 175cc, Hans Weber MZ 250 and Werner Salewski - 250, Karlheinz Wagner and Klaus Teuchert - 350 won over the British Triumphs and BSA who finished second, while West Germany took third position.
This year the circus of competing Silver Vase teams was even more crowded than the previous one with 23 teams of four riders each at the start riding national or foreign produced machinery.
The relative easiness of the route allowed five teams to finish with zero penalties and the difference was again made during the special tests.
The BDR German four rider team took the plaudits - Norbert Gabler - Hercules 50, Klaus Kämper - Zündapp 75, Dieter Kramer - Zündapp 125 and Erwin Schmider - Zündapp 100 followed by their Eastern cousins ​​who ran well but had to settle for second place, followed by Finland B, Czechoslovakia B and England A.
Italy deserted the ISDT in 1966, mainly because of the lasting myopia of the principal manufacturers who did not understand the importance of the event as a real bridge capable of projecting the various industries onto the growing world market.
They concentrated on the modest domestic market that had seen them born and without a direct confrontation of ideas and new technologies they continued to produce outdated technology, snubbing the big events and the most formidable advertising media, the same who, in a few years, would heavily influence the destiny of all motorcycle factories.
The only two Italians personally present were the two riders from Bergamo - Arnaldo Farioli on a  KTM 50 and Franco Dall’Ara on his Morini 125, who took the gold medal.
Even in Sweden there were a decent handful of U.S. riders such as Bud Ekins, John Penton, Dave Ekins, Leroy Winters, Jack Krizman, Charlie "Hockie" Hochderffer, Malcolm Smith, and on this occasion their presence was linked to a curious anecdote.
The entire fleet sailed from America without a bike because they were to be met with a complete set in Sweden of Maico 350 and 500.
These expectations were disappointed however and in their desire to participate the Americans faced the emergency directly, addressing the motorcycle manufacturers engaged in the ISDT.
Thus the U.S. team competing for the Silver Vase, presented itself at the starting line mounted on highly capable motorcycles.
Bud Ekins and Jack Krizman received two sturdy Husqvarna 250s while Dave Ekins a Zündapp 125.
Hockie Hochderffer, to whom was entrusted the Official Hercules 125, competed with the number 269 and won the silver medal.
Together they were classified in 13th place.
