Anyone know of any forums like this for street cruisers--looking at Kawasaki Vulcan 1600 or Yamaha Star

 

Did a google search for "street bike forums", and this is a couple that it gave me...you may be looking for something else, though.

sportriders

and

Motuonline

The best 2-wheel site I know is Dirtrider but I think it's all dirt. I've never checked to see if they have a street section.
