BMW R 50/2 Episode: 1.14
Maico MC250 Episode: 1.3
MC. Pas GS... Looks like 1972 Maico MC360 with non standard Montesa two leading shoe front brake.
BMW R 60/5 Episode: 1.7
all we get to know about is it is going faster than 10 seconds 0-100Km/h It's a /5 series, with those performance figures I'd suggest an R60/5 (8.2 sec's 0-100) as the 750 was considerably faster (6.4 sec's). that would fit perfectly
Autre indice quand même nettement plus pertinent que trois lignes de dialogue, les câbles de gaz qu'on distingue. Et qui suggèrent des carbus à boisseaux, et non à dépression. Donc R 50/5 ou R 60/5...
