The history of green Moto Guzzi reportedly dates to Ing. Carcano's racing management in the late '40s and '50s. It has been said that Carcano was so obsessed with weight that he forbade painting the race bikes. Metal was left in the raw state or primed, commonly with zinc chromate (which exhibits a more greenish-yellow, perhaps the 'reference" for the metallic "Legnano Green " applied to the original Telaio Rosso V7 Sport of early to mid '70s and, later, at the introduction of the V11 Sport).
What we commonly call "Tenni Green" is a luscious, rich satin spruce green (more blue-green than yellow-green) introduced on the 2002 V11 Tenni.
Since then, this rich, spruce green has been applied to Stelvio, Griso, Centenary Special Editions, and now the V100 Mandello (although that "Mandello Green" looks decidedly glossier) . . .
Perhaps it has become as enigmatic of "Guzzi" as our v-twin?
I wonder if it is only the V11 community that refers to this as "Tenni Green?"
