Professional Driver. One-Of-A-Kind Heavily Modified Vehicle. Do Not Attempt. You Could Die. "XP1K2" is a seven-minute onslaught of intense off-road road action, set in a massive 600-acre forest near Mt. Baker, Washington. The video stars Off-Road Racing Champion RJ Anderson, driving a custom Holz Racing built Polaris RZR XP 1000 Side-by-Side (SxS), complete with a Polaris ProStar® 1000 Muzzys Performance engine and custom Walker Evans Racing shocks.
