I am kinda new to dirtbike riding. Over the summer I began to ride dirtbikes, and all I had at my house was a little KC 70cc Pitbike. So I was wondering if you guys think a 125 would be good for me (I prefer Trail Bikes/4 strokes) I am 5'10 and 147lbs. If you do not think this is an appropriate size bike or If you think a different bike model is better please let me know. Thanks 
I love to go up hills, and do little jumps (still getting the hang of jumping)
