I've been riding one of Charlies' 660 Rallyes around town (CA. plated don't 'cha know), and it's amazing the responses I get from people who either know what it is, or have no idea at all.
I had one guy ask me if I knew what I had in the back of my truck! I assured him I had some idea.
But by far the most common question (and my favorite) is simply "Why?".
Because it's cool. Because it's been there. And done that. Because I never will be there or do that. Because I can live vicariously through the stories the bike would tell me if it could.
And becasue it's still a really, really capable dirt bike!
Congratulations on a very cool project. I'm subscribed.
