2007–2008 Harley-Davidson Dyna CVO Twin Cam 110 (FXDSE Screamin Eagle Dyna)

The CVO program’s mission is to take standard production models and transform them into highly customized, feature-rich machines. The Screamin’ Eagle Dyna was a stark departure from the standard Dyna models of its era, primarily the Dyna Super Glide, Street Bob, and Low Rider. The most significant difference was the powertrain. While standard Big Twin models in 2007 were equipped with the 96-cubic-inch (1584cc) Twin Cam engine, the FXDSE featured the massive 110-cubic-inch (1803cc) Screamin’ Eagle Twin Cam engine. This upgrade provided a substantial increase in torque and horsepower, delivering immediate and forceful acceleration that set it far apart from its showroom siblings.

Development and Design

The concept behind the FXDSE Screamin’ Eagle Dyna was to create the ultimate performance-oriented cruiser. The Dyna platform, known for its twin external shock absorbers and rubber-mounted engine, was already prized by enthusiasts for its superior handling characteristics compared to the Softail and Touring lines. Harley-Davidson’s CVO engineers leveraged this foundation, enhancing it with premium components and the formidable Twin Cam 110 engine.

The design philosophy was one of “more is more.” Every aspect of the standard Dyna was scrutinized and upgraded. The suspension was improved for better compliance and control, the brakes were enhanced to manage the increased power, and nearly every visible component was either chromed, powder-coated, or replaced with a custom-milled billet aluminum piece. The result was a motorcycle that looked as potent as it performed, with a fit and finish that rivaled aftermarket custom builds.

Key Features of the 2007–2008 Harley-Davidson Dyna CVO Twin Cam 110

Powertrain: The Screamin’ Eagle Twin Cam 110

At the heart of the FXDSE is the air-cooled, 45-degree Screamin’ Eagle Twin Cam 110 V-Twin engine. This 1803cc powerhouse was equipped with Electronic Sequential Port Fuel Injection (ESPFI) and was paired with Harley’s 6-speed Cruise Drive transmission. The engine was tuned to produce a massive wave of torque, peaking at approximately 110-115 lb-ft, making it one of the most powerful production Harley-Davidsons of its time. The powertrain was finished with extensive chrome and color-matched engine head covers, highlighting its status as the bike’s centerpiece.

Chassis and Styling

The FXDSE utilized the robust Dyna frame, but it was adorned with numerous CVO-exclusive components. It featured 18-inch spun aluminum “Revolver” wheels at the front and 17-inch at the rear, shod in performance-oriented Dunlop tires. The front end was distinguished by 49mm forks and a chrome low-profile front fender.

Styling was a major focus. The bike came with factory-installed forward controls, a low-profile two-up seat with a custom insert, and a unique color-matched frame and swingarm. The most striking feature was the paint. CVO models are renowned for their intricate, multi-layered paint schemes, which are unavailable on any other Harley-Davidson model. Each year offered distinct color combinations, applied by hand, making every FXDSE a rolling piece of art. The attention to detail extended to the smallest parts, including a chrome-and-rubber collection for grips and pegs, a flush-mount fuel cap and LED gauge, and a host of other Screamin’ Eagle branded accessories.

Model Year Variations

While mechanically similar, the 2007 FXDSE and 2008 FXDSE2 are primarily distinguished by their exclusive paint options and badging.
