Modern Harley-branded motorcycles fall into one of seven model families: Touring, Softail, Dyna, Sportster, Vrod, Street and LiveWire. These model families are distinguished by the frame, engine, suspension, and other characteristics.
Touring
Touring models use Big-Twin engines and large-diameter telescopic forks. All Touring designations begin with the letters FL, e.g., FLHR (Road King) and FLTR (Road Glide).
The touring family, also known as "dressers" or "baggers", includes Road King, Road Glide, Electra Glide and Street Glide models offered in various trims. The Road Kings have a "retro cruiser" appearance and are equipped with a large clear windshield. Road Kings are reminiscent of big-twin models from the 1940s and 1950s. Electra Glides can be identified by their full front fairings. Most Electra Glides sport a fork-mounted fairing referred to as the "Batwing" due to its unmistakable shape. The Road Glide and Road Glide Ultra Classic have a frame-mounted fairing, referred to as the "Sharknose". The Sharknose includes a unique, dual front headlight.
Touring models are distinguishable by their large saddlebags [140]], rear coil-over air suspension and are the only models to offer full fairings with radios and CBs. All touring models use the same frame, first introduced with a Shovelhead motor in 1980, and carried forward with only modest upgrades until 2009, when it was extensively redesigned. The frame is distinguished by the location of the steering head in front of the forks and was the first H-D frame to rubber mount the drivetrain to isolate the rider from the vibration of the big V-twin. The frame was modified for the 1993 model year when the oil tank went under the transmission and the battery was moved inboard from under the right saddlebag to under the seat. In 1997, the frame was again modified to allow for a larger battery under the seat and to lower seat height. In 2007, Harley-Davidson introduced the 96 cuin[141] Twin Cam 96 engine, as well the six-speed transmission to give the rider better speeds on the highway.
In 2006, Harley introduced the FLHX Street Glide, a bike designed by Willie G. Davidson to be his personal ride, to its touring line.[142]
In 2008, Harley added anti-lock braking systems and cruise control as a factory installed option on all touring models (standard on CVO and Anniversary models).[143] Also new for 2008 is the 6 usgal fuel tank for all touring models. 2008 also brought throttle-by-wire to all touring models.
For the 2009 model year, Harley-Davidson redesigned the entire touring range with several changes, including a new frame, new swingarm, a completely revised engine-mounting system, 17 in front wheels for all but the FLHRC Road King Classic, and a 2–1–2 exhaust. The changes result in greater load carrying capacity, better handling, a smoother engine, longer range and less exhaust heat transmitted to the rider and passenger.[144][145] Also released for the 2009 model year is the FLHTCUTG Tri-Glide Ultra Classic, the first three-wheeled Harley since the Servi-Car was discontinued in 1973. The model features a unique frame and a 103-cubic-inch (1,690 cc) engine exclusive to the trike.[146]
In 2014, Harley-Davidson released a redesign for specific touring bikes and called it "Project Rushmore".[147] Changes include a new 103CI High Output engine, one handed easy open saddlebags and compartments, a new Boom! Box Infotainment system with either 4.3-inch (10 cm) or 6.5-inch (16.5 cm) screens featuring touchscreen functionality [6.5-inch (16.5 cm) models only], Bluetooth (media and phone with approved compatible devices), available GPS and SiriusXM, Text-to-Speech functionality (with approved compatible devices) and USB connectivity with charging. Other features include ABS with Reflex linked brakes, improved styling, Halogen or LED lighting and upgraded passenger comfort.
Softail
These big-twin motorcycles capitalize on Harley's strong value on tradition. With the rear-wheel suspension hidden under the transmission, they are visually similar to the "hardtail" choppers popular in the 1960s and 1970s, as well as from their own earlier history. In keeping with that tradition, Harley offers Softail models with "Heritage" styling that incorporate design cues from throughout their history and used to offer "Springer" front ends on these Softail models from the factory.
Softail models utilize the big-twin engine (F) and the Softail chassis (ST).
- Softail models that use 21-inch (530 mm) Front Wheels have designations that begin with FX, e.g., FXSTB (Night Train), FXSTD (Deuce), and FXSTS (Springer).
- Softail models that use 16-inch (410 mm) Front Wheels have designations beginning with FL, e.g., FLSTF (Fat Boy), FLSTC (Heritage Softail Classic), FLSTN (Softail Deluxe) and FLS (Softail Slim).
- Softail models that use Springer forks with a 21 in wheel have designations that begin with FXSTS, e.g., FXSTS (Springer Softail) and FXSTSB (Bad Boy).
- Softail models that use Springer forks with a 16 in wheel have designations that begin with FLSTS, e.g., FLSTSC (Springer Classic) and FLSTSB (Cross Bones).
Dyna
Dyna-frame motorcycles were developed in the 1980s and early 1990s and debuted in the 1991 model year with the FXDB Sturgis offered in limited edition quantities. In 1992 the line continued with the limited edition FXDB Daytona and a production model FXD Super Glide. The new DYNA frame featured big-twin engines and traditional styling. They can be distinguished from the Softail by the traditional coil-over suspension that connects the swingarm to the frame, and from the Sportster by their larger engines. On these models, the transmission also houses the engine's oil reservoir.
Prior to 2006, Dyna models typically featured a narrow, XL-style 39mm front fork and front wheel, as well as footpegs [148]] which the manufacturer indicated with the letter "X" in the model designation. This lineup traditionally included the Super Glide (FXD), Super Glide Custom (FXDC), Street Bob (FXDB), and Low Rider (FXDL). One exception was the Wide Glide (FXDWG), which featured thicker 41mm forks and a narrow front wheel, but positioned the forks on wider triple-trees that give a beefier appearance. In 2008, the Dyna Fat Bob (FXDF) was introduced to the Dyna lineup, featuring aggressive styling like a new 2–1–2 exhaust, twin headlamps, a 180 mm rear tire, and, for the first time in the Dyna lineup, a 130 mm front tire. For the 2012 model year, the Dyna Switchback (FLD) became the first Dyna to break the tradition of having an FX model designation with floorboards, detachable painted hard saddlebags, touring windshield, headlight nacelle and a wide front tire with full fender. The new front end resembled the big-twin FL models from 1968 to 1971.
The Dyna family used the 88-cubic-inch (1,440 cc) twin cam from 1999 to 2006. In 2007, the displacement was increased to 96 cubic inches (1,570 cc) as the factory increased the stroke to 4.375 in. For the 2012 model year, the manufacturer began to offer Dyna models with the 103-cubic-inch (1,690 cc) upgrade. All Dyna models use a rubber-mounted engine to isolate engine vibration.
Sportster
Introduced in 1957, the Sportster family were conceived as racing motorcycles, and were popular on dirt and flat-track race courses through the 1960s and 1970s. Smaller and lighter than the other Harley models, contemporary Sportsters make use of 883 cc or 1,200 cc Evolution engines and, though often modified, remain similar in appearance to their racing ancestors.[150]
Up until the 2003 model year, the engine on the Sportster was rigidly mounted to the frame. The 2004 Sportster received a new frame accommodating a rubber-mounted engine. This made the bike heavier and reduced the available lean angle, while it reduced the amount of vibration transmitted to the frame and the rider, providing a smoother ride for rider and passenger.[151]
In the 2007 model year, Harley-Davidson celebrated the 50th anniversary of the Sportster and produced a limited edition called the XL50, of which only 2000 were made for sale worldwide. Each motorcycle was individually numbered and came in one of two colors, Mirage Pearl Orange or Vivid Black. Also in 2007, electronic fuel injection was introduced to the Sportster family, and the Nightster model was introduced in mid-year. In 2009, Harley-Davidson added the Iron 883 to the Sportster line, as part of the Dark Custom series. In the 2008 model year, Harley-Davidson released the XR1200 Sportster in Europe, Africa, and the Middle East. The XR1200 had an Evolution engine tuned to produce 91 bhp, four-piston dual front disc brakes, and an aluminum swing arm. Motorcyclist featured the XR1200 on the cover of its July 2008 issue and was generally positive about it in their "First Ride" story, in which Harley-Davidson was repeatedly asked to sell it in the United States.
VRSC
Introduced in 2001 and produced until 2017,[156] the VRSC muscle bike family bears little resemblance to Harley's more traditional lineup. Competing against Japanese and American muscle bikes in the upcoming muscle bike/power cruiser segment, the "V-Rod" makes use of the revolution engine that, for the first time in Harley history, incorporates overhead cams and liquid cooling. The V-Rod is visually distinctive, easily identified by the 60-degree V-Twin engine, the radiator and the hydroformed frame members that support the round-topped air cleaner cover. The VRSC platform was also used for factory drag-racing motorcycles.
In 2008, Harley added the anti-lock braking system as a factory-installed option on all VRSC models.[143] Harley also increased the displacement of the stock engine from 1130 to 1250 cc, which had only previously been available from Screamin' Eagle, and added a slipper clutch as standard equipment.
VRSC models include: VRSC models utilize the Revolution engine (VR), and the street versions are designated Street Custom (SC). After the VRSC prefix common to all street Revolution bikes, the next letter denotes the model, either A (base V-Rod: discontinued), AW (base V-Rod + W for Wide with a 240 mm rear tire), B (discontinued), D (Night Rod: discontinued), R (Street Rod: discontinued), SE and SEII (CVO Special Edition), or X (Special edition). Further differentiation within models are made with an additional letter, e.g., VRSCDX denotes the Night Rod Special.
VRXSE
The VRXSE V-Rod Destroyer is Harley-Davidson's production drag racing motorcycle, constructed to run the quarter mile in less than ten seconds. It is based on the same revolution engine that powers the VRSC line, but the VRXSE uses the Screamin' Eagle 1,300 cc "stroked" incarnation, featuring a 75 mm crankshaft, 105 mm Pistons, and 58 mm throttle bodies.
The V-Rod Destroyer is not a street-legal motorcycle. As such, it uses "X" instead of "SC" to denote a non-street bike. "SE" denotes a CVO Special Edition.
Street
The Street, Harley-Davidson's newest platform and their first all new platform in thirteen years, was designed to appeal to younger riders looking for a lighter bike at a cheaper price.[157] The Street 750 model was launched in India at the 2014 Indian Auto Expo, Delhi-NCR on February 5, 2014. The Street 750 weighs 218 kg and has a ground clearance of 144 mm giving it the lowest weight and the highest ground clearance of Harley-Davidson motorcycles currently available.[158]
The Street 750 uses an all-new, liquid-cooled, 60° V-twin engine called the Revolution X. In the Street 750, the engine displaces 749 cc and produces 65 Nm at 4,000 rpm. A six speed transmission is used.[158]
The Street 750 and the smaller-displacement Street 500 have been available since late 2014.[157] Street series motorcycles for the North American market will be built in Harley-Davidson's Kansas City, Missouri plant,[157]
LiveWire
Harley-Davidson's LiveWire, released in 2019, is their first electric vehicle. The high-voltage battery provides a minimum city range of 98 miles (158 km).[159] The LiveWire targets a different type of customer than their classic V-twin powered motorcycles.[160]
In March 2020, a Harley-Davidson LiveWire was used to break the 24-hour distance record for an electric motorcycle. The bike traveled a reported 1,723 km (1,079 miles) in 23 hours and 48 minutes. The LiveWire offers a Level 1 slow recharge, which uses a regular wall outlet to refill an empty battery overnight, or a quick Level 3 DC Fast Charge. The Fast Charge fills the battery most of the way in about 40 minutes. Swiss rider Michel von Tell used the Level 3 charging to make the 24-hour ride.[161]
In December 2021, the company announced that LiveWire was to be spun-off from parent Harley Davidson, set to go public in the first half of 2022 as a special-purpose acquisition company (SPAC) with the value estimated to be $1.77 billion.[162]
