• The TZ750 in its final 'F' version
• Formerly raced by Team Yamaha IMN (Inter Motor Nederland)
• 'As last raced' condition
• Offered for restoration

Although Formula 750 had been intended as a class for modified production roadsters, Yamaha managed to get its TZ750 racer homologated provided that at least 200 were built. The pre-production prototype was tested in Japan towards the end of the 1973 by Australian World Champion Kel Carruthers, who on his retirement at the season's end assumed the role of managing Yamaha's works team in the USA. Works riders Gene Romero and Kenny Roberts tested the first production examples prior to the season-opening Daytona 200, but the honour of securing the TZ750's debut race win at the Florida track went to Giacomo Agostini, newly arrived from MV Agusta.

Despite the 'TZ750' moniker, displacement remained at 700cc until October 1974 when the second batch of TZ750Bs was released featuring a full-size (750cc) engine, For 1976, the works TZ750s used the YZR500 Grand Prix racer's lightweight mono-shock frame and a more powerful engine ported to Carruthers' specifications. Designated 'OW31' by the factory, these works bikes provided the blueprint for the customer TZ750D for 1977, although the production models did not fully match the works specification and were only marginally lighter than the twin-shock TZ750C. In its ultimate, OW31-type configuration, the TZ750 continued essentially unchanged until production of the final 'F' variant ceased in 1979.

Like the smaller TZ twins, the TZ750 was an enormous success, providing privateers the world over with the means to compete against the factory teams in Formula 750. Packed grids of near-identical bikes made for close racing, and no-one who witnessed these demanding machines being wrestled around UK short circuits, the Isle of Man TT course or Daytona's bumpy banking will ever forget the sight. Various authorities have suggested a manufacturing total for the TZ750 at somewhere in the 500-600 range, though more recent research suggests that Yamaha eventually made a little under 800. Today these spectacular machines are highly sought after by collectors and classic racers alike.

Formerly raced by Team Yamaha IMN (Inter Motor Nederland, the former Yamaha distributor in Holland), this late example is understood to incorporate a replacement frame with indistinct hand-stamped number: either '409-200373' or '409-200375' (TZ750F production began at '40-200197'. There is no engine number, the crankcase too appearing to be a replacement. We are advised that the engine is complete, including the gearbox, clutch, generator, and CDI unit, though it has been stored without protection caps on the carburettors. A wonderful opportunity to acquire one of the most charismatic racing motorcycles of modern times, ripe for sympathetic restoration.
