I am looking to get a 125 2t to play with on the mx track. I currently have a crf450r so the 125 is just to help me get better at carrying speed plus they are fun to beat on. Should I get a Yz125 or Ktm150. I was originally thinking a YZ125 then if I really liked the bike I would have Eric Gorr build me a 144 kit for it. However the KTM is already designed to be a 144 is KTM so is it any better then 144 YZ. I may race once or twice in the 250 class. Will the 150 keep up with a 250f accelerating down hard pack straits? I don't have any experience with ktm's are they reliable bikes. I would buy both bikes used so my top is $2000. How does a 02-04 compare to an 05+. The price between the years jumps easily $500-$1000.
