For sale is my fathers KTM 450SX 2003. The bike has 20 hours and has been barely used by my father. I was using it a few times and the last ride disrupted the engine with a value breaking a destroying the piston due to a bad adjustment. I took out the original engine and replaced it with a perfect condition 2004 sx engine. With the bike I'm also selling the original engine as a spare. The spare needs a new top end piston and cylinder. I do have the piston and the cylinder that I will include with the engine. The bike can be seen and tested anytime if you have any questions please feel freemtomcall me at 9174420353.
