I work for Harley-Davidson. My first bike is my Yamaha. Did I catch a lot of flack? You bet! But, motorcycle lovers are motorcycle lovers, no matter the brand. It's hard to be loyal to just one when they've all got something exceptional.
H-D holds 50%+ of the U.S. large bike market-- of course there will be copycats! Leave it alone. Live and let live, gee whiz...
And on a side note:
I love my Yamaha-- it's perfect for me...it's small (I'm small) and it's my first bike with a small displacement (beginner level, YAY!). Harley's lowest CC bike (883) is too much for me right now and the Buell is just a little too cheesy, not my style...
