The Project RUSHMORE Milestone
The 2014 FLHTCU marks a pivotal moment in Harley-Davidson’s engineering history. It was the flagship year for Project RUSHMORE, a massive four-year product development effort driven by thousands of hours of customer feedback. This was not merely a facelift; it introduced the High Output Twin Cam 103 engine and the revolutionary Splitstream vent in the Batwing fairing, which reduced head buffeting by 20% compared to previous iterations.
Engineering & Performance Overview
At the heart of the 2014 Ultra Classic is the High Output Twin Cam 103™. This powertrain was specifically tuned to deliver more low-end torque, facilitating easier passing maneuvers and better performance when fully loaded with a passenger and gear. The chassis features 49mm telescopic front forks, which significantly stiffened the front end for improved cornering precision over the 2013 models.
Maintenance Guide & Technical Specs
Lubrication System
For optimal thermal stability, MotoSpecsLab recommends Harley-Davidson 360 20W50 for standard use or Screamin’ Eagle SYN3 Full Synthetic for high-temperature environments. The system requires 3.8 liters (approx. 4.0 quarts) when performing a full oil and filter change.
Chassis and Contact Patch
The FLHTCU/14 utilizes a specific tire combination designed for heavy touring. The front 130/80B17 and rear 180/65B16 must be maintained at 36 psi (2.48 bar) and 40 psi (2.76 bar) respectively. Maintaining these pressures is critical for the Reflex™ Linked Brakes with ABS to function within factory parameters.
Electrical and Ignition
The electrical system relies on the heavy-duty 66010-97D battery. For ignition, the 6R12 spark plugs should be gapped precisely between 0.97 and 1.09 mm. Standard maintenance intervals suggest inspection every 5,000 miles to ensure combustion efficiency.
Editorial Review: The MotoSpecsLab Verdict
The 2014 Electra Glide Ultra Classic remains one of the most balanced touring machines on the secondary market. By combining the classic air-cooled aesthetic with modern aerodynamic improvements and the Boom!™ Box infotainment system, Harley-Davidson successfully bridged the gap between heritage and utility. From a technical standpoint, the increased fork diameter and improved cam profile make the 2014 model a superior choice over its predecessors for long-distance reliability.
