2005 KTM 125 SXEdit
KTM has been serious about 125 cc-class motocross, and this dedication has manifested in the 125 SX for several years now. The changes made by KTM put in production for 2005 have resulted in a greatly improved orange machine. As far as the engine is concerned, KTM left a good thing pretty much alone. It was the most-powerful 125 of 2004 and we expect that to be true in 2005.
