INteresting, i just found out about this french MOtorcycle thanks to your video. Now im doing reaserch all over the net. SInce there were so few of this made,for how much are they sold ?
~650 BFG was built, you can read more here (in french) : www.bfg.asso.fr/ Engine was a Citroën GS engine, 1300cc 70hp, top speed 190km/h, 267kg, 22 liter fuel tank
Not a surprise, that the only costumer was the french police. It is not a pretty bike to look at, and it seems to be too long. It cannot be very smooth to drive in the city. But indeed a very rare bike.
none BFG was buy from the police or the gendarmerie: they did only made some tests on the BFG...only 650BFG was built, i have one (modified without fairing and custom look), was expansive, not a beauty but very pleasant to drive : the engine was realy a good choice and sound very nice
