2006 BIG DOG MASTIFFYou are looking at a Big Dog Mastiff with 10. 32 miles on it. It is black cherry and powered by an S&S 117-inch. overhead-valve. air-cooled. 45-degree V-Twin engine and driven by a Baker 6 speed transmission. The bike comes with 2 main seats (original and pushup). detachable rear seat. sissy bar w/back pad. Big Dog bike cover. low profile bike jack. and a Big Dog bag that mounts to the sissy bar for storage. There are no dents or dings that I can find. There are some small scuffs on the tank. All chrome and aluminum is in excellent condition. Both tires have good tread left on them.
