The K-9 continues to be the flagship of the Big Dog fleet. In its third year in production, the nine-foot-long chopper shares much in common with its sibling the Ridgeback. Its frame has the same stretch, the rake angle has the same ridiculous 39 degree setting, and the forks are a sick 12 inches oversized. The one-piece steel tank design is a constant denominator between the two as is the 24.25-inch seat height. But the K-9 has something the Ridgeback doesn't. Rear suspension. The hidden shock is adjustable for loads but maintains its custom appeal by not raising the rear fender away from the tire. It's also pre-wired to accept an aftermarket air ride suspension, a common feature in custom show bikes this year. The chopper's A-Frame swingarm houses a 300mm rear tire, not quite the girth of the Ridgeback's but still plenty of rubber to lay down on the road. And while all Ridgebacks run a Super G Carb, K-9 owners have the choice of EFI or carburetion. Overall, you won't find a more classic-looking chopper than the K-9, though 300mm rears are definitely a touch of the new-school of styling.

Big Dog Motorcycles hasn't been in the biz for 14 years by not being smart. Making bikes more people can afford and establishing a novice-level ride are moves in the right direction to staying afloat in an industry where more vessels sink than swim. The Wichita company is also in the process of establishing a Dealer Support Center to provide the sellers of its bikes an avenue for hands-on technical and service training. Along with its revised Technician Education Program, these new Big Dog techs and reps are going to be an educated lot that will work to the benefit of consumers. Who says you can't teach an old dog new tricks?
