2023 Harley-Davidson Tri Glide Ultra 120th Anniversary — FLHTCUTG Twin-Cooled Milwaukee-Eight 114 Factory Touring Trike
The 2023 Harley-Davidson Tri Glide Ultra 120th Anniversary was not merely a color-and-badge exercise on an ordinary three-wheeler. It was Harley-Davidson’s fully dressed factory trike, built on the FLHTCUTG Tri Glide Ultra platform, fitted with the Twin-Cooled Milwaukee-Eight 114 engine and marked as part of the company’s 120th Anniversary model program. In Harley-Davidson terms, it sits at the intersection of modern touring engineering, factory-built three-wheel accessibility, and anniversary-edition collectibility.
The Tri Glide Ultra itself had already become the Motor Company’s definitive luxury trike: a batwing-faired, Tour-Pak-equipped, reverse-assisted touring machine aimed at riders who wanted Harley’s long-distance touring vocabulary without balancing a two-wheeled heavyweight at walking pace. The 120th Anniversary version added serialized commemorative identity, Heirloom Red Fade paint, anniversary trim, and a place within one of Harley-Davidson’s broadest modern celebration-year lineups.
Best Known For: The 2023 Tri Glide Ultra 120th Anniversary is best known as Harley-Davidson’s serialized 120th Anniversary factory touring trike, combining the FLHTCUTG Ultra touring package with the Twin-Cooled Milwaukee-Eight 114 and limited-edition Heirloom Red Fade anniversary presentation.
Quick Facts
The table below summarizes the reference points that matter most when identifying or evaluating a 2023 Tri Glide Ultra 120th Anniversary. It is a modern model, so factory specifications are comparatively well documented; horsepower is omitted because Harley-Davidson did not consistently publish a factory horsepower figure for this model in U.S. specifications.

Why It Matters
The Tri Glide Ultra 120th Anniversary matters because it represents a particular chapter in Harley-Davidson touring history: the normalization of the factory trike as a premium touring motorcycle rather than an aftermarket accommodation. Harley had sold Servi-Car utility trikes for decades in the 20th century, but the modern Tri Glide Ultra served a different audience. It was not a delivery vehicle or police utility machine; it was a full-featured, long-range touring platform built for riders who wanted the Harley touring experience with three-wheel stability.
The 2023 anniversary edition adds a collector layer to that practical significance. Harley-Davidson anniversary models have long attracted marque loyalists because they freeze a production-year identity into paint, trim, serialization, and factory paperwork. For the Tri Glide Ultra, the 120th Anniversary package is especially relevant because three-wheel Harley touring has become its own subculture within the broader Touring family, with owners placing high value on originality, low mileage, and complete documentation.
Historical Context and Development Background
Harley-Davidson introduced the modern Tri Glide Ultra Classic for the 2009 model year, giving the company a factory-built trike in the touring catalog after many years in which three-wheel Harleys were either utility-oriented historical machines or aftermarket conversions. By the time the 2023 Tri Glide Ultra 120th Anniversary arrived, the model had evolved into an established part of the lineup, sharing much of its identity with Harley’s large touring motorcycles while using a dedicated rear structure, two rear wheels, reverse assistance, and trike-specific setup.
The 2023 model year was significant for Harley-Davidson because it marked the company’s 120th anniversary. The factory commemorative motorcycles used special paint and badging rather than deep mechanical redesign, which is precisely why correct identification matters. The mechanical basis of the Tri Glide Ultra 120th Anniversary remained the contemporary FLHTCUTG: Twin-Cooled Milwaukee-Eight 114 power, six-speed transmission, touring fairing, infotainment, luggage, passenger accommodations, and integrated three-wheel chassis.
Its competitor landscape was not the same as that of a conventional touring motorcycle. A buyer might cross-shop a two-wheel Ultra Limited, a Can-Am Spyder or Ryker, a Gold Wing trike conversion, or another Harley trike such as the Freewheeler or Road Glide 3. The Tri Glide Ultra’s distinction was that it delivered the most traditional Harley touring presentation of the group: batwing fairing, floorboards, Tour-Pak, large rear trunk, upright passenger backrest, and the pulse of a big pushrod V-twin.
Engine and Drivetrain
The 120th Anniversary Tri Glide Ultra used Harley-Davidson’s Twin-Cooled Milwaukee-Eight 114 engine. This is the 1,868 cc version of the Milwaukee-Eight Big Twin, a 45-degree pushrod V-twin with four valves per cylinder and dual spark plugs. In Tri Glide Ultra form, it used liquid-cooled cylinder heads in addition to the air/oil cooling associated with the Milwaukee-Eight touring platform.
Fueling was by Electronic Sequential Port Fuel Injection. Ignition was electronic, and lubrication followed Harley-Davidson’s modern dry-sump Big Twin practice. The clutch and primary drive remained conventional Harley touring architecture in concept: a wet multi-plate clutch, chain primary drive, six-speed Cruise Drive gearbox, and belt final drive. The factory electric reverse system is an important part of the trike package and should be treated as a core feature, not a convenience accessory.
Engine and Drivetrain Specifications
These are the mechanical figures most useful to an owner, restorer, or buyer evaluating the motorcycle against related 2023 Harley-Davidson touring models.
| Item | 2023 Tri Glide Ultra 120th Anniversary |
|---|---|
| Engine | Twin-Cooled Milwaukee-Eight 114 |
| Configuration | 45-degree V-twin, pushrod-operated overhead valves, four valves per cylinder |
| Displacement | 114 cu in / 1,868 cc |
| Bore x stroke | 4.016 in x 4.5 in |
| Compression ratio | 10.5:1 |
| Fuel system | Electronic Sequential Port Fuel Injection |
| Factory torque rating | 121 lb-ft at 3,250 rpm |
| Transmission | 6-speed Cruise Drive |
| Primary drive | Chain |
| Final drive | Belt |
| Reverse | Factory electric reverse |
The important mechanical distinction is the Twin-Cooled 114 specification. A Freewheeler of the same period used Milwaukee-Eight power as well, but the Tri Glide Ultra’s full touring bodywork and lower fairings align it more closely with Harley’s premium touring machines than with the stripped-down trike models.
Chassis, Suspension, and Braking
The Tri Glide Ultra was engineered as a three-wheeler from the factory, not as a dealer-installed rear-end conversion on a two-wheel touring bike. That distinction affects structure, braking, reverse integration, rear bodywork, luggage layout, and service procedures. The result is a motorcycle that uses familiar Harley touring ergonomics forward of the rider while behaving very differently from a two-wheel FLH once the road begins to turn.
At the front, the Tri Glide Ultra used a 49 mm fork consistent with Harley’s touring architecture of the period. At the rear, the trike-specific suspension and axle package carried the twin rear automotive-type tires and the large rear trunk body. Braking was handled by Harley’s linked Brembo system with ABS, with a parking brake fitted as part of the trike equipment.
Chassis and Equipment Specifications
The following table focuses on equipment that affects identification, operation, and maintenance rather than subjective comfort claims.
| Item | Specification |
|---|---|
| Front suspension | 49 mm fork |
| Rear suspension | Trike-specific rear suspension with adjustable rear shocks |
| Front tire | MT90B16 72H |
| Rear tires | P205/65R15 |
| Braking system | Linked Brembo brakes with ABS |
| Parking brake | Standard trike equipment |
| Fuel capacity | 6.0 gal |
| Running order weight | 1,243 lb |
| As-shipped weight | 1,204 lb |
| Wheelbase | 65.7 in |
| Overall length | 105.1 in |
Those figures explain much of the motorcycle’s character. It is heavy even by full-dress touring standards, but the weight is carried across three contact patches and supported by reverse assistance. It is not a lightweight answer to touring; it is a stability-first answer to heavyweight touring.
Riding Experience and Mechanical Character
The Tri Glide Ultra 120th Anniversary starts like a modern Harley touring machine: key fob present, electronic fuel injection primed, starter engaged, and the Twin-Cooled Milwaukee-Eight settling into the broad, familiar cadence of a large 45-degree V-twin. There is no carburetor ritual, no manual spark control, no choke dance. The mechanical theatre comes from mass, pulse, exhaust cadence, and the distinct low-speed authority of a large-displacement pushrod engine.
From the saddle, the first surprise for a two-wheel touring rider is steering. A trike does not countersteer and lean into a corner in the familiar motorcycle sense; it is steered. At parking-lot speed the wide rear track gives confidence, while the electric reverse is essential rather than ornamental when dealing with grade, gravel, or tight garage space.
The Milwaukee-Eight 114 is well suited to the assignment because the trike asks for torque rather than revs. The throttle response is clean, the engine works from low rpm without drama, and the six-speed Cruise Drive gearbox suits open-road touring. Clutch effort and shift action are recognizably modern Harley touring rather than vintage Harley agricultural, though the driveline still carries the deliberate, mechanical engagement that longtime FL riders expect.
Braking has to be understood in trike terms. The linked Brembo system and ABS give the machine a level of integrated control far beyond older heavyweight touring motorcycles, but physics still governs a 1,200-plus-pound touring trike. The rider feels mass under braking and must plan with the machine’s width, rear grip, and load in mind.
On period roads, meaning modern interstates, secondary highways, and long-distance touring routes, the Tri Glide Ultra’s strength is composure. It is not a canyon tool and was never meant to be. Its purpose is steady two-up travel, luggage capacity, weather protection, passenger security, and the ability to continue touring when a conventional heavyweight two-wheeler no longer suits the rider.
Identification and Originality
Correct identification begins with the model code and documentation. The Tri Glide Ultra is the FLHTCUTG; the 120th Anniversary edition should be supported by factory paperwork, VIN documentation, dealer invoice or window sticker when available, owner’s manual materials, anniversary badging, and the correct paint and trim package. Collectors should not rely on paint alone, because body panels can be replaced or refinished.
The defining visual feature is the 120th Anniversary treatment. Factory anniversary models used Heirloom Red Fade paint with anniversary-specific badging and trim. On a Tri Glide Ultra, the paint presentation includes the large touring surfaces that make incorrect repainting or panel replacement easier to spot: front fender, batwing fairing, tank, side covers, Tour-Pak, and rear trike bodywork must all be examined for consistency of color, striping, finish quality, and factory-correct anniversary identifiers.
The equipment package should align with a Tri Glide Ultra, not a Freewheeler or Road Glide 3. A correct example has the batwing fairing, full touring passenger accommodations, Tour-Pak, rear trunk body, infotainment system, floorboards, fairing lowers associated with the Twin-Cooled setup, linked ABS braking, parking brake, and factory reverse. Missing or substituted components can be expensive because the motorcycle’s value depends heavily on complete factory presentation.
Modern Harley-Davidson identification is documentation-driven. Unlike early motorcycles where exposed engine architecture, belt drive, atmospheric intake valves, strap-mounted tanks, or paint-striping conventions define authenticity, this machine is verified through VIN records, model-code documentation, electronic service history, factory build configuration, and the physical presence of the anniversary package. For collector purposes, a clean title, original purchase documentation, manuals, keys and fobs, and service records matter more than folklore.
Model Code and Variant Breakdown
The 120th Anniversary Tri Glide Ultra should be understood as a specific edition within the Tri Glide Ultra line rather than as a separate mechanical platform. The model-code table below separates the relevant 2023 Tri Glide Ultra variants from nearby Harley trikes that are often confused with it.
| Model / Code | Years | Engine / Displacement | Purpose | Key Difference |
|---|---|---|---|---|
| Tri Glide Ultra / FLHTCUTG | 2023 model year | Twin-Cooled Milwaukee-Eight 114 / 1,868 cc | Full-dress factory touring trike | Standard Tri Glide Ultra specification without 120th Anniversary paint and serialization |
| Tri Glide Ultra 120th Anniversary / FLHTCUTG | 2023 model year | Twin-Cooled Milwaukee-Eight 114 / 1,868 cc | Commemorative full-dress factory touring trike | Serialized 120th Anniversary edition with Heirloom Red Fade paint and anniversary badging |
| Freewheeler / FLRT | Related 2023 trike model | Milwaukee-Eight 114 / 1,868 cc | Stripped-down cruiser-style factory trike | No Ultra touring fairing or Tour-Pak; different styling and equipment brief |
| Road Glide 3 / FLTRT | Related 2023 trike model | Milwaukee-Eight 114 / 1,868 cc | Factory trike with frame-mounted sharknose fairing | Road Glide-style fairing and different touring presentation from the batwing Tri Glide Ultra |
The table highlights the central point for collectors: the anniversary Tri Glide is mechanically close to the standard 2023 Tri Glide Ultra, but the edition-specific identity is the reason it is collected differently.
Performance and Dimensional Specifications
Harley-Davidson’s factory literature emphasized torque rather than horsepower, and a factory horsepower figure was not consistently published for this model in U.S. specifications. For a heavy touring trike, the published torque figure is more meaningful anyway, because low-speed pull, loaded touring response, and relaxed highway operation are the design priorities.
The factory-listed torque rating for the 2023 Tri Glide Ultra platform was 121 lb-ft at 3,250 rpm. Running order weight was listed at 1,243 lb, with as-shipped weight at 1,204 lb. Overall length was listed at 105.1 in, wheelbase at 65.7 in, and fuel capacity at 6.0 gallons. Period road-test acceleration figures vary by rider, load, testing method, and market source, so they are not useful collector-reference numbers for this page.
Compared With Related Models
Tri Glide Ultra 120th Anniversary vs Standard 2023 Tri Glide Ultra
Mechanically, the anniversary model is fundamentally a 2023 Tri Glide Ultra. The difference is collector presentation: Heirloom Red Fade paint, anniversary badging, serialization, and the documentation trail that proves it left the factory as a 120th Anniversary motorcycle. A standard Tri Glide Ultra may be the better choice for high-mile touring use; the anniversary model is more sensitive to originality and cosmetic preservation.
Tri Glide Ultra vs Freewheeler
The Freewheeler is the more stripped-down Harley factory trike, aimed at riders who want a cruiser stance and less touring bodywork. The Tri Glide Ultra is heavier, more protective, more passenger-oriented, and more luggage-focused. The buyer confusion is common because both are factory Harley trikes, but their missions are quite different.
Tri Glide Ultra vs Road Glide 3
The Road Glide 3 brought the frame-mounted sharknose fairing vocabulary into Harley’s three-wheel line. The Tri Glide Ultra retained the batwing-fairing FLH identity and the more traditional Ultra touring arrangement. Riders who prefer the fixed-fairing feel of a Road Glide may gravitate toward the FLTRT; collectors focused on anniversary trim and the classic Ultra silhouette look to the FLHTCUTG 120th Anniversary.
Tri Glide Ultra vs Ultra Limited
The Ultra Limited is the two-wheel touring relative: similar luxury-touring purpose, similar Harley touring equipment language, and comparable long-distance intent, but a completely different riding experience. The Tri Glide Ultra trades lean-angle behavior and two-wheel dynamics for three-wheel stability, reverse assistance, and reduced balancing demands at stops. That trade is exactly why the model exists.
Restoration and Ownership Notes
For a modern Harley trike, restoration is less about finding unobtainable castings and more about preserving the correct configuration. Paint and bodywork are central. Anniversary-specific body panels, striping, badges, and serialized identifiers are far more important than bolt-on chrome accessories, because the collector value rests on the motorcycle being recognizably and provably a factory 120th Anniversary example.
Mechanical service should follow Harley-Davidson factory intervals and use the correct fluids and procedures for the Milwaukee-Eight engine, primary case, transmission, cooling system components associated with the Twin-Cooled heads, brake system, reverse system, and rear axle assembly. The trike rear structure adds inspection areas that a two-wheel touring buyer may overlook: rear tire condition, axle seals, rear suspension condition, parking brake adjustment, trunk sealing, body-panel alignment, and evidence of curb or collision damage.
Electronics matter. The infotainment system, security system, ABS, linked braking hardware, reverse control, lighting, and charging system should all function correctly. A neglected modern touring Harley can become expensive not because parts are impossible to find, but because diagnostic time, bodywork, painted components, and electronic modules are costly relative to ordinary service parts.
Buyer and Restoration Inspection Points
A proper inspection of a 2023 Tri Glide Ultra 120th Anniversary should treat the motorcycle as both a touring machine and a limited-edition collector item. The following checklist focuses on the areas that materially affect authenticity, usability, and long-term value.
| Area | What to Check | Why It Matters |
|---|---|---|
| Model documentation | Confirm FLHTCUTG identity through title, VIN paperwork, dealer documents, and factory records where available | The anniversary trike’s value depends on documented factory identity, not simply appearance |
| 120th Anniversary equipment | Verify Heirloom Red Fade paint, anniversary badging, serialization, and matching trim across all major body panels | Replacement panels or repaints can reduce collector desirability if they disturb the factory anniversary presentation |
| Paint and bodywork | Inspect fairing, tank, fenders, Tour-Pak, rear trunk body, hinges, latches, and panel alignment | Trike bodywork is expensive, and anniversary paint is difficult to duplicate convincingly |
| Reverse system | Test factory electric reverse on level ground and on a mild incline within normal operating limits | Reverse is essential equipment on a heavy touring trike and can be costly to diagnose if neglected |
| Rear axle and suspension | Check for leaks, abnormal tire wear, shock condition, curb damage, and driveline noise | The trike rear assembly carries the machine’s distinctive load and is often overlooked by buyers used to two-wheel Harleys |
| Brakes and parking brake | Confirm linked brake operation, ABS warning-light behavior, rotor condition, pad wear, and parking brake adjustment | A heavy touring trike relies heavily on properly functioning integrated brakes |
| Twin-Cooled system | Inspect radiator areas in the lowers, coolant condition, hoses, fans, and signs of seepage | The Tri Glide Ultra uses Twin-Cooled cylinder heads, so cooling-system neglect is a real service issue |
| Electronics and infotainment | Test display, audio, lighting, security fobs, charging output, switches, and accessory circuits | Modern touring electronics affect both usability and repair cost |
| Service history | Look for documented engine, primary, transmission, brake-fluid, coolant, and tire service | A low-mile anniversary trike still needs time-based maintenance, not just mileage-based attention |
| Accessories and modifications | Identify non-factory exhausts, tuners, lighting, chrome additions, luggage changes, and comfort accessories | Touring accessories are common, but irreversible changes can hurt originality on a serialized anniversary model |
The best examples are the ones that combine collector documentation with genuine mechanical readiness. A trike that has been polished but not serviced is not as attractive as one with complete records, correct trim, and fully functioning touring systems.
Collector and Market Relevance
The Tri Glide Ultra 120th Anniversary occupies a different collector lane from early Harley singles, Knuckleheads, Panheads, XR race bikes, or AMF-era oddities. Its significance is modern, commemorative, and ownership-history driven. Collectors look for low mileage, original paint, unmodified equipment, complete anniversary documentation, and clear proof that the motorcycle was built as a 120th Anniversary edition.
Exact long-term market behavior depends on condition, mileage, originality, documentation, and buyer appetite for modern Harley commemorative models. It should not be evaluated like a scarce prewar machine with hand-built survival history, but neither should it be dismissed as ordinary production stock. Factory anniversary Harleys have an established following, and the trike version appeals to a specific subset of collectors who value usability as much as display presence.
Rarity should be described carefully. Harley-Davidson commonly listed the 2023 Tri Glide Ultra 120th Anniversary as a limited, serialized model, with the anniversary trike generally cited as limited to 1,100 units. For purchase evaluation, the individual motorcycle’s serialization, documents, and condition matter more than the production number alone.
Cultural Relevance
The Tri Glide Ultra is part of Harley-Davidson’s broader touring culture rather than its racing culture. It has no factory racing legacy and no military role comparable to wartime WLA models or the earlier Servi-Car’s utility history. Its importance lies in keeping riders in the Harley touring world when weight, balance, passenger needs, or physical limitations make a two-wheel Ultra less suitable.
That role is culturally significant. Within Harley owner groups and touring communities, the factory trike allowed riders to continue long-distance travel, rallies, two-up touring, and club participation without moving away from the Harley-Davidson platform. The 120th Anniversary edition adds the ceremonial layer: a rally-year, marque-loyalty motorcycle built to be recognized immediately as part of Harley’s 1903–2023 celebration.
