KX125AF KX144AF Build/Ideas

I have an idea to use a 250f frame and use a kx125 engine and suspension. All I have to go off right now are two pics of a KX144AF built in Italy. I can tell from the pics that they used the 125 subframe, rear numberplates, rear fender, and airbox. Does anyone know if they used a 250F seat? Also, does anyone know if i'll have to cut the cradle to accept the larger two smoker exhaust? Any comments are appreciated. :ride:



im sure the subframe was custom built, i dont think a steel frame kx subframe would just bolt right onto a 250f

most 2T AF conversion require making room for the pipe, so yes most likely will have to modify the cradle.

use a ktm 144 engine then that would be sweeeet!

It looks like they really needed to lift the motor in the frame as well. The lower engine mounts look extended for sure...

Does anyone know if they used a 250f frame or 450f frame? I'm guessing a 250f frame.

Does anyone know if they used a 250f frame or 450f frame? I'm guessing a 250f frame.

a 450f frame would kind of defeat the purpose, they use a 250f frame

Have you seen a bike like a KX125AF before? All I figured out this weekend is that they didn't need extra clearence for the pipe since it doesn't wrap around like the KX250AF and KX500AF's pipes. :ride: They even used the 125 swingarm, I know this because the swingarm has plugs in it and the 250f or 450f doesn't. The only question i'm left with now is about the seat. :lol: After I get this all figured out i'll start the build once I get the money. I really want the 250F handling characteristics without the 4-stroke maintence.

      Alright, found three bikes all located where i live in Texas. I know they're all very different, but if you could tell me what you think each bike is worth, and which one would be the best deal. Thanks.
      Notes: Both 2 strokes have new top ends. I think the front brake lever is broken on the kawasaki.
      KX250 2002 $800-$1000?

      YZ125 2000 $1250

      KTM 400SX 2002 $1200

      So I'm at a bit of a cross roads, I currently own a 06 rm250 and I love it. I also have a 02 kx250 which I'm selling with intent to buy a newer two stroke. I can't afford a newer ktm and the older ones aren't that great and kawasaki never impressed me. so I'm stuck between 06 yz250 and 05 cr250. I've heard the yz and rm after 06 are almost the same bike just the Suzuki handles better and the Yamaha has better suspension. So I'm not sure if I wanna buy carbon copy of my bike with slight differences. That's why I'm interested in a cr250 I heard the 02+ models RC valves are shit garbage but was mostly fixed in the 05-07 models. I ride at a track and at some bogs down the road from me. So from people who have owned both, what would you recommend. I know the cr is known for a hard hitting power band which I enjoy since im an aggressive rider. Should i just see which deal comes my way first.
