Of course, here is a full article about the 2011–2016 Harley-Davidson Touring Twin Cam 103 (FLHX Street Glide), written in the requested style.
The 2011–2016 Harley-Davidson Touring Twin Cam 103 series, epitomized by the FLHX Street Glide model, represents a significant era for the American motorcycle manufacturer’s touring lineup. This period saw the introduction of a larger, more powerful standard engine and a host of technological and ergonomic refinements that solidified the Street Glide’s position as a leader in the factory-custom bagger category. Bridging the gap between the earlier Twin Cam 96 and the subsequent Milwaukee-Eight engine, the Twin Cam 103 models offered riders a sought-after blend of traditional Harley-Davidson character and increased modern performance.
Evolution from the Twin Cam 96
The most substantial change from the preceding 2007-2010 models was the move from the Twin Cam 96 engine to the Twin Cam 103 as the standard powerplant for the touring family starting in 2011. The previous generation offered the 103 cubic inch engine only as a paid upgrade. This transition brought a noticeable improvement in performance, primarily in torque.
The Twin Cam 103 featured a displacement of 103 cubic inches (1,690 cc) compared to the 96 cubic inches (1,584 cc) of its predecessor. While horsepower figures were not drastically different, the larger displacement provided a significant increase in low-end and mid-range torque. This resulted in stronger acceleration from a standstill, more responsive roll-on power for highway passing, and a more capable feel when riding with a passenger and luggage. The 103-equipped bikes also typically came standard with an integrated oil cooler, which helped manage engine temperatures more effectively during long rides and in heavy traffic.
The Heart of the Glide: The Harley-Davidson Touring Twin Cam 103 Engine
The Air-Cooled Twin Cam 103 is a 45-degree V-twin engine that maintains the classic Harley-Davidson architecture, including pushrod-operated overhead valves. It was paired with Electronic Sequential Port Fuel Injection (ESPFI) for reliable starting and crisp throttle response, along with a 6-Speed Cruise Drive transmission that provided a low RPM for relaxed highway cruising. The engine was rubber-mounted to the frame, isolating the rider from excessive vibration at speed while still delivering the characteristic V-twin pulse at idle.
Beginning in the 2014 model year, the engine was upgraded to the “High Output” Twin Cam 103 specification. This version included a new camshaft and a high-flow airbox, which further boosted low-end torque and enhanced the motorcycle’s overall performance character.
Project RUSHMORE Enhancements
A pivotal moment for this model generation was the introduction of Project RUSHMORE for the 2014 model year. This was a comprehensive, customer-led development program that resulted in significant upgrades across the entire touring line, including the Street Glide. Key enhancements included:
Reflex Linked Brakes with ABS: This system electronically links the front and rear brakes to provide optimal braking force to each wheel, regardless of which brake control the rider uses. It was designed to improve rider confidence and control in all braking situations.
Upgraded Infotainment: The introduction of the Boom! Box 4.3 and optional 6.5GT infotainment systems brought modern connectivity to the forefront. These systems featured Bluetooth, USB connectivity, voice recognition, and GPS navigation on the premium version, all displayed on a full-color screen.
Redesigned Batwing Fairing: The iconic fairing was updated with a new “Splitstream” vent. This small, rider-operated vent below the windshield was engineered to reduce head buffeting by equalizing air pressure between the front and back of the fairing.
Ergonomic and Styling Updates: One-touch saddlebag latches simplified operation, while more ergonomic hand controls improved rider comfort. Many models also received brighter Dual Halogen or optional Daymaker™ LED headlamps for superior nighttime visibility.
Chassis Improvements: The front suspension was upgraded with stiffer 49mm telescopic forks, which provided more precise and responsive handling characteristics compared to previous years.
Chassis and Styling
The Street Glide’s appeal has always been its stripped-down, hot-rod bagger styling. Based on Harley-Davidson’s robust touring frame, the model features a low-profile stance, a clean rear fender, and color-matched hard saddlebags. The chassis was designed for long-haul stability, providing a planted and secure feeling on the highway. Air-adjustable rear shock absorbers allowed riders to fine-tune the suspension preload to account for the weight of a passenger or luggage, enhancing both comfort and handling.
