I recently rode a new HD Dyna Wide Glide. A friend bought one and let me take a cruise around the block.
Now, before I give my impressions, I must disclose that I own a 2005 Yamaha Road Star Silverado. It is as close as you can get to HD without actually buying HD. I never ride it and it will be up for sale soon. Too weak compared to the Busa, and the handling, well...
So, now comes the HD. I had actually considered buying one. Long story short, the HD makes the Roadie seem like a sport bike. The Yamaha has more power, better handling, build quality at least as good or better and it costs way less. If I were to become enamored of cruisers again, with the current offerings, I'd go with Yamaha, but with the Roadliner or Stratoliner this time (1800cc, fuel injection, aluminum frame).
Of course, if you have to have a Harley, there is no substitute.
