I currently have a XB12r and love every minute of it. However I am interested in purchasing a bike to take to the track and not beat up my XB. I would really love an EBR but do not want to have it be my first track bike so I am toying with the idea of getting an 1125r for that purpose as well as riding the hell out of it of course. I just have a few questions for those of you who know your stuff on them. What are the differences in the years produced? I know the XB had some upgrades throughout the years, are there any with the 1125? Are there any specific things I should look/listen for when looking around? Years to get or stay away from? Are the rotax motors more difficult to work on? And suggestions or advice is much appreciated.
