2009 Harley-Davidson FXDFSE CVO Fat Bob: Dyna CVO with the Screamin' Eagle Twin Cam 110

The 2009 Harley-Davidson FXDFSE CVO Fat Bob was the Custom Vehicle Operations version of the FXDF Dyna Fat Bob, a factory-built premium Dyna that put the 110-cubic-inch Screamin' Eagle Twin Cam into one of Harley-Davidson's most visually assertive late-Dyna chassis. It arrived when the Fat Bob identity was still new: twin headlamps, thick 16-inch rubber, bobbed fenders, dual front discs, and a stance deliberately tougher than the more traditional Super Glide and Low Rider vocabulary.

For collectors and informed Dyna buyers, the FXDFSE matters because it is not simply an accessory-laden FXDF. It is a factory CVO Dyna with the big 110-inch engine, CVO-specific finishes and equipment, and the short production-window significance that serious Harley-Davidson collectors tend to reward when originality is intact.

Best Known For: the 2009 FXDFSE CVO Fat Bob is best known as the first CVO Fat Bob, combining the Dyna FXDF platform with Harley-Davidson's factory Screamin' Eagle Twin Cam 110 powertrain and premium CVO treatment.

Quick Facts

The following table separates the 2009 FXDFSE CVO Fat Bob from the standard FXDF Dyna Fat Bob. It focuses on specifications and identity points that matter to buyers, restorers, and collectors rather than brochure adjectives.

The important point is the combination. The standard FXDF already had the Fat Bob visual signature, but the FXDFSE added the large-displacement CVO engine and factory-custom specification in a form that was available only briefly.

Why It Matters

The Dyna line has always occupied a particular place in Harley-Davidson culture: less touring-oriented than the FLH family, less heritage-bound than many Softails, and generally preferred by riders who wanted a rubber-mounted Big Twin in a chassis that felt more direct. By the late 2000s, the Dyna platform had developed a following among riders who valued engine tuning, brakes, suspension changes, mid-control conversions, and a less decorative attitude than the full-dress machines.

The Fat Bob pushed that Dyna identity in a bolder direction. Its twin headlamps and heavy front tire gave it a factory streetfighter-cruiser presence without abandoning Harley's air-cooled Big Twin architecture. The CVO version sharpened the proposition by adding the 110-inch Screamin' Eagle engine and premium finishes directly from the factory rather than leaving the owner to build a catalog special after delivery.

For collectors, the 2009 FXDFSE is significant because CVO Dynas were never high-volume motorcycles in the way regular-production Big Twins were. Condition, factory paint, original exhaust and intake equipment, correct documentation, and unmodified engine-management hardware are therefore more important than they would be on a heavily customized standard FXDF.

Historical Context and Development Background

Harley-Davidson's Custom Vehicle Operations program had, by the late 2000s, become the company's in-house answer to the high-end custom market. CVO motorcycles used limited-production paint schemes, larger-displacement Screamin' Eagle engines, upgraded trim, and carefully coordinated accessory packages while retaining factory warranty and manufacturer build quality. They were aimed at customers who wanted a finished premium custom rather than a blank canvas.

The 2009 FXDFSE arrived in difficult market conditions for the American motorcycle industry. The financial crisis had tightened discretionary spending, and the heavyweight cruiser segment was no longer riding the easy expansion of the previous decade. That context makes the FXDFSE interesting: it was not a conservative touring flagship but a premium Dyna with assertive styling and a 110-inch engine, aimed at the rider who wanted presence, torque, and factory exclusivity.

The Fat Bob's competitor landscape included Japanese and European power cruisers, factory-custom cruisers from other American-branded lines, and Harley's own Softail and Touring CVO machines. Against those alternatives, the FXDFSE's distinction was its Dyna chassis: rubber-mounted engine, exposed twin-shock rear suspension, and a more compact, mechanically honest appearance than the touring-based CVO motorcycles.

There was no racing or military program behind the FXDFSE. Its importance is commercial and cultural: it represents Harley-Davidson's factory-custom strategy applied to the Dyna platform at a moment when performance-minded Dyna ownership was becoming increasingly visible.

Engine and Drivetrain

The defining mechanical feature of the 2009 FXDFSE is the Screamin' Eagle Twin Cam 110. This is an air-cooled 45-degree V-twin with pushrod-operated overhead valves, two valves per cylinder, electronic fuel injection, and dry-sump lubrication. In Dyna installation it is rubber-mounted, which is central to the motorcycle's character: the engine can move at idle without transmitting the full shake directly into the rider, yet it remains visually exposed and mechanically dominant.

Harley-Davidson typically published torque rather than horsepower for these motorcycles. The 2009 FXDFSE is commonly listed with 110 ft-lb of torque at 3,000 rpm, while factory horsepower figures were not generally published in the same way. For that reason, horsepower claims should be treated cautiously unless tied to a specific dynamometer result from a known motorcycle.

Power passes through a primary chain to a multi-plate clutch, then through Harley-Davidson's 6-speed Cruise Drive transmission and belt final drive. The gearing and engine character suit the CVO Fat Bob's intended role: abundant low- and mid-range torque, relaxed highway rpm in sixth, and strong roll-on response without requiring the rider to chase revs.

Engine and Drivetrain Specifications

This table uses documented factory-type specifications and avoids unsupported performance figures. It is intended as a mechanical reference rather than a tuning guide.

In collector terms, the 110-inch engine is central to the FXDFSE's identity. A standard FXDF upgraded later with engine parts may be a stronger rider's motorcycle, but it is not the same as a factory-built FXDFSE unless the model code, documentation, and CVO equipment support it.

Chassis, Suspension, and Braking

The FXDFSE uses the Dyna chassis architecture, with the Big Twin rubber-mounted in a steel frame and the rear wheel controlled by twin shock absorbers. Compared with a Softail of the same period, the Dyna's exposed rear shocks and frame layout give it a more mechanically straightforward appearance. Compared with a Touring model, it is lighter, shorter, and more direct in feel, though without the long-distance equipment and wind protection of the FL platform.

The Fat Bob's visual identity is inseparable from its front end. The twin headlamps, broad fork presence, dual front discs, and wide 16-inch front tire give the motorcycle a blunt, planted stance. It was not a narrow, spoked-wheel retro cruiser; it was a factory muscle cruiser interpreted through Harley-Davidson's Dyna vocabulary.

Chassis and Equipment

The chassis table focuses on equipment that helps identify the motorcycle and understand its behavior. Exact component finishes and paint combinations should always be verified against factory literature for the specific motorcycle.

The brakes are an important part of the Fat Bob story. Dual front discs distinguished it from many cruisers whose styling wrote checks their single-disc front ends could not always cash. The FXDFSE is still a heavy air-cooled Big Twin, but its equipment specification was better aligned with the torque and mass of the motorcycle than a more lightly braked cruiser layout would have been.

Riding Experience and Mechanical Character

The 2009 FXDFSE is an electric-start, fuel-injected Big Twin, so there is no carburetor ritual, tickler, choke lever, or magneto routine to romanticize. The ritual is modern Harley: ignition on, run switch set, fuel pump primed, then the starter brings the large V-twin through a heavy compression cadence before it catches into the familiar uneven idle.

At idle the rubber-mounted Dyna engine moves with visible mass, a trait that gives these motorcycles much of their personality. Underway the worst of the shake recedes, but the rider is always aware of the engine's long-stroke pulse. The 110 does not feel like a rev-hungry motor; it feels broad, muscular, and insistent from low rpm, with the sort of roll-on torque that makes short-shifting natural.

The 6-speed Cruise Drive gearbox gives the motorcycle long-legged highway behavior compared with older five-speed Big Twins. Shift quality is substantial rather than delicate, with the mechanical engagement expected of a large Harley transmission. The clutch has enough weight to remind the rider that this is not a lightweight standard, but the controls are conventional and approachable for anyone familiar with late-model Harley-Davidson Big Twins.

The wide tires and substantial front end give the Fat Bob a planted sensation, especially in a straight line and through broad sweepers. At low speeds it feels broad-shouldered, not flickable. Braking is much better served by the dual front discs than by the single-disc arrangements used on many cruiser contemporaries, although mass and tire profile still define the stopping experience.

Identification and Originality

The most important identification point is the model code: the 2009 CVO Fat Bob is FXDFSE, while the standard Dyna Fat Bob is FXDF. The 2010 CVO continuation is FXDFSE2. Serious buyers should verify the model designation through factory paperwork, VIN-associated records, the original owner's manual packet where available, and dealer documentation rather than relying on accessories or seller descriptions.

Visually, the Fat Bob family is identified by the twin headlamp arrangement, broad front tire, bobbed fenders, muscular tank and rear fender treatment, and dual front disc brakes. The CVO version adds factory premium paint and trim, the Screamin' Eagle 110 engine, CVO-specific equipment, and a level of finish not present on the regular-production FXDF. Because many standard Dynas have been modified with Screamin' Eagle parts, paintwork, wheels, exhausts, and seats, the paperwork matters.

Originality issues often center on exhaust systems, air cleaners, electronic control modules or tuning devices, handlebars, seats, wheels, and paint. CVO motorcycles were frequently customized further despite leaving the factory already dressed. A modified FXDFSE may be a fine road motorcycle, but the collector premium generally follows factory paint, correct CVO parts, clean documentation, and reversible or documented changes.

Engine and frame number integrity should be treated seriously. The Dyna market includes many heavily used, performance-modified motorcycles, and the CVO Fat Bob's value depends on proving that the frame, engine, and documentation belong together. Replacement engines, insurance rebuilds, non-factory paint, missing CVO components, and unclear title history all require careful evaluation.

Model Code and Variant Breakdown

The FXDFSE is best understood within the short Dyna Fat Bob and CVO Fat Bob timeline. The following table highlights the model codes most likely to be confused by buyers researching a 2009 CVO Fat Bob.

The FXDFSE and FXDFSE2 are often grouped together in enthusiast discussion as the CVO Fat Bob pair. For a collector, however, the year and code are not interchangeable. Paint schemes, equipment details, documentation, and market interest can differ between 2009 and 2010 examples.

Performance and Dimensional Specifications

Harley-Davidson factory material for this period emphasized torque output rather than horsepower, and the 2009 FXDFSE is commonly listed at 110 ft-lb at 3,000 rpm. Factory horsepower was not published in the same consistent manner, so claimed horsepower figures should be treated as dynamometer-specific rather than universal.

Commonly listed factory dimensional data includes a 5.0-gallon fuel capacity, 130/90B16 front tire, 180/70B16 rear tire, and running-order weight around 703 lb. Figures such as 0-60 mph, quarter-mile time, and top speed vary by test conditions, rider, state of tune, and source; they are not essential to identifying or authenticating the motorcycle and should not be used as collector-grade specifications.

Compared With Related Models

FXDFSE CVO Fat Bob vs. Standard FXDF Dyna Fat Bob

The standard FXDF supplies the same basic Dyna Fat Bob shape: twin headlamps, chunky tires, exposed shocks, dual front discs, and the factory bobber-muscle stance. The FXDFSE adds the factory 110-inch CVO engine and the CVO finish level. A modified standard FXDF can be made faster or more personal, but it will not carry the same factory CVO identity unless the original model code and documentation support it.

FXDFSE 2009 vs. FXDFSE2 2010

The FXDFSE2 is the second-year CVO Fat Bob and is mechanically close in broad concept: Dyna chassis, Screamin' Eagle Twin Cam 110, premium CVO equipment. The differences are chiefly year-specific trim, color, and detail specification. Buyers should avoid assuming a 2009 part or paint detail automatically applies to a 2010 motorcycle.

Dyna CVO Fat Bob vs. CVO Touring Models

CVO Touring motorcycles of the same era offered wind protection, luggage, audio equipment, and long-distance comfort. The FXDFSE is a more elemental machine: less equipment, less mass, more exposed mechanical identity, and a stronger connection to the Dyna performance-cruiser audience. It is not the logical choice for two-up cross-country touring, but it is the more visually aggressive and mechanically compact CVO.

Dyna Fat Bob vs. 2018-on Softail Fat Bob

The 2018-on Fat Bob carried the name into the Milwaukee-Eight Softail generation, but it is not a Dyna. The later motorcycle uses the redesigned Softail chassis with hidden rear suspension and a different engine family. Collectors looking specifically for Dyna character should not treat the Softail FXFB or FXFBS as a direct substitute for an FXDFSE.

Restoration and Ownership Notes

Restoring a 2009 FXDFSE is less about fabricating impossible parts and more about returning a modified CVO to correct specification. Mechanical parts support for Twin Cam Harley-Davidsons is strong, and specialist knowledge is widely available. The harder pieces are usually cosmetic: original CVO paintwork, year-specific trim, correct exhaust and intake components, proper wheels, badges, seats, and small finish details.

The Twin Cam 110 deserves a careful pre-purchase inspection. Heat management, tuning quality, cam-chain system condition, compensator behavior, oil leaks, clutch wear, and evidence of aggressive engine work all matter. A motorcycle with aftermarket cams, exhaust, tuner, and air cleaner is not automatically a problem, but the quality of the work and the availability of original parts will affect both usability and collector value.

Documentation is unusually important on CVO models. Original bill of sale, factory literature, service records, CVO-related paperwork, stock parts retained by previous owners, and clear title history all help distinguish a genuine, well-kept FXDFSE from a standard FXDF dressed to resemble one. Paint authenticity should be inspected carefully because CVO finishes are a major part of the motorcycle's identity.

Buyer and Restoration Inspection Points

A good FXDFSE inspection should combine Harley-Davidson Big Twin mechanical sense with CVO-specific originality awareness. The following points are the ones that tend to separate a desirable collector-grade example from an expensive cosmetic project.

The best examples are not necessarily the lowest-mile motorcycles; they are the ones with coherent history. A well-serviced FXDFSE with original parts retained can be preferable to a low-mile bike that has been heavily altered and poorly documented.

Collector and Market Relevance

The FXDFSE sits in a specific collector lane: modern Harley-Davidson CVO, late Twin Cam, Dyna chassis, and first-year CVO Fat Bob. It does not have racing provenance, military history, or prewar scarcity. Its appeal comes from factory specification, limited-production status, mechanical desirability, and the growing recognition of Dyna models as culturally important Harley-Davidsons rather than merely used cruisers.

Collectors typically value original paint, correct CVO equipment, low or well-documented mileage, clean ownership history, unmodified engine-management hardware, and retained factory take-off parts. Modified examples may be more enjoyable for some riders, especially if fitted with quality suspension, exhaust, and tuning, but the market usually distinguishes between tasteful rider upgrades and irreversible loss of CVO originality.

Exact production numbers for the FXDFSE are not consistently cited in general factory-reference material, so unsupported claims should be treated cautiously. The more defensible statement is that CVO models were limited-production premium motorcycles and the Dyna CVO Fat Bob appeared only for the 2009 and 2010 model years as FXDFSE and FXDFSE2.

Cultural Relevance

The FXDFSE belongs to the period when Harley-Davidson was refining the factory custom as a complete product rather than a parts-counter exercise. It offered a high-specification machine with warranty, factory paint, big displacement, and a cohesive identity. That mattered because many customers wanted a custom look and stronger engine without managing a full aftermarket build.

The Dyna platform later became deeply associated with performance-oriented Harley culture: club-style builds, suspension upgrades, fairings, mid controls, engine work, and serious road use. The FXDFSE predates some of that broader cultural visibility, but it fits the same underlying idea better than many Softail customs of the era: exposed shocks, a real Dyna frame, dual discs, and a motor that responds to being ridden rather than merely admired.

Its cultural role is not cinematic mythology or racing laurels. It is the factory-built premium Dyna at a moment when Harley-Davidson still offered the Dyna as a distinct chassis family and before the name was folded into the later Softail platform.

FAQs

What years was the Harley-Davidson FXDFSE CVO Fat Bob produced?

The FXDFSE model code applies to the 2009 CVO Fat Bob. Harley-Davidson continued the CVO Fat Bob concept for 2010 as the FXDFSE2. The regular FXDF Dyna Fat Bob was introduced for 2008 and remained part of the Dyna line through the 2017 model year.

What engine is in the 2009 FXDFSE CVO Fat Bob?

The 2009 FXDFSE uses the Screamin' Eagle Twin Cam 110, an air-cooled 45-degree V-twin with pushrod-operated overhead valves and electronic fuel injection. Displacement is 110 cubic inches, or 1802 cc.

How is the FXDFSE different from a standard FXDF Fat Bob?

The standard FXDF is the regular-production Dyna Fat Bob. The FXDFSE is the CVO version, with the factory 110-inch Screamin' Eagle engine, CVO paint and trim, premium equipment, and limited-production status. Accessories alone do not make a standard FXDF into an FXDFSE.

Did Harley-Davidson publish horsepower for the 2009 CVO Fat Bob?

Harley-Davidson generally emphasized torque rather than horsepower for these models. The 2009 FXDFSE is commonly listed at 110 ft-lb of torque at 3,000 rpm. Horsepower figures usually come from independent dynamometer testing and vary with state of tune.

Is the 2009 FXDFSE a Dyna or a Softail?

It is a Dyna. The FXDFSE uses the Dyna chassis with rubber-mounted Big Twin engine and exposed twin rear shocks. The later 2018-on Fat Bob models moved to the redesigned Softail platform and are not Dyna motorcycles.

What should buyers check first on a used FXDFSE?

Confirm that the motorcycle is genuinely an FXDFSE through paperwork and title records, then inspect CVO paint authenticity, engine condition, tuning modifications, exhaust and intake changes, primary-drive behavior, and whether original CVO parts are included. Documentation is especially valuable on CVO models.

Is the 2009 CVO Fat Bob collectible?

Yes, within the modern Harley-Davidson collector field. Its appeal rests on being a first-year CVO Fat Bob, a Dyna-based CVO, and a factory 110-inch Screamin' Eagle motorcycle. Collector strength depends heavily on originality, documentation, condition, and preservation of CVO-specific equipment.

Collector Takeaway

The 2009 Harley-Davidson FXDFSE CVO Fat Bob matters because it captures a short-lived combination Harley-Davidson never repeated in exactly the same way: Dyna chassis, Fat Bob twin-headlamp attitude, factory CVO finish, and the 110-inch Screamin' Eagle Twin Cam. It is neither an old-world heritage piece nor a touring flagship. Its importance is sharper than that: it is a factory-built premium Dyna from the moment just before the Dyna platform became one of the most culturally charged Harley-Davidson chassis of its era.

The best FXDFSE examples will be the ones that still look and document like CVO motorcycles, not merely like modified Fat Bobs. Find one with original paint, correct equipment, sound mechanical history, and restrained ownership, and it becomes more than a muscular late-model cruiser. It becomes a reference point for the factory-custom Dyna: big engine, short production window, unmistakable stance, and enough mechanical honesty to keep serious Harley people interested.
