Apparently it’s viral video season and on the heals of BJ Baldwin’s Recoil4 launch lurks RJ Anderson’s fourth installment of the wildly successful XP1K series. The first three videos have had their staples for sure. In XP1K we saw Anderson break the world record for the longest gap jump in a UTV. XP1K2 brought us the Wall of Death and we saw RJ jump trains and through buildings in XP1K3. After a long wait, XP1K4 was finally teased today and promised to bring back the Wall of Death. This time around, the stable stunt of XP1K4 looks to be a backflip, which is the cliffhanger at the end of the trailer.
