Photo of Rolling chassis and engine of an Italian Mazzilli Motorcycle ISDT 1973

We only have this one Mazzilli picture, believed to be of a probably Italian produced Sachs powered Ceriani teleforked & rather nicely constructed machine of the 1970 to 1976 era, CAN ANYONE OUT THERE PLEASE HELP US WITH INFORMATION, riders types events & images.

Thanks to Italian STT reader Massimo who provides this link to a site dedicated to creating a register of the bikes.

Thanks to Arthur Williams one of our greatest authorities on the ISDT for pointing out that #262 is Dai Jeremiah who went on to be a firm fixture in the British ISDT Trophy team

#292 Dave Hobbs pinned in a group of Swedish riders no doubt on lightweight powerful Husqvarnas, Monarchs or similar whilst the institutional British teams of the Forces and Police were expected to lug around traditional British Heavy Metal in order to fly the flag.

Arthur Williams provided some bits so we start a 1973 page Britain’s Best performance for 7 yrs to 2nd in the Trophy Event. 1100 miles to go, 71 Checks, 11 Special Tests.   48th ISDT 17 to 24 inc September at Berkshire Hills, Massachusets USA for the first time outside Europe.
26 Local Conservationists contested the right to proceed with the even & tried to obtain a court injunction, only by a Technicality did the event get underway at 7am on Monday.   Czechs again romped away with it overall, whilst 750cc BMWs weighing 300 lbs proved more of a handfull than expected.   10 Trophy teams were in the melting pot at the end of the first Day.   Army Vase B team was fine, Army Vase A team had lost T Walker with surprisingly a vibrating Sachs power plant.   Arthur Browning had a series of Punctures causing a 4 minute Penalty.

The Penton USA Team poses for a photo.
Back row: Jim Hollander, Paul Danik, Carl Cranke, Billy Uhl, Doug Wilford, Joe Barker. Front row: Dane Leimbach, Tom Penton, John Penton – Manager, Jeff Penton, Jack Penton.
Jim was the top scoring Privateer during the qualifiers in the USA in ’73 with 5 Gold Medals, and was placed on the 4-man Vase B Team. Riding a 125cc, Jim was the only Penton rider not to finish that year, ending up in the hospital following a crash in the woods. Penton’s disappointment that year was compounded by Jeff Penton dropping to a Bronze w/ silicone sealant clogging the carb.

Here is another of 258 looking well received everywhere.  Helmut Clasen again to rescue us identifying Ron Keyes with the Canadian Managers, thanks .

Interesting side note: In the official program of the 1973 ISDT, Bultaco observed trials champion Lane Leavitt is listed on the Vase “B” team. Lane declined to ride the ISDT after Bultaco would not outfit him with a prototype Frontera (as used by some of the Spanish factory riders) and instead wanted to mount him aboard a Matador. Lane argued that the Matador would not finish the six days of riding. He was also contesting the observed trials championship in 1973 and after declining the Vase ride, went on to capture the trials championship astride a Sherpa T. Jim Hollander was drafted to fill Leavitt’s spot on the Vase B team.
