2007–2010 Harley-Davidson Dyna Twin Cam 96 (FXD Super Glide)

Of course. Here is a full article about the 2007–2010 Harley-Davidson Dyna Twin Cam 96 (FXD Super Glide), written in the requested style and format.

Increased Displacement: The primary difference was the increase in engine displacement from 88 cubic inches (1450cc) to 96 cubic inches (1584cc). This was achieved not by boring out the cylinders, but by increasing the stroke from 4.00 inches to 4.375 inches. The result was a significant boost in torque, which was immediately noticeable to riders in the form of stronger acceleration and better passing power.

Integrated 6-Speed Transmission: Paired with the new engine was the 6-speed Cruise Drive transmission. This replaced the previous 5-speed gearbox and was a major advancement for highway usability. The sixth gear acted as a true overdrive, lowering engine RPM at cruising speeds. This reduced vibration, improved fuel economy, and made long-distance travel more comfortable.

Standard Fuel Injection:** While Electronic Fuel Injection (EFI) had been introduced on some models prior, the 2007 update solidified its place as the standard fuel delivery system across the Dyna line, replacing carburetors entirely. This improved cold starts, throttle response, and overall engine efficiency while helping meet stricter emissions standards.

The Harley-Davidson Dyna Twin Cam 96 Engine and Powertrain

At the core of the motorcycle’s identity was its air-cooled, 45-degree V-Twin engine. The Twin Cam 96 produced a factory-rated torque of approximately 92 ft-lb at around 3000 RPM. True to Harley-Davidson’s philosophy, the engine was tuned for low-end grunt rather than high-revving horsepower, making it ideal for city cruising and highway roll-on acceleration.

A key feature of the Dyna platform was its rubber-mounted powertrain. Unlike the rigidly mounted engines in the Softail line, the Dyna’s engine was isolated from the frame by a system of mounts. This design allowed the engine to vibrate at idle—creating the classic Harley-Davidson character—but smoothed out significantly once underway, providing a more comfortable ride than might be expected from such a large V-Twin. Power was delivered to the rear wheel via a clean and low-maintenance belt drive system.

Chassis and Riding Dynamics

The Dyna frame was designed as a bridge between the nimble Sportster and the larger Touring models. It featured a traditional twin-shock rear suspension, which, unlike the hidden “softail” suspension, was a prominent part of the bike’s aesthetic. The FXD Super Glide came equipped with mid-mounted foot controls and a handlebar that placed the rider in an upright, neutral position, contributing to its reputation as a capable all-around cruiser.

While not designed as a sportbike, the Dyna was widely considered the best-handling “Big Twin” in the Harley-Davidson lineup of its time. The frame’s stiffness and conventional suspension geometry provided a responsive and confident ride, making it popular among riders who valued cornering ability as much as straight-line cruising.

Styling and Model Identity

The FXD Super Glide was the entry-point to the Dyna family, characterized by its straightforward, no-frills styling. It eschewed the heavy ornamentation of other models for a more classic and elemental look. Key features included a “Fat Bob” fuel tank with a console-mounted speedometer, a solo seat (though often equipped with a two-up seat), and chrome-finished components like the engine covers and staggered dual exhaust pipes. This minimalist approach made it an exceptionally popular platform for customization, serving as a blank canvas for owners to modify according to their personal tastes.
