not sure about everyone else, but for me, the first time i saw one, was 'wtf is THAT thing'
Funny thing is the first one I saw I'm pretty sure is the one I bought, several years later!
I was at a gas station on my 'screaming 650 Yamaha classic silverrado' when this guy comes tooling in on a black Valk with 6-6 pipes and I thought "how cool is that thing with the 6 'slash-cut' pipes!
Tried to talk to the guy but he wasn't interested in a conversation.
Many years later I bought my bike from my daughters FIL who is not a "ball of conversation".
So putting it all together (black bike, slash-cut pipes, owner not too talkative) plus Valks not the most abundant bikes around and even less with 6-6 pipes...
