Both treadmills have six preset workout programs, including cardio training and fat burning modes. You can also create your own custom workout programs as User 1 or User 2. The red LCD display of the F80 treadmill shows the speed, incline, time, distance traveled, calories, pulse and pace, like the F63's blue LCD. The Sole F80 has a 3.0HP motor (an improvement over the F63's 2.5HP motor), cushion flex shock absorption whisper deck (an improvement over the F63's phenolic shock absorption deck), and a wider range of speeds than the F63 (0.5-11 mph as opposed to 1-10 mph). However, it lacks the higher end F83's larger running surface (20" x 58" compared to 20" x 55"), reinforced framework (which makes for a higher user weight limit), and heart rate zone graph on the console. The Sole F80 comes with a lifetime frame and motor warranty, a five year parts warranty, and a two year labor warranty (a warranty that is better than the F63's).
