It's old school vs. new school as Paul Sr. and Paul Jr. continue their competition to build OCC's next production bike. With OCC's expansion underway, Paul Sr. keeps it all in the family as he approaches the third Teutul son, Danny, to get him on board with the construction of the new building. As the Teutuls' new book hits the shelves the guys go on the road to show appreciation to their fans. With the builds nearing completion, both teams get down and dirty in the mud to settle an old score. The finished bikes head to the grand opening of OCC's first dealership, and the final vote to determine which bike will be OCC's next production chopper.
