- The Dyna designation is gone. The former Dyna and Softail models will now share a common frame, all under the Softail family name.
- The new frame is lighter, simpler, and stiffer, with a triangular swingarm unit pushing directly on a monoshock/spring under the seat (shades of my old Vincent Black Shadow), rather than using the conventional swingarm/twin shock layout of the Dyna or the push/pull spring units under the engine of the previous Softails.
- Milwaukee-Eight V-twins of 107 and (optional) 114ci will be used, now rigidly mounted in the frame for added stiffness, with twin counterbalancers to reduce chassis vibration. Oil-cooling only; no water for the Softail line. Both engines make more power than ever before.
- Engine oiling is now by wet sump, eliminating the traditional separate oil tank under the seat. This puts less heat into the rider, battery, and frame and also frees up room for the monoshock under the seat. The engine itself is tilted slightly forward to raise the rear primary drive casting and make it possible to have more cornering clearance on all models.
- Every part on the bikes has been redesigned to reduce weight, taking about 32 pounds off most models.
