OCC Splitback Chopper S&S 124 V-Twin with a heart-pumping 2032cc of power. Just like the name implies…the tank on the Splitback is a 2-half design exposing the frames backbone while following the lines of the frame. Occ Crown rocker box covers Chromed wafer styled rocker box covers add style to an already sexy looking power plant. The control system on the Splitback is set in a middle position of the bike. This makes for better ergonomics for those longer rides and fits a bigger variety of rider body types better. OCC comfort seat system The OCC Comfort Shock Seat System on the Splitback chopper uses a shock mounted on the bottom of the seat pan wich is then attached to the frame. This aids in helping make a smoother ride while still maintaining the look of a rigid frame chopper.
