Welcome to SoCal XR's, America's first motocross club dedicated to 4-stroke mini-bikes. We will begin our club again soon via Facebook..  We're all about pretty much any 16" rear - 19" front 2 valve air-cooled mini-bike.  We have been working on TTR125's lately and are in the midst of putting together some "how to's".  Check out our tech section, it's starting to get a lot of articles. If anyone has anything to contribute we are always happy to take submissions.
