Joey rode the famous Agrati Sales Ltd. Benelli 750 Sei six cylinder machine during the Isle of Man TT Formula 1 in 1978.

The machine was prepared by Agrati Sales Ltd., the English Benelli importer, who also was Joey’s entrant. Unfortunately Yer Maun was forced to retire in the second lap due to mechanical problems.

The Benelli 750 Sei (= Italian for “ six “) was the first ever six cylinder production motorcycle. The six cylinders each had a bore and stroke of 50 x 50.6mm, delivering a capacity of 747.7cc. The single overhead camshaft engine delivered a power output of 71 bhp at 8,500 r.p.m. The first prototype was shown as early as 1972.




Apologies to the original source of this information, however I found this in my historical database on the TT
