The Ridgeback has returned to Big Dog's Chopper line with a vengeance after not making the cut last year. Who says the fat tire revolution is dead? Not Big Dog. In fact, it's going wider than ever before on the Ridgeback, a whopping 330mm low-profile rear tire. For the rigid frame to accommodate the foot wide rear, BDM had to do a little redesigning. The 8-inch oversized down tubes are an inch bigger in comparison to last year's Chopper and the 4-inch oversized backbone measures an inch bigger as well. At the opposite end to the 330 mm rear up the 82.5-inch wheelbase is a 21-inch custom-designed front wheel sitting way out on a 12-inch oversized fork. The classic chopper-style rake, a healthy 39 degrees, is up two degrees from BDM's '07 Chopper. Overall, the belt-driven 680 lb bike is an inch short of nine feet.

"The Ridgeback buyer is someone looking for the most rebellious design and hardcore looks in a rigid custom cruiser and the fattest tire on the market combined with tremendous excitement, performance, and handling," said Messer.
