Scuzzlebutt,
STOP!!!
What type of experience do you have riding? If you are a beginner, the YZ isn't the best choice.
Are you looking at the YZ 125 or 250? That makes a big difference in the woods and trails.
Before you go buy a YZ look at the KDX 200. It is an awesome all around bike for the pleasure rider. It can go in the woods and trails very well, and easily handle the track for a "just for fun" rider. it is much easier to ride and learn on tha a YZ and cost is much less. Plus as you get better and desire more from a bike, the KDX can take on some very simple Modifications to make it a juiced machine. Do yourself a favor and at least look at the KDX
