LARIO
Description Street circuit used from 1921 to 1939 for important motorbike races and it was abandoned because it was too dangerous (besides reason, of course).
Lario is the latin name of Como Lake
Map is drawn using an original road map dated 1927 and profile (surely inaccurate, as it is 3 km shorter) is taken from a guide dated 1927.

My map seems ti have some difference with ones on official website, but I can’t understand how it is possible, as on 1930 road atlas there are no more roads.
