I've been on the fence since last year, but now its driving me nuts. I currently have a 2005 YZ125. I can ride it fairly good, and I'm very comfortable on it. My goal is to buy a brand new bike, or at least pretty damn close. I want to stick with 2 strokes (personal preference.) I had the idea to put a 144 kit into the bike over the winter, and go on from there. I also have been thinking about getting a 250 2t. I love the 250's power, but it can be a handful. I'm only 17 years old and weigh about 140lbs. Thanks for any feedback!
