This is a 2008 crf250r motor. I was in the middle of building a race bike wile I had gotten layed off from my job so I am forced to sell cheap and quick. This is a ready to go bottom end with a brand new clutch kit from tusk[ fibers, steels, and springs] . The cylinder is in brand new condition with a brand new oem Honda piston kit [ piston, rings and pin and bottom cylinder gasket and head gasket . The clutch cover and ignition cover were just powder coated with fresh gaskets. Also just installed a Brand new k & n oil filter . bolt on a valve train and add oil and you will have a fresh running motor . This was a perfect operating engine before I disassembled to replace with new components so it will come with a extra piston and rings and a complete clutch all in perfect mechanical shape.  If you have any questions feel free to send a message. 

This 2008 motor will fit many other years.  Please check with your local dealer
