The 2006 MY Big Dog K9 has, at its heart, an air-cooled, four-stroke, 1916cc, V-Twin engine paired to a six-speed manual transmission. It boasts standard features such as a raked-out front end with a 41mm telescopic fork, dual shocks as a rear suspension, a single seat, a chromed, two-into-two exhaust system, lightweight, cast-aluminium wheels, front and rear disc brakes with PM calipers, a custom paint scheme and an analogue instrument cluster.
