it can be depends on which one you get. as far as like the sprockets and if its been bored out. i have a 97 cr125 with 2 teeth smaller on the front sprocket and 2 teeth bigger on the rear. its also been bored out to about a 140. its ok on the trails i would get softer suspension thats the only thing that makes riding trails on a 125 race bike a little more interesting

Nothing is more fun than a two stroke. I myself was raised riding an '86 XR 100. I was out of riding up until about a year ago when I finally broke down and bought an '03 YZ 250. I have found myself back into a sport that I wished I'd never left. I ride everyday and find myself with an obsession with getting faster and quicker times through the woods. This has put a very tight strain on my relationships with former girlfriends. Notice I said former. LOL! I plan on entering my first hare scramble or enduro next spring. As for answering your question 125 or 250, I can't give you that answer. You'll have to make that choice yourself. All I can say is do yourself a favor and buy a smoker(two stroke). You won't be disappointed. This has been the best investment I've ever made.
I almost exclusively ride my KX125 as a trail bike. I love it. If you are only 14, a 250 is too big. I was still riding my xr80 at 14, and I beleive it wasnt until like 15 until the first friend in our group of riding buddies got a 2 stroke 80 which changed the world or riding for us as we knew it :)
ya i think a 125 would be just right. you will probably love the 2 stroke. the only thing you always have to do is mix the fuel. the only time my two stroke has broke on the trails was because of me i didnt tighten down the seat bolts so half way through the ride my seat fell off. haha any ways i think if you go any bigger then a 125 you will have a hell of a time
