I currently have a DRZ400SM, and its a great bike, but I want something more. The first bike I was looking at to convert was a 2008 KLX450R. It seems like a pretty good bike, but were I live they are pretty hard to find. On the other hand, I have a guy willing to trade me a 2008 KTM450XC-F for my DRZ. This thing also seems like a nice bike. The KTM is lighter and probably more powerful than the KLX, and both the bikes will require more maintenance than the DRZ. I would really like to have the KTM, but i'm worried that the maintenance will be too ridiculous. Odds are the bike will never see a track, and will just be ridden on the roads about 5 times week. What is the maintenance like on the XC-F, and would it even be worth beeing a street ridden supermoto?
