In 1976, a Swiss team entered a GL1000 in the World Endurance Championship.
The first race was the 24 hours de Liège, where the machine ridden by Fourgeous and Burki finished an astonishing 5th!
The frame was "not standard" and had been built by Pierre Doncque, who had built the frame for the Kawa Godier-Genoud that won the Bol d'Or in 1975.
It had a monoshock rear end.
2 GL1000s had been entered for the 75 Bol d'Or, one lasting till the 22nd hour, when something broke, the other breaking at 10 hours.
That's it folks, end of story, unless anyone has any more information!
