I've heard it all, since I started out on a Honda Shadow, and currently ride a '17 Willow Green/Cream Roadmaster.
Shadow- "That's a girl's bike"..."when are you going to get a bigger bike?"..."when are you going to buy an American bike?"...on and on...
Indian- "Nice POLARIS!"..."You know that's not a REAL Indian, right?"...some HD riders won't even acknowledge me when I say "Hi", but their buddies on metric bikes will. Ride to the CVMA Nationals, and Indians made up maybe 10% of the bikes there.
My standard replies vary... "what do you ride...wait, let me guess... a black Street Glide?"..."you know AMF bought HD back in the day, and they were making snowmobiles long before Polaris came along"..."you're just cranky because your bike spends more time in the shop than on the street"..."hey, man, that's a nice FLXHLGBTWTFBBQ you got there!"
What's funny is that, no matter where I ride, my bike gets all the attention, especially when I was stationed in Germany. I had the only WG/C Indian Roadmaster in Bavaria. When I went to the Indian Rider's Fest in Czech, I was one of three WG/C Roadmasters, and the fest had riders from all over Europe. When I walk out into the parking lot, I can always tell where my bike is, even in a sea of other bikes.
