Looking at a 2000 ZR-7 with Yoshimira exhaust and 5800 miles. Dealers is asking 4800. I want to offer him 4200 out the door. What is a reasonalbe offer? Are there any major flaws with the 2000. I am a new rider. Most of my limited experience is on a yamaha 250 dirtbike. But I love the feel of the ZR-7. Any help or opinions would be appreciated.
