2011
The 2011 Big Dog K-9 is a quintessential American custom cruiser, representing a significant model in Big Dog Motorcycles' lineage of large-displacement, factory-built choppers. Known for their stretched frames and powerful V-twin engines, Big Dog carved a niche for riders seeking a distinctive, low-slung aesthetic combined with a robust powertrain. In its class, the K-9 directly competed with other high-end custom manufacturers like American IronHorse and some of the more custom-oriented models from Harley-Davidson's CVO line, offering a unique blend of style and power for those who wanted to stand apart from the mainstream.
At the heart of the 2011 K-9 lies its substantial V2, four-stroke engine, boasting a displacement of 1917.0 ccm (116.98 cubic inches). This large V-twin unit provides ample torque, characteristic of power cruisers, ensuring strong acceleration and a commanding presence on the road. The motorcycle’s dry weight comes in at a hefty 318.0 kg (701.1 pounds), underscoring its substantial build. Fuel capacity is generous, with a tank holding 16.60 litres (4.39 US gallons), allowing for extended cruises between fill-ups. While specific horsepower figures aren't always the primary focus for choppers, the K-9's engine is designed for effortless highway cruising and a satisfying V-twin rumble.
Riding the K-9 is an experience defined by its classic chopper ergonomics. The low-slung seat, with an adjustable lowest setting of 616 mm (24.3 inches), places the rider deep within the motorcycle, contributing to a planted feel. The stretched wheelbase and raked-out front end, typical of the chopper style, provide stable highway manners, albeit with a more deliberate steering input at lower speeds. This setup prioritizes a relaxed, long-distance cruising posture, making it well-suited for eating up miles on the open road. The forward controls and wide handlebars further reinforce its laid-back cruiser identity.
The 2011 Big Dog K-9 was built for the rider who values individuality and a bold, custom aesthetic straight from the factory. It appeals to enthusiasts who appreciate the raw power of a large V-twin and the distinctive presence of a stretched chopper. This isn't a motorcycle for quick maneuvers or track days; rather, it’s designed for making a statement and enjoying the journey with a unique, custom-built machine. The K-9 serves as a testament to American custom motorcycle artistry, offering a compelling package for riders seeking a powerful, eye-catching cruiser.
