Engineering Highlight: The 2013 FLTRXSC2SE holds a distinct place in motorcycle history as the first CVO model to feature the high-intensity Daymaker™ LED headlamp as standard equipment. This marked a significant shift in Harley-Davidson’s engineering philosophy, prioritizing active safety and electronic sophistication alongside the raw power of the Screamin’ Eagle 110 cubic inch powertrain.
Technical Review: The Pinnacle of the Shark-Nose
At MotoSpecsLab, we categorize the FLTRXSC2SE as a ‘Masterclass in Factory Customization.’ The heart of this machine is the air-cooled Twin Cam 110 V-Twin, producing approximately 118 ft-lb of peak torque at 3,750 RPM. The integration of the Heavy Breather intake and high-flow exhaust ensures that the volumetric efficiency matches the aggressive aesthetic of the shark-nose fairing.
Maintenance & Fluid Dynamics
For optimal thermal management in this high-displacement air-cooled engine, the use of SYN3 Synthetic 20W50 is non-negotiable. With a capacity of 3.8 Liters, the synthetic lubricant provides the necessary shear stability required for the 110ci engine’s high operating temperatures. Owners should adhere to a strict 5,000-mile (8,000 km) interval for oil and filter changes to prevent sludge buildup in the hydraulic lifters.
Ignition and Electrical Systems
The 2013 CVO utilizes the 6R12 spark plugs. Proper gapping and torque are essential to prevent pre-detonation in the high-compression cylinders. Power is managed by the 66010-97D battery, which provides the high cold-cranking amps (CCA) necessary to turn over the heavy rotating mass of the Screamin’ Eagle crank.
Chassis and Handling
The wheel configuration—a 19-inch front and 18-inch rear—strikes a balance between agility and touring stability. To maintain the structural integrity of the sidewalls and ensure predictable cornering, tire pressures must be maintained at 36 psi (Front) and 42 psi (Rear). Under-inflation on this 800lb+ machine leads to accelerated cupping and compromised braking distances.
Frequently Asked Questions (FAQ)
Q: Can I use mineral oil instead of SYN3?
A: While possible, it is not recommended for the Screamin’ Eagle 110 engine. The synthetic 20W50 provides superior protection against the high heat generated by the 1803cc displacement.
Q: What is the significance of the FLTRXSC2SE designation?
A: It denotes the Road Glide Custom (FLTRX) as a CVO (SC) Special Edition (2SE) for the 110th Anniversary production cycle.
