Engineering Highlight: The FLHTCUSE series is historically significant for debuting the Screamin’ Eagle 110 cubic inch (1,803cc) V-Twin in 2007, but its most transformative update occurred in 2009. This year introduced the all-new touring chassis, featuring a single-spar, rigid backbone and a unique swingarm design that eliminated the high-speed "weave" associated with previous generations, fundamentally redefining the handling characteristics of heavyweight American tourers.
Technical Review: The Pinnacle of Project RUSHMORE Precursors
The Custom Vehicle Operations (CVO) Electra Glide Ultra Classic (FLHTCUSE) represents the zenith of Harley-Davidson’s luxury touring lineup between 2006 and 2013. As the Editor-in-Chief of MotoSpecsLab, I categorize this machine as a high-torque masterclass. The integration of the Twin Cam 110 engine provided the necessary grunt to move nearly 900 lbs of motorcycle, chrome, and rider with effortless authority.
Key mechanical advancements during this era included the transition to Brembo triple-disc brakes and an optional ABS system in 2008, which addressed the stopping power limitations of earlier models. The electronic throttle control (Fly-by-Wire) introduced in the same period streamlined the cockpit and allowed for more precise cruise control integration.
Maintenance Guide & Operational Specs
Fluid Requirements
The FLHTCUSE demands high-viscosity thermal protection. We recommend SAE 20W50 synthetic oil. The dry sump system requires 3.8 Liters for a full change including the filter. For optimal clutch performance, ensure the primary chaincase is serviced with H-D Formula+ or an equivalent heavy-duty lubricant.
Tire and Chassis Setup
Proper tire sizing is critical due to the 2009 frame change:
- 2006-2008 Models: Front MT90B16 72H / Rear MU85B16 77H.
- 2009-2013 Models: Front 130/80B17 65H / Rear 180/65B16 81H.
Maintaining a pressure of 36 psi (Front) and 40 psi (Rear) is non-negotiable for preserving the integrity of the sidewalls under heavy touring loads.
Electrical System
The high-output charging system on the CVO models supports heated seats, grips, and advanced audio. Ensure the 66010-97D (or the updated 66000212) battery is kept on a tender during off-seasons to prevent the parasitic draw from the security system and ECU from depleting the cells. Spark plugs should be gapped according to HD 6R12 standards to ensure complete combustion in the high-compression 110ci cylinders.
Expert Verdict
The FLHTCUSE is a collector-grade touring machine. While the 110ci engine is known for heat generation, proper maintenance of the oil cooler and the use of high-quality synthetic lubricants mitigate these concerns. For the rider seeking the ultimate blend of Milwaukee iron and modern luxury, the 2009–2013 iterations remain the gold standard.
