Hello, I am looking to buy a used on/offroad bike. Besides riding on the street I will also be doing some light trail riding. I have found a 1986 KLR600 in my area for $1500. It is in excellent shape. Is this a good bike? How is it's relaibility and performance? Also does $1500 sound about right? Any other info you can give is greatly appreciated!! Thanks in advance......Mike
