A milestone happened sometime in the last hundred miles or so. I noticed it on my way home from The Joint's Hog Feed today (pics to come - don't worry).
My Sportster is my first bike and I bought it used in the fall of 2006 with almost exactly 8,000 miles on it. Over the past few days, the odometer passed 28,000 so I have officially ridden my Sporty 20,000 miles.
Here's a pic of when it was brand new (to me) in October 2006. It was completely stock except for the sissy bar.
In case you're curious, my Road King has nearly 16K on it (14K are mine, and 2K are my dad's from our trip to Sturgis last year).
