The right hand turn signals (looking from the back) are drooping..and the left hand bar end is all scraped up. Defintely been in an accident. When you look at the FZ6's back rear fender, the above poster is right, the whole tail section looks bent, likely the sub frame.
I think its a crime that he has not disclosed the accident damage.
One of the last pics also shows a black sport bike with the front fairing smashed. This guy must buy wrecked bikes and fix them up. I would never pay $6500 for a used bike with damage when I can walk into a dealership and pay that for a brand new bike out the door.
