Racer X Films: 2003 Kawasaki KX125 Build

This 2003 KX125 was in great shape and a perfect find for a project bike. The frame paint on this bike looked like it was brand new. We can only imagine that whoever owned this bike rode it around a few times, fell over and scraped his elbow and then sold it. God bless that guy. We didn’t go crazy with modifications on this bike because we wanted to keep it reliable and easy to tune. The crazier you get with cylinder and head mods, the fickler the jetting becomes. This machine took us right back to 2003 and reminded us just how fun this bike was.

*Jetting from the Pro Circuit.
