2015 Harley-Davidson Tri Glide Ultra Classic FLHTCUTG, Trikes are bound to ride a little differently than two-wheeled machines. But when theyre done right, they have a joy of their own. Harley-Davidson uses legendary engineering and ride dynamics to keep you comfortable and connected to the road. This three-wheeled pioneer is built from the ground up for maximum handling. The frame and chassis structure is engineered to specifically handle the steering forces and weight of a three-wheel vehicle. And we defy you find a more comfortable ride on the touring circuit from two to four to eighteen wheels.
