Up until 2015, I raced ATVs in a NC/SC cross-country racing organization and an occasional national race. From 2010 - 2015, I raced a Kawasaki KFX450R. I was one of the rare guys who rode a Kawasaki and I loved that.
XC stands for cross-country.
I'm 51 years old now so my days in the woods are done. My wife still thinks I'll go back before I'm 55.
