R 900 Bol d'Or – 1977

Failed promise

In the mid-Seventies, cycling experienced a renaissance in France. In 1975, Renault bought an interest in Motobécane, which led to the construction of a grand prix racer in 1977. Soon, Renault began selling Moto Guzzis and Benellis, two established Italian names, in France.

Specially-Built Six

To mark the occasion, a specially-built Benelli six with a French frame was entered in the Bol d'Or 24-hour race. The project was entrusted to Philippe Moc, who had previously set a number of sidecar records. But it was certainly no easy task, for the Italian six-cylinder engine was very wide and difficult to house in the frame of a racing bike.

Innovative Layout

Nevertheless, Moe succeeded brilliantly, with an innovative layout which was the direct inspiration for the Elf produced the following year by Andre de Cortanze. The most spectacular aspect of the Benelli-Moc was its streamlined styling in front of the steering head and its six-branch exhaust system in which six five-foot-long exhaust pipes were entwined around the engine. Two machines were prepared for the Bol d'Or but failed to grab any glory. Finished just two weeks ahead of the race, they suffered from a lack of development time. The Baloche/Espié machine failed to last beyond the fifth hour, and the Boulom/Montrémy bike covered only 536 miles in 24 hours. Benelli-Moc never raced again.
