2018 Harley-Davidson 115th Anniversary Touring Models — Milwaukee-Eight Limited-Edition FL Touring and Touring-Derived Anniversary Machines

The 2018 Harley-Davidson 115th Anniversary Touring models were not a separate engineering platform, but a carefully defined group of serialized factory editions built around Harley-Davidson’s then-new Milwaukee-Eight Touring generation. They sat at the intersection of modern FL touring equipment, anniversary collectibility, and the factory bagger market that had become central to Harley-Davidson’s North American identity.

Mechanically, these motorcycles belonged to the second model year of the Milwaukee-Eight Touring family, introduced for 2017 with four-valve cylinder heads, single-cam architecture, improved cooling strategies, revised suspension, and the touring chassis that had carried Harley’s long-distance FL line into the modern bagger era. The 115th Anniversary treatment mattered because it attached factory serialization, anniversary paint, special badging, and limited announced production to models that were already high-volume cultural fixtures: the Street Glide Special, Ultra Limited, Tri Glide Ultra, and CVO Limited.

Best Known For: serialized 115th Anniversary factory paint and trim on Milwaukee-Eight Touring models, combining modern Harley-Davidson long-distance hardware with limited-edition collector identity.

Quick Facts

The table below summarizes the 2018 115th Anniversary Touring group as an enthusiast reference. It treats the models as a family because the anniversary package was applied across more than one Touring or touring-derived platform rather than to a single model code.

The important point is that the anniversary designation does not replace the underlying model identity. A 115th Anniversary Street Glide Special remains an FLHXS Street Glide Special; a 115th Anniversary Ultra Limited remains an FLHTK Ultra Limited. Collectors therefore evaluate both halves of the machine: the correctness of the anniversary equipment and the condition of the underlying Milwaukee-Eight Touring platform.

Why It Matters

Harley-Davidson anniversary editions have long occupied a distinct place in the marque’s collecting culture. They are modern enough to be usable, yet they carry factory documentation and visual cues that separate them from standard-color production motorcycles. The 115th Anniversary Touring models are especially relevant because they arrived just after the Milwaukee-Eight engine replaced the Twin Cam in the Touring line.

That timing matters. By 2018, the Touring range had become the company’s principal expression of American heavyweight motorcycling: batwing fairings, sharknose Road Glide culture nearby, Tour-Paks, hard bags, infotainment, floorboards, big torque, and heavy long-distance machinery built for interstates rather than short café hops. The 115th Anniversary Touring models captured that moment in factory-special form.

They also reflect Harley-Davidson’s increasing understanding that collectors were not interested only in prewar singles, Knuckleheads, Panheads, or early Shovelheads. A modern limited FL, especially one with factory serialization and anniversary paint, could be bought new as a rider and preserved from the start as a collectible object. That dual identity is why these machines deserve their own page rather than being treated as simple color options.

Historical Context and Development Background

The 2018 model year found Harley-Davidson in a period of significant product change. The Milwaukee-Eight engine had been introduced in Touring models for 2017, bringing a four-valve-per-cylinder head design, more refined thermal management, a single camshaft, and a character deliberately tuned to retain the big Harley cadence while improving torque delivery and heat control compared with the outgoing Twin Cam Touring machines.

The company was also responding to a market in which factory baggers had become one of the most visible forms of American motorcycling. Street Glide and Road Glide culture had expanded well beyond traditional touring use, with custom bagger builders, audio systems, big-wheel conversions, paintwork, and performance engine upgrades influencing showroom demand. The Street Glide Special anniversary model therefore carried a different cultural charge than an anniversary Electra Glide from an earlier generation: it was a premium factory bagger as much as a touring motorcycle.

At the upper end, the Ultra Limited and CVO Limited represented Harley’s most equipment-rich two-wheel touring tradition. Full fairings, lower fairings on relevant models, hard luggage, passenger accommodations, and large-displacement V-twin torque made them the successors to decades of Electra Glide travel culture. The Tri Glide Ultra, while technically a trike rather than a two-wheel Touring model, shared enough touring equipment and customer purpose to belong naturally in discussions of the 115th Anniversary long-distance family.

Competitors in the same broad touring space included Honda’s Gold Wing, BMW’s K 1600 series, Indian’s Thunder Stroke touring models, and Yamaha’s transcontinental touring offerings. Harley-Davidson did not pursue those rivals by imitating their mechanical language. Instead, the Milwaukee-Eight Touring line defended the FL formula: a large-displacement, air- or Twin-Cooled pushrod V-twin in a steel chassis, with heavy touring equipment and a distinctly American cadence.

Engine and Drivetrain

The 115th Anniversary Touring models were unified by Milwaukee-Eight architecture, but not by a single engine specification. The Street Glide Special used the air-cooled Milwaukee-Eight 107. The Ultra Limited and Tri Glide Ultra used the Twin-Cooled Milwaukee-Eight 107, with liquid-cooled cylinder-head areas integrated into the touring package. The CVO Limited used the larger Twin-Cooled Milwaukee-Eight 117, the factory performance-displacement engine reserved for Custom Vehicle Operations models.

All used a 45-degree V-twin layout, four valves per cylinder, pushrods, hydraulic lifters, electronic sequential port fuel injection, and modern electronic ignition management. The single-cam Milwaukee-Eight layout was a sharp departure from the Twin Cam nameplate, although Harley deliberately preserved the visual and rhythmic identity expected of a Big Twin touring motorcycle. Lubrication is dry-sump, as is typical for Harley-Davidson Big Twin architecture.

The drivetrain remained familiar to FL riders: primary drive to a wet multi-plate clutch, 6-speed Cruise Drive transmission, and belt final drive. That continuity is part of the appeal. The Milwaukee-Eight changed the engine’s breathing, cooling, and refinement, but the rider still experienced the machine as a floorboard-equipped, heel-and-toe-shifted, belt-drive Harley tourer rather than as a clean-sheet sport-tourer.

Engine and Drivetrain Specifications

The following specifications are the core mechanical distinctions collectors and buyers should know when comparing 115th Anniversary Touring variants.

Harley-Davidson traditionally promoted torque rather than horsepower for these motorcycles, and factory horsepower figures were not the center of period specification sheets. For collector and restoration purposes, engine displacement, cooling type, and correct model association are more useful than aftermarket horsepower estimates.

Chassis, Suspension, and Braking

The two-wheel 115th Anniversary Touring models used Harley-Davidson’s steel Touring chassis with a rubber-mounted powertrain. That rubber mounting is central to the FL touring experience: it allows the large 45-degree V-twin to retain its low-speed pulse without transmitting the same level of continuous vibration to the rider at cruising speed.

The 2018 Touring generation used 49 mm dual bending valve front forks, a significant practical improvement over older damper-rod touring behavior. Rear suspension on the two-wheel Touring models used emulsion shock units with hand-adjustable preload on many Touring specifications. The Tri Glide Ultra naturally differs at the rear, using a touring-derived three-wheel chassis and rear axle arrangement rather than conventional motorcycle swingarm behavior.

Braking specification depended on model and market, particularly where ABS and linked braking equipment were concerned. Harley’s touring brake systems of this period commonly used multi-piston disc-brake hardware, and premium Touring models were often equipped with ABS and linked braking functions. A buyer should verify the actual equipment on the motorcycle rather than assuming every anniversary example in every market was identically configured.

Chassis and Equipment Reference

This table focuses on details that help distinguish the anniversary Touring models in the real world: fairing type, touring equipment, and the basic mechanical platform beneath the paint.

The weight figures are useful because they explain why these motorcycles should be judged by touring standards rather than by performance-cruiser standards. The Street Glide Special is the bagger of the group; the Ultra Limited and CVO Limited are fully dressed two-up tourers; the Tri Glide Ultra is a different kind of long-distance machine altogether.

Riding Experience and Mechanical Character

A 2018 115th Anniversary Touring model starts like a modern fuel-injected Harley rather than an old FLH. There is no carburetor tickling, choke ritual, or magneto drama; the ignition sequence, fuel pump prime, and starter engagement belong to the electronic age. Yet once the Milwaukee-Eight settles, the rider still gets the uneven, heavy-pulse character that defines the Big Twin touring line.

The Milwaukee-Eight 107 is smoother and more tractable than many late Twin Cam touring engines, particularly at low rpm and during roll-on acceleration. It pulls with the broad, low-speed authority expected of a large touring V-twin, but with noticeably cleaner response through electronic fuel injection and four-valve breathing. The 117 in the CVO Limited adds displacement and authority, especially noticeable when the motorcycle is loaded with passenger and luggage.

Control layout is conventional modern Harley touring practice: floorboards, hand clutch, foot shift, large touring switchgear, and substantial cockpit mass around the rider. The Street Glide Special has the leanest feel of the anniversary group, partly because it omits the fixed rear Tour-Pak and carries the visual language of the custom bagger. The Ultra Limited and CVO Limited feel more like full-dress touring motorcycles, with the rider seated inside a broader envelope of fairing, luggage, passenger equipment, and audio/navigation hardware.

The gearbox has the solid, deliberate engagement familiar to modern Harley big twins. Clutch feel is heavier than a middleweight motorcycle but appropriate to the torque and driveline mass involved. At low speed, these motorcycles remind the rider of their weight, especially during parking-lot maneuvers, cambered stops, and two-up loading. Once rolling, the Touring chassis is stable, planted, and best understood as a long-wheelbase road machine rather than a quick-steering back-road tool.

Braking is far better than on earlier FL generations, but mass remains mass. A rider coming from a Panhead, Shovelhead, or early Evolution Electra Glide would find the 2018 brake package powerful and controlled; a rider coming from a modern sport-tourer would still notice the considerable weight and conservative chassis geometry. That contrast is part of the machine’s identity.

Identification and Originality

Correct identification begins with the underlying model code. The anniversary package does not erase the FLHXS, FLHTK, FLHTCUTG, or FLHTKSE identity. A serious buyer should verify the VIN, model code documentation, factory option records where available, owner’s manual packet, delivery paperwork, and any certificate or serialized anniversary documentation that accompanied the motorcycle.

The most visible clues are the 115th Anniversary paint and badging. Harley-Davidson used a blue-and-black anniversary color treatment on these limited models, commonly identified with Legend Blue and Vivid Black in factory descriptions, with anniversary medallions or graphics and serialized identification. Collectors place a premium on motorcycles that retain their original painted tins, factory badging, correct console or emblem treatment, and unmodified anniversary trim.

Common originality issues are typical of modern Harley Touring ownership. Exhaust systems are frequently changed; intake kits and tuner installations are common; handlebars may be replaced with taller ape-hanger or touring bars; seats, windshields, audio components, lighting, and wheels are often altered. None of these changes is unusual, but for an anniversary collector, every deviation from delivery specification reduces the machine’s documentary clarity.

Reproduction or replacement painted parts deserve particular scrutiny. A standard Touring model can be dressed with anniversary-style parts, and a crashed anniversary machine can be repaired with replacement tins. The difference between a genuine, documented anniversary model and a visually converted standard model is central to value. Factory paperwork, VIN/model confirmation, serialized anniversary equipment, and credible ownership history matter more than a casual claim based on paint alone.

Model Code and Variant Breakdown

The 2018 anniversary Touring group is best understood by separating the underlying model code from the anniversary trim. The table below covers the key variants most often encountered by collectors and buyers researching the 115th Anniversary Touring editions.

Those announced quantities are important because they are often quoted in collector listings. They should not replace a physical inspection or documentation review, but they explain why certain variants, particularly the CVO Limited and Tri Glide Ultra, appear less frequently than standard 2018 Touring models.

Performance and Dimensional Specifications

Harley-Davidson’s period literature emphasized engine torque, touring equipment, comfort systems, infotainment, paint, and model positioning more than sport-style performance numbers. Factory 0–60 mph times, quarter-mile times, and top-speed claims are not useful identifiers for these motorcycles and should not be treated as collector-grade specifications.

Published running-order weights are more relevant. Harley-Davidson listed the 2018 Street Glide Special at 829 lb in running order, the Ultra Limited at 908 lb, the Tri Glide Ultra at 1,243 lb, and the CVO Limited at 944 lb. These numbers explain the riding character better than any unsupported acceleration claim: the Milwaukee-Eight delivers substantial torque, but it is working in large, fully equipped touring machinery.

Horsepower figures are commonly generated by chassis dyno testing or aftermarket discussion, but Harley-Davidson did not make horsepower the central factory specification for these models. For accurate comparison, use engine family, displacement, cooling type, torque rating in the relevant market literature, and final drive gearing rather than internet horsepower summaries.

Compared With Related Models

115th Anniversary Street Glide Special vs. Standard 2018 Street Glide Special

The mechanical foundation is substantially the same: Milwaukee-Eight 107, batwing fairing, hard bags, Touring chassis, and factory bagger stance. The anniversary version adds the limited paint and serialized 115th Anniversary treatment. For a rider, the distinction is visual and collectible; for a collector, it is a documentation and originality question.

115th Anniversary Ultra Limited vs. Street Glide Special

The Ultra Limited is the more traditional long-distance FL touring motorcycle, with Tour-Pak, passenger backrest, fuller touring equipment, and Twin-Cooled Milwaukee-Eight 107 specification. The Street Glide Special is the cleaner bagger form, lighter and visually lower, aimed at riders who wanted the fairing-and-bags look without the full touring rear furniture.

115th Anniversary CVO Limited vs. Ultra Limited

The CVO Limited is the factory flagship interpretation. Its Twin-Cooled Milwaukee-Eight 117, CVO trim, paint execution, and equipment level place it above the standard Ultra Limited in both specification and collector hierarchy. It is also the model most likely to be judged harshly for missing CVO-specific accessories, non-original audio equipment, altered exhaust, or incomplete documentation.

115th Anniversary Tri Glide Ultra vs. Two-Wheel Touring Models

The Tri Glide Ultra is not simply a Touring model with an extra wheel bolted on. Its three-wheel chassis, rear bodywork, reverse equipment, storage layout, and riding dynamics make it a distinct machine. Collectors and buyers should compare it with other Harley-Davidson factory trikes, not with two-wheel FLH models alone.

Restoration and Ownership Notes

Because these are modern Harley-Davidsons, routine service parts are far easier to source than for early FLs, Knuckleheads, Panheads, or AMF-era restorations. Mechanical support is broad, specialist knowledge is plentiful, and the Milwaukee-Eight platform is well understood by independent Harley shops as well as dealer technicians. The restoration challenge is not usually basic mechanical survival; it is preserving or returning the motorcycle to correct anniversary specification.

Milwaukee-Eight ownership requires attention to service history, oiling-system updates where applicable, cam chest condition on modified engines, and the quality of any tuning work. Many Touring models were fitted with exhausts, high-flow air cleaners, performance cams, and electronic tuners soon after delivery. A well-executed stage upgrade is not necessarily a problem for a rider, but an undocumented or poorly mapped engine can create heat, drivability, and warranty-history questions.

For the anniversary collector, paintwork is the difficult part. Factory anniversary tins and trim are not equivalent to ordinary replacement bodywork. A repainted tank or substituted saddlebag lid can be perfectly functional and still materially affect originality. Matching the finish, graphics, badging, serialized equipment, and model-specific trim is where a cosmetic restoration can become expensive.

Electrical and equipment checks matter on Ultra Limited, Tri Glide Ultra, and CVO Limited examples. Infotainment units, speakers, heated grips or seats where fitted, lighting accessories, luggage locks, Tour-Pak hardware, and trike-specific reverse systems should all be tested. These motorcycles are complex by Harley standards, and deferred small faults can add up quickly.

Buyer and Restoration Inspection Points

A proper inspection should confirm both the motorcycle and the anniversary identity. The following table is aimed at buyers, restorers, and collectors evaluating a real machine rather than browsing a specification sheet.

The best examples are not necessarily the lowest-mile machines, though low mileage often attracts collectors. The strongest candidates are documented, uncrashed, carefully stored, mechanically serviced, and complete with the anniversary-specific parts that cannot be recreated casually.

Collector and Market Relevance

The 2018 115th Anniversary Touring models occupy a different market position from antique Harley-Davidsons. They are not rare in the prewar sense, and they do not carry the hand-built mechanical archaeology of a Strap Tank single, Knucklehead, or early EL. Their value lies in factory-limited modern collectibility: serialized production, anniversary identity, premium model placement, and immediate usability.

Within the group, hierarchy generally follows specification and scarcity. The CVO Limited attracts attention because of its 117 cu in engine and CVO status. The Tri Glide Ultra appeals to a more specialized buyer but has limited announced production. The Ultra Limited is the most traditional touring collector choice, while the Street Glide Special connects directly with factory bagger culture and is often sought by riders who want the anniversary identity without the full-dress touring package.

Collectors typically value untouched paint, original exhaust and intake, complete documentation, low or carefully documented mileage, and preserved accessories. Modified examples can be excellent motorcycles, but they usually move from collector-grade territory into rider-grade or custom-bagger territory. That distinction is especially important with anniversary editions, where the factory condition is the point.

Cultural Relevance

The 115th Anniversary Touring models reflect Harley-Davidson’s long habit of turning corporate anniversaries into motorcycles that owners could buy, ride, and preserve. Earlier anniversary editions from the 75th, 90th, 95th, 100th, 105th, and 110th commemorations had already trained buyers to recognize special paint and badging as part of the Harley collecting vocabulary. The 115th models continued that practice in the Milwaukee-Eight era.

The Street Glide Special version also belongs to the modern bagger story. By 2018, the factory bagger was no longer simply a touring motorcycle with luggage; it had become a custom platform, club bike, audio platform, and long-distance statement machine. Harley-Davidson understood that culture well enough to give the anniversary package to the Street Glide Special rather than limiting it to conservative full-dress touring models.

The Ultra Limited and CVO Limited, by contrast, speak to the older Electra Glide tradition: big fairing, passenger comfort, luggage, and interstate work. The Tri Glide Ultra acknowledges another real part of Harley’s customer base, where long-distance riding, stability, age, injury, or preference could make a factory trike the logical touring machine. Together, the group gives a useful snapshot of what Harley-Davidson touring meant in the Milwaukee-Eight period.

FAQs

What years were the Harley-Davidson 115th Anniversary Touring models produced?

They were produced for the 2018 model year as part of Harley-Davidson’s 115th Anniversary limited-edition program. The anniversary trim was not a multi-year Touring sub-series.

Which 2018 Touring models received 115th Anniversary editions?

The principal Touring and touring-derived anniversary models were the FLHXS Street Glide Special, FLHTK Ultra Limited, FLHTCUTG Tri Glide Ultra, and FLHTKSE CVO Limited. Each retained its normal model identity beneath the anniversary paint and trim.

What engine did the 2018 115th Anniversary Street Glide Special use?

The 2018 FLHXS Street Glide Special 115th Anniversary used the air-cooled Milwaukee-Eight 107, a 107 cu in / 1,746 cc four-valve-per-cylinder pushrod V-twin with electronic fuel injection.

What makes the 115th Anniversary CVO Limited different?

The FLHTKSE CVO Limited 115th Anniversary used the Twin-Cooled Milwaukee-Eight 117, a 117 cu in / 1,923 cc engine, and carried CVO-level trim and equipment. It is generally the highest-specification motorcycle in the 2018 anniversary Touring group.

How can I identify a genuine 115th Anniversary Touring model?

Verify the VIN and model code, then confirm factory anniversary paint, badging, serialized anniversary details, documentation, and model-specific equipment. Paint alone is not enough, because standard Touring models can be visually converted or repaired with replacement parts.

Are modified 115th Anniversary Touring models less collectible?

Usually, yes. Exhaust, intake, tuner, handlebar, audio, wheel, and lighting changes are common on Harley Touring models, but collectors generally prefer complete, original, documented anniversary examples. Original take-off parts help if the motorcycle has been modified.

Are parts available for restoring a 2018 115th Anniversary Touring model?

Mechanical service parts are broadly available because these motorcycles are modern Milwaukee-Eight Touring machines. The difficult parts are anniversary-specific painted components, medallions, CVO equipment, and serialized trim, which are far more important to collector-grade restoration.

Collector Takeaway

The 2018 Harley-Davidson 115th Anniversary Touring models matter because they freeze the early Milwaukee-Eight Touring generation in factory-serialized form. They are not mechanically exotic in the old-racing sense, and they do not need to be. Their importance lies in being limited-edition versions of the motorcycles that defined Harley-Davidson’s heavyweight identity at the moment the company moved its Touring line from Twin Cam to Milwaukee-Eight power.

For the collector, the best example is not the loudest, most accessorized, or most heavily tuned bike. It is the one that still looks like Harley-Davidson intended in 2018: correct anniversary paint, correct trim, credible paperwork, unambiguous model identity, and mechanical condition good enough to tour rather than merely display. In that form, a 115th Anniversary Touring model is a useful modern collectible—one foot in the showroom, one foot in the marque archive.
