The Piaggio Liberty is a two-wheeled scooter from the Italian manufacturer Piaggio.
The first Liberty was built in 1997, after which it was restyled in 2004 and then again in 2009. It is a popular scooter among couriers and postal delivery companies around Central Europe.
History
[edit]First series (1997–2004)
[edit]
Presented at the Barcelona motor show in May 1997, the Liberty was born as a scooter with a 50 cm3 engine intended primarily for young audiences, having highly innovative specifications, it immediately stands out as "high wheels" among the most popular on the market; thanks to its original and dynamic line, good design quality and competitive price.[1]
In September of the same year, the version with a 125 four-stroke engine was presented at the Milan show and went on sale a few months later.[2]
In 1999 the Liberty LE 150 was introduced with the 150 cm3 four-stroke engine equipped with catalyst approved Euro 1 followed in December of the same year also by the 50 LE and 125 LE models approved Euro 1.[3]
Second series (2004–2009)
[edit]In the first months of 2004 the Liberty underwent a profound restyling both in terms of aesthetics and mechanics: a novelty is the departure of the 150 cm3 engine replaced by the new 200 cm3 four-stroke.[4]

The basic model with a displacement of 50 cm3 was proposed both in version with two-stroke engine and with four-stroke engine. The higher displacements are instead exclusively four strokes.[5]
From the middle of the year 2006 the sports version, the Liberty S, came on the market, characterized by a fairing similar to the Beverly 125 and an unprecedented instrumentation. It was slightly updated further in 2007 by re-proposing the 150 engine instead of the 200 cm3. A peculiar trait, in its category, is the attention to detail and the evident search to present captivating and well-finished finishes together with original saddle fabrics.
The Liberty Delivery 125 cm3 version was also chosen by Poste Italiane as a scooter for the distribution of correspondence.[6] As same to Austria[7] and Hungary.[8]
The Liberty has a single cylinder engine air-cooled for all versions, "LEADER" for 125 and 150 cm3 and "HI-PER" for 50 cm3.
The presence of high wheels limits the capacity of the compartment under the saddle that it can contain various objects and just a jet helmet; on the other hand, the large tank guarantees good autonomy.
Third series (2009–2013)
[edit]In 2009 the third series of the Liberty was presented, available in the displacements 50 cm3, engine to choose between two-stroke and four-stroke, 125 cm3 and 150 cm3. New features are a 10 mm lower seat, 10-spoke alloy wheels and a new 240 mm front disc brake. The design are more captivating, the rear part in particular has been completely modernized, adopting more angular lines for the headlight and the arrows.[9]
In November 2009 the limited edition Liberty Elle was presented, created together with the Elle magazine and intended for women. This model has a pink body with matching top case, 50 four-stroke or 125 four-stroke engine and seat lowered by 20 millimeters. It has been on sale since March 2010.[10]
The Liberty Teens, a special edition with two-tone pearl white/denim blue bodywork, and an electric prototype based on the Liberty Delivery for commercial fleets are presented at EICMA 2010.[11] The Teens special model will go on sale in May 2011 with a 50 two-stroke engine only.[12]
On 1 March 2012, production also starts in Vietnam for the Asian market.[13]
Fourth series (2013–2016)
[edit]In July 2013, the fourth series was presented, the range of which is divided into 50 models (two and four-stroke) and the brand new Liberty 3V from 125 and 150 cm3 (four-stroke). Aesthetically, the models are identical but the Liberty 3V 125 and 150 have a different and unprecedented chassis.
The fourth series is characterized by the new front shield with the "tie" grille that houses the Piaggio logo, the new front direction indicators with a more pointed "arrow" design are also introduced. The headlight is now triangular in shape. The new chrome inserts positioned on the fenders make their debut on the side, a chrome band is also mounted and on the front glove box. The saddle is new and has better padding, the underseat compartment is enlarged by 23% up to a volume of 10.8 liters, the battery is moved behind the front storage compartment.[14]
The fourth series maintains the same chassis as the previous one but in the models with the 50 engine it has a length of 1,935 mm, a width of 760 mm and a wheelbase of 1,320 mm. The front wheel of the fifties is 16" with a 90/80 tire, the rear is 14" with a 110/80 tire. The seat of the 50 is 785 mm high and the tank has a capacity of 6 liters.
The 3V models (with 125 and 150 cm3 engine) have a length reduced to 1,920 mm, a width of 700 mm with a wheelbase increased to 1,345 mm. The front wheel of the 3Vs now has a 15" diameter (on the third series they were 16") and is fitted with a narrower but wider shoulder tire (80/90). The rear wheel is always 14" with a 100/80 tire. The seat of the 3V is 790 mm high and the tank has a capacity of 6.5 liters.
The braking system is the same on all models and consists of a 240 mm front disc with double piston caliper while at the rear it adopts a 140 mm drum.[15]
Fifth series (from 2016)
[edit]The fifth series debuts at EICMA 2015 and enters production in early 2016. A novelty is the departure of the 50 two-stroke engine, the range is now composed of 50, 125 and 150 engines all belonging to the "I-Get" family Euro 4 approved four-stroke and three valves.[16]
It remains faithful in design to the previous generation by introducing only minor aesthetic updates such as a new front shield with more rounded and streamlined profiles with the larger headlights that on the 125 and 150 models have LED position lights. The chassis, on the other hand, is totally new and all versions use the same wheels and tires (with no differences between the various displacements). The newly designed frame has a torsional stiffness increased by + 15% while the flexural stiffness has been increased by + 17%, the front hydraulic fork has an excursion of 76 mm, while at the rear there is a shock absorber with a 73.5 mm stroke on the 50 while on the top of the range 125 and 150 there is a hydraulic shock absorber with adjustable preload on 5 positions and stroke of 74.5 mm.[17]
The compartment under the saddle is enlarged up to 17 liters, while the compartment in the front shield now has a capacity of 4 liters and also has a USB input and Piaggio Multimedia Platform system that allows you to connect the vehicle with your smartphone. The front wheel for all models is 16 "with a 90/80 tire, the rear 14" with a 100/80 tire. The braking system consists of a 240mm front disc and 140mm rear drum. The 125 and 150 have front wheel ABS as standard. The dimensions are: length equal to 1945 mm, width 690 mm, wheelbase of 1370 mm, saddle height equal to 780 mm (on the fifties) and 787 mm (on the 125/150). The tank on all models has a capacity of 6 liters (including 1.5 liters of reserve).[18]
In 2021 the engine range is re-approved Euro 5. In March 2022 the special version Liberty Baci Perugina was introduced, created in collaboration with Perugina to celebrate the centenary of the chocolate Bacio.[19]

Early adopters appreciated its affordability and ease of maintenance, making it a favored choice for commuters and delivery services in Europe.[17][18] In the following years, the range expanded with the addition of a 125 cc four-stroke variant in 1997 and a 150 cc four-stroke variant in 1999, providing smoother operation and greater power for longer trips while maintaining the model's compact footprint. These updates included catalytic converters to meet Euro 1 emissions standards, reflecting Piaggio's early commitment to environmental compliance amid tightening regulations.[19][20] The first series established the Liberty as a reliable urban mobility solution, with strong initial sales driven by its blend of style, functionality, and value, setting the stage for subsequent refinements in later generations.[5]Second series (2004–2009)
The second series of the Piaggio Liberty, produced from 2004 to 2009, represented the first major restyling of the model since its debut, drawing inspiration from the successful Beverly 500 scooter to modernize its appearance while maintaining its urban utility focus. This update featured sharper, less rounded bodywork lines, including a wider front shield with aerodynamic "moustaches" for improved airflow and a more prominent headlight assembly, contributing to enhanced overall aerodynamics suitable for city riding. The design also incorporated a flatter and wider footboard, providing about 10% more internal storage space compared to the previous series.[21] Building on the foundation of the first series, the second generation offered 50 cc two-stroke and four-stroke variants, the 125 cc four-stroke air-cooled unit, and replaced the 150 cc with a new 200 cc air-cooled Leader engine with two valves, optimized for urban performance and delivering reliable low-end torque, which expanded the lineup for riders seeking slightly more power without requiring an advanced license in many regions. This 200 cc variant, priced at approximately €2,595 at launch, was offered alongside the existing displacements but saw limited long-term adoption, with subsequent generations prioritizing the 150 cc option in response to market preferences for lighter, more agile configurations.[21][22] Ergonomic refinements in this series included a lowered saddle height to improve ground reach for a broader range of riders, along with adjustments to accommodate two-up riding more comfortably, enhancing everyday usability. Color options were expanded to include fresh schemes that complemented the updated aesthetics, though specific palettes varied by market. The model's reliability and practicality led to its adoption by postal services, notably Poste Italiane, which integrated thousands of Liberty units into delivery fleets for their maneuverability and low maintenance needs, with over 46,000 deployed in Italy overall.[21][23]Third series (2009–2013)
The third series of the Piaggio Liberty, launched in 2009, introduced enhancements focused on improved rider accessibility and modern aesthetics while maintaining the scooter's core urban mobility appeal. A key update was the option for a lowered seat height, reduced by 10 mm from the standard, to enhance ground reach and ease of handling for shorter riders. This change was particularly prominent in the women's-oriented Liberty Elle edition introduced in 2009. Additionally, the series adopted a 240 mm front disc brake with a dual-piston caliper paired with a 140 mm rear drum, improving stopping power over previous drum-only setups. Revised styling included sleeker bodywork with chrome accents on indicators, fork protectors, and the instrument panel, giving the scooter a more contemporary profile without altering its high-wheel design.[24][25] The engine lineup continued from the second series, offering air-cooled 50 cc, 125 cc, and 150 cc four-stroke options compliant with Euro 3 emissions standards, emphasizing reliability for city commuting. In 2009, Piaggio debuted the Liberty Elle special edition, tailored for female riders with vibrant pink bodywork, dedicated "Elle" graphics on the sides and leg shield, and matching accessories like a pink "Venere" helmet with branded stitching. This edition prioritized feminine styling while incorporating the lowered seat for practicality, along with under-seat storage for a demi-jet helmet and a 7-liter fuel tank. The following year, in 2011, the youth-focused Liberty Teens edition arrived exclusively with a 50 cc two-stroke engine, featuring a fresh white livery accented by dark blue on the footrests, leg shield, moldings, and a jeans-inspired saddle with Piaggio branding. Targeted at younger users, it highlighted agile handling and stylish cues to appeal to teens entering the riding market.[24][26] To meet growing demand in Asia, Piaggio expanded production capabilities in Vietnam starting in 2012 with the opening of a dedicated engine manufacturing facility in Vinh Phuc province near Hanoi. This complemented the existing vehicle assembly plant operational since 2009, enabling local production of Liberty scooters—including 125 cc and 150 cc variants—alongside Vespa and Fly models, with an initial engine output exceeding 200,000 units annually. The move supported regional market growth, where the Liberty's practical design resonated with urban commuters, and boosted Piaggio's global supply chain efficiency.[9]Fourth series (2013–2016)
The fourth series of the Piaggio Liberty, introduced in 2013, marked an engineering-focused evolution with the launch of the Liberty 3V variant, featuring new three-valve, single-cylinder, four-stroke, air-cooled engines in 125 cc and 150 cc displacements equipped with electronic fuel injection.[27] These engines incorporated reduced-friction components, such as roller rockers and optimized crankshaft design, along with enhanced fluid dynamics for improved efficiency and performance.[27] A key structural update was the adoption of a new high-strength tubular steel chassis, which enhanced overall rigidity, stability, and handling while maintaining the scooter's compact dimensions of 1,920 mm in length and a 1,345 mm wheelbase.[27] This frame design contributed to better braking efficiency and maneuverability, paired with a 15-inch front wheel (80/90 tire) and a 14-inch rear wheel (100/80 tire).[27] Additionally, under-seat storage capacity was enlarged by 23% to 10.8 liters, sufficient to accommodate a full-face helmet, complemented by a luggage hook and flat footboard for practicality.[27] The series complied with Euro 3 emissions standards through advanced fuel injection systems, including a Lambda probe and electronic control unit for precise mixture management, aligning with European regulatory requirements effective for new models in 2013.[28] This iteration built briefly on the special editions of the prior series, emphasizing mechanical refinements over aesthetic changes, and remained in production through 2016.[29]Fifth series (2016–2024)
The fifth series of the Piaggio Liberty, launched in 2016, introduced the i-Get family of engines across the 50 cc, 125 cc, and 150 cc displacements, all compliant with Euro 4 emissions standards. These air-cooled, four-stroke single-cylinder engines featured electronic fuel injection and improved efficiency, marking a shift toward more environmentally friendly and reliable powertrains while maintaining the scooter's urban agility. The series also featured an enlarged under-seat storage capacity of 17 liters, accommodating a full-face helmet.[30][5] In 2021, the lineup achieved Euro 5 compliance through refinements to the i-Get engines, including optimized air-cooled single-cylinder designs that reduced emissions and consumption without sacrificing performance; for instance, the 125 cc variant delivered approximately 11 hp and up to 110 mpg. This update also brought single-channel ABS as standard on the front disc brake for both 125 cc and 150 cc models (with the 150 cc having received it earlier in 2017), enhancing braking safety in city conditions. Additionally, USB charging ports became a standard or readily installable feature on these models, supporting modern rider connectivity.[31][32][33][34] The series saw aesthetic enhancements with the 2022 Baci Perugina special edition, limited to the 150 cc i-Get Euro 5 engine and featuring a deepest blue body with star motifs, a brown leather seat inspired by Perugina chocolates, and branded helmets, celebrating a century of the iconic Italian confection. In 2023, the Liberty S variant debuted with sporty styling accents, including black detailing on 14-inch rims, red stitching on the seat, and a rugged side cover for a more dynamic urban presence across 50 cc to 150 cc options. These iterations prepared the groundwork for the model's full redesign in 2025.[35][36]Sixth series (2025–present)
The sixth series of the Piaggio Liberty was unveiled at EICMA 2024, marking a significant redesign for the iconic scooter.[37] It entered the market on February 24, 2025, continuing Piaggio's tradition of blending urban practicality with Italian styling.[2] This iteration features updated styling with enhanced body lines that emphasize a more dynamic and protective profile, including a horizontal LED headlight and optional windshield for improved weather resistance.[6] The design incorporates lightweight cast aluminum three-spoke split rims, contributing to a sportier aesthetic available in both classic and S (Sport) variants with satin and glossy finishes.[38] For enhanced ride quality, the scooter employs a 16-inch front wheel and a 14-inch rear wheel, fitted with 90/80-16 and 100/80-14 tires that better absorb road irregularities.[6] These larger wheels, a hallmark of high-wheel scooters, promote stability and comfort in urban environments.[39] The sixth series builds on the i-get engine platform from the previous generation, offering air-cooled, four-stroke single-cylinder options in 50 cc, 125 cc, and 150 cc displacements, all compliant with Euro 5+ emissions standards.[39] It is available starting at $2,699 for the base 50 cc model, with the 150 cc version priced from $3,299, maintaining affordability while introducing modern digital features like a 5.5-inch color LCD display.[2]Design and Features

The Piaggio Liberty scooter has primarily utilized air-cooled, single-cylinder four-stroke engines across its generations, with displacements of 50 cc, 125 cc, 150 cc, and a limited 200 cc variant introduced in the second series (2004–2009). These engines feature overhead camshaft designs and have evolved to meet progressively stricter emissions standards, starting with Euro 1 compliance in 1999 for initial models and advancing to Euro 5 by 2021. Fuel tank capacities have remained consistent at 6 to 6.5 liters, supporting efficient urban commuting. All variants employ a standard continuously variable transmission (CVT) with belt drive for seamless power delivery.[3][41][47] Early engines in the first series (1997–2004) included a 50 cc two-stroke option producing approximately 4.1 hp, alongside four-stroke versions for larger displacements: the 125 cc Leader engine delivering around 12 hp and the 150 cc variant at about 14 hp. These were carbureted units designed for reliability and low maintenance, with the two-stroke 50 cc phased out by the mid-2000s in favor of four-strokes to align with emissions regulations. The brief 200 cc four-stroke engine, offered from 2005 to around 2008, provided 12.5 hp (9.1 kW) and enhanced torque for heavier loads, but was discontinued due to market preferences for smaller engines.[48][49][47] From the third series (2009–2013), engines transitioned to Euro 3 compliance with improved catalytic converters and refined carburetion, maintaining the 50 cc (3.3 hp), 125 cc (12 hp), and 150 cc (14 hp) lineup. The fourth series (2013–2016) introduced three-valve heads on select models for better airflow and efficiency. A significant advancement occurred in the fifth series (2016–2024) with the adoption of i-Get technology, featuring electronic fuel injection, three-valve distribution, and an automatic start-stop system to reduce idle emissions and fuel use. These i-Get engines achieved Euro 4 standards initially, progressing to Euro 5 by 2021 with enhanced exhaust aftertreatment. The 50 cc i-Get produces 3.3 hp, the 125 cc around 11 hp, and the 150 cc up to 12.7 hp, emphasizing low vibration and extended service intervals.[30][50][51] In the sixth series (2025–present), the i-Get engines continue with Euro 5+ refinements as of 2025, including optimized combustion for further emissions reduction while preserving the core architecture of air-cooling and single-cylinder design. This evolution reflects Piaggio's focus on balancing performance, environmental compliance, and urban practicality across all variants.[39][52][53]| Displacement | Power Output (approx.) | Key Features | Emissions Standard Introduction |
|---|---|---|---|
| 50 cc | 3.3 hp | Four-stroke (post-2004), i-Get with EFI and start-stop (2016+) | Euro 1 (1999), Euro 5 (2021) |
| 125 cc | 10.9 hp (2025) | Three-valve head (2013+), electronic injection (2016+) | Euro 3 (2009), Euro 5+ (2025) |
