In 15 years of Guzzi riding, never got the Ducati thing.
But all sorts of other reactions, of course.
One of the funniest was that of the parking attendant at a race circuit, writing down all the brands and registration plates of the visitors. Must have been early 2000.
A Kawadasuki 458 crf, a Yamizuda 785 vvf. The young man could classify them all without any effort. In my eyes stunning, since they all looked alike to me.
Then I came on my EV. Problem was, I had the tank bag on, so no visible brand name.
I never forget his face and his extreme confusion when I tried to explain what I was riding. ;D
After asking 4 or 5 times, he gave up. I still don't know what he wrote down :D
