Hi, I am considering buying a used Concourse (I have owned a Honda sport bike and currently own a KLR650). I have a few initial questions I was hoping someone can help me with. 1.I have recently heard the model number GTR1000, is there such a number as ZG1000 and what are the differences? 2.Which model would you recomend and why? 3.I really like the red color, what years was this bike produced in red? 4.Are the saddle bags water proof? 5.What is the miles per gallon on the highway? Thank you for your help!
