During last weekend’s AMA Supercross 450cc main at Arlington Honda’s Justin Barcia gave KTM’s Ken Roczen a whip with some serious attitude following a previous mid-corner tussle.

Onboard footage from Roczen has been released that shows just how close Barcia’s rear tyre came to Roczen’s front as he showed his displeasure and attitude in quite a unique way! Will the antagonism continue at Georgia Dome this weekend…?
