Okay, So here's my bike background. I had a 2005 yz125 for a few months, raced it in 125 C class and had alot of victories. I sold it and got a 2007 rmz250. I rode it 3 times and when i raced it for the first time, the crank seized on me. So it pretty much blew. I am NOT fixing that 250f. Wayyyy too much money. I'd rather go back to two strokes, I can work on those allll day. So I weight 175-180 lbs. I am 6'1 or so and I race C class, and I'm usually up front. I really want to ride/race again. I don't know if I should get a 250 2t or a 125 2t. Either way, I can only spend up to 2000 dollars or so. If you need feedback or more info just ask! But please help me out here!
