We test a 2017 KTM XC 300 that project bike builder Jay Clark updated for the 2018 EnduroCross Ride Day at MotoVentures in Anza, California. So we put test rider Allan Brown at the controls of the orange off-road bike to determine how the bike differed with a Keihin 38mm PWK Airstryker with a JD Jetting kit installed.
