Also released for the 2009 model year is the FLHTCUTG Tri-Glide Ultra Classic, the first three-wheeled Harley since the Servi-Car was discontinued in 1973. The model features a unique frame and a 103-cubic-inch (1,690 cc) engine exclusive to the trike. The changes result in greater load carrying capacity, better handling, a smoother engine, longer range and less exhaust heat transmitted to the rider and passenger.
