Handling-wise, a number of significant changes were made by PC in order to fine-tune the machine for the rigors of amateur national racing. Pro Circuit spared no expense in throwing DLC coating and aftermarket valving at the KTM's fork and shock, along with a Bladder Cap Kit, trick anodizing and fresh fluid. The sum of these changes is a suspension setup that better resists heating under race conditions while providing better action, increased bottoming resistance and improved rider feel. Basically, they took all of the KTM's stock suspension strong points and amplified them by ten.All together, the Pro Circuit KTM 65 SX is an insane little motorcycle with huge potential for racing applications.
