The French department of industry had a
construction competition in 1978 which was won by three gentlemen by the names
of Louis Boccardo, Dominique Favario and Thierry Grange, hence BFG. The idea was
to put a car engine in a motorbike frame and was manageable enough to actually
make it into production. According to certain sources it was part of the company
that had been working with the manufacture of the Concorde that got the
assignment. According to the instruction book the responsibility was in the
hands of the moped- and bike manufacturer Motobécane, at least towards the end
when the BFG factory had financial trouble.
The name BFG comes from the initials of the
designers. Louis Boccardo, Dominique Favario and Thierry Grange. In the late
development of the BFG, Louis BOCCARDO was made redundant as he was developing
at the same time another motorbike, the MF
The company SOMA designed the gear box and the rear transmission with its
specific castings. The engine, originated from the GSA CITROËN car, was
re-fitted with new accessories, improving the look and the motorbike
functionalities : New tappets covers in moulded alloy, traditional ignition and
fuel pump were replaced by an electronic ignition and an electric fuel pump
dipped into the fuel tank made in rotomoulded plastic. The equipment of a BFG
are made for grand touring ; shaft driven, full fairing offering a good
protection to the pilot, « Jaeger » dashboard (coming from the RENAULT 5 Alpine
car) showing the neutral gear, the red zone, aso. The engine of the BFG
perfectly answers the grand touring use with its high torque available even at
low rpm.
The BFG was produced in La Ravoire, near Chambery, in the french Alps. About 400
units were manufactured from 1982 to the end of 1983. In 1984, MBK took over and
transfered the production to Saint Quentin in the North of France. Between 1984
and 1988, only 150 machines were produced. 1988 was the end of factory made
machines. In 1989, the spare parts stock was sold to « Atelier Précision » in
the North of France. Précision used to manufacture classic sidecars and
assembled a few couples of bikes. They stopped all activities in 1996. In 1996,
the stock of spare parts from Précision was bought by the BFG motoclub. The club
is now responsible for supplying all needed parts, but the production of new
bikes is definitively over.

Technical
The engine is a 1 299 cm3 GSA engine where the
modifications were kept to a minimum. Among other things the fuel pump has been
replaced with an electric one and the distributor has been replaced with an
electronic ignition system. The rocker covers are made of light alloy and the
exhaust system is of course replaced with chromed pipes and silencer. The clutch
is modified to make it manoeuverable by hand. The gear box is specially made, as
is the tubular frame. The gearbox has 5 gears with neutral between 1st and 2nd
gear, and integrated with the cardan. An odd detail is the use of straight gears
in the gearbox. The brakes and wheels are from Brembo, like the Moto Guzzi, and
the silencers are also Italian.
More car parts
On the electrical side there are more car parts. The headlamp is from a Renault
R16 and the instrumentation from an Renault 5 TS. The generator and starter
engine are from the GSA. Covers, tank and saddle are specially made. The tank
isn't placed in its ordinary place, where the air filter, battery and relays are
mounted, instead it's placed under the saddle (in the same way as the Honda Gold
wing). In the lower part of the covering there's the air intake, and the fan on
the motor has been retained which means there's ample cooling even when driving
slowly or standing still.
It's very long and wide, like a large BMW, but a few sizes bigger. The wheel
base is 20 cms longer on the BFG.
