Spacious carpet-lined luggage compartments, an air-adjustable touring suspension and passenger backrest added to the motorcycle’s functionality as a touring bike.
A 45 degree air-cooled V-twin, four-stroke engine powered the Ultra Classic, producing 81.1 foot-pounds (ft-lbs) of torque at 3,300 rpm.

A telescopic cartridge-style dampening front fork with 4.6 inches of travel comprised the front suspension, and air-adjustable shocks with three inches of travel made up the back.
