Some comments

These are the kerb weights (poids à vide en ordre de marche) I have found:

1974-75 1294cc 930 kg (base)

1976 1294cc 960 kg (base) Some difference to the chassis but hardly justify 30 kg

1975-76 1442cc 995 kg (S, Courrèges) 35 Kg difference. The engine which is about 1 inch Higger. And ... side windows electric motors, trim like feet rest, ... Could be justified

1977-78 1294cc 980 kg (base) To be compared to the 960 Kg = differences to the chassis + bumpers

1977-80 1442cc 1015 kg (S, Courrège, Jubilé, X) Here again 35 kg difference between the 1294 cc and the fully equiped 1440 cc

I'm currious about the real weight of Andy's racer

I suspect that the cage will have an adverse impact
