Same thing happened to me yesterday - honda shadow pulled up beside me and said nice bike, I replied with a thanks and road off.
My normal reply is always Thanks

 

If I tell someone they have a nice scoot, and he says "thanks", it's 'nuff said...

 

I always look at them and say I like it, or I think it is.

 

It all depends...

If you are a dude...then "Thanks" would do.

If you are a chick....it depends on the time of the month.....

Oh, ****......flame on !

 

That won't get you laid if it's a chick.

 

"ya, i know"

 

Usually the comments are about the color, blue. I just say "Thanks, that's why I bought it". And that's not entirely untrue.

 

That's funny, because when I had my sportster, I never had anyone say nice sportster, it was always "nice bike, is that a fatboy?, or hey, nice night train. Is that one of those V-rods?"
When I got my dyna, all I started hearing was "nice sportster", and "cool bike, is that a sportster?"
When people compliment my bike, I just say "thanks", no matter what they think my bike is, lol.

 

I pause.... Yep...The b**** loves to be ridden hard.

 

I like "Hey azzhole, would you say nice woman if I was with my wife or girlfriend? Don't get fuggin' personal about my bike".
