C50 C90 C109R M50 M90 M109R S40 S50 S83

Suzuki Boulevard is a cruiser series launched in 2005 by Suzuki Motor Corporation, which was the result of combining and slightly redesigning models from the Intruder, Marauder, Desperado, Volusia, and Savage series. Within this series, there are three model groups:

C — classic American cruisers with wide wheels and expressive fenders. This category includes three models: the C50 (2005), previously known as the Volusia 800, the C90 (2005), which was renamed from the Intruder 1500 LC, and the C109R (2008), all with 32-bit electronic fuel injection.

S — cruisers and choppers with a narrow, large-diameter front wheel and a strongly raked fork. The model range includes three models: S40 (which is an unchanged Savage 650), S50 (which is a Suzuki Intruder 800 with a new seat and air filter) and S83 (similar to the Suzuki Intruder 1400, similar to the S50).

M — power-cruiser. Initially, this range included only the M50 model (Marauder 800 with electronic injection and some cosmetic improvements), but later completely new models M109 (2006) and M90 were added, which have the same frames, but differ in engine capacity. These motorcycles stand out for their futuristic design, contrasting with the classic forms of the S and C models.

Motorcycles in this series are primarily aimed at the American market, so their designations include the engine capacity in cubic inches. The same models are supplied to Europe under the Intruder brand with similar model series letters and indexes indicating the working volume in cm³.

Boulevard C50 (2005-current)

The Suzuki VL800 Intruder cruiser, also known as the Volusia, was introduced in 2001 as a classic version of the Suzuki VS800 Intruder. It was produced alongside the VS800 until 2004, and continued to be produced in the US market until 2009 under the name Boulevard S50. In Japan, this motorcycle was sold under the name Suzuki Intruder 800 Classic and remained on sale until 2006.



Since 2005, the VL800 Volusia has undergone significant changes and was renamed the Suzuki Boulevard C50 for the US market and the Suzuki Intruder C800 for Europe and other countries. The updates concerned both the exterior design — the air filter cover, taillight and headlight were changed, and the technical specifications — the motorcycle received an injector and the fuel tank capacity was reduced from 17.0 to 15.5 liters.

In 2006, two new versions were introduced: Suzuki Boulevard C50C (Intruder C800C) and Suzuki Boulevard C50T. The first of them stood out with the presence of cast tubeless wheels, and the second — with touring equipment, including a windshield, panniers, a backrest and a riveted seat, as well as tires with a white stripe.



In 2009, the Suzuki Intruder C800 (Boulevard C50) model received an SDTV dual throttle valve injector, and in 2016, its sale in Europe was discontinued. Currently, the motorcycle is only available in the US market in two versions — Suzuki Boulevard C50 (with spoked wheels) and Suzuki Boulevard C50T.

The Suzuki Boulevard M50 (Intruder M800) was developed on the basis of the Suzuki Intruder 800 Volusia and Suzuki Intruder C800 (Boulevard C50), which became the successor to the Suzuki VZ800 Desperado (Marauder).



In addition, the Japanese market offered a 400 cc version of these models — the Suzuki VL400 Intruder Classic, which was discontinued in 2016.

The main competitors of the Boulevard C50 in its class are the Honda VT750 Shadow, Kawasaki VN800/VN900 Vulcan and Yamaha Drag Star 1100.

Boulevard C90 (2005-current)

The Suzuki VL 1500 Intruder LC and Boulevard C90 are cruiser motorcycles known for their feet-forward riding position, shaft drive, and engine balance shafts. Produced by Suzuki from 1998 to 2004 under the Intruder name, these models transitioned to the Boulevard branding starting in 2005.

After the VL series concluded with the 2004 model year, Suzuki introduced the fuel-injected Boulevard C90 in 2005, which continued in production until 2010, and was reintroduced in 2013.



The original Suzuki VL 1500 Intruder LC featured a seat height of 680 mm and a 13-liter fuel tank located beneath the seat. This model was equipped with an engine capable of delivering a claimed output of 50 kW (67 hp) at 4800 rpm and a torque of 114 N⋅m at 2300 rpm. Notable enhancements in 2004 included the addition of a four-way emergency flasher/high beam passing switch, multi-reflector turn signals, hydraulic valve lash adjusters, a hydraulic clutch, and a back-torque limiter.

The designation VL signifies the V-twin engine and "long" frame, while 1500 indicates the engine's approximate metric displacement, and LC stands for Legendary Classic.



In 2005, Suzuki rebranded its cruiser lineup as the Boulevard series, renaming the VL1500 to Boulevard C90. Beyond the name change and aesthetic updates, the new model featured a multi-port fuel-injection system derived from Suzuki's GSX-R racing motorcycles, replacing the previous carburetor. Additionally, a 32-bit ECU processing chip was introduced, along with a slightly modified 14-liter fuel tank.



The new fuel-injection system enhanced the engine's torque and acceleration, incorporating dual throttle valves and an automatic fast-idle feature. The engine maintained its performance figures of 50 kW (67 hp) at 4800 rpm and 114 N⋅m at 2300 rpm, utilizing SCEM cylinder plating for improved durability. Production of the C90 resumed with the 2013 model year.

The main competitors of the Boulevard C90 are the Honda VTX 1300, Kawasaki VN1500 Vulcan and Yamaha XV1600.

Boulevard C109R (2008-2013)

The Suzuki Boulevard C109R was introduced in 2008 as the most powerful and large capacity classic cruiser in the Suzuki motorcycle lineup. This motorcycle was available in most global markets, including Japan, North America, Europe and Oceania. Outside North America, it was sold as the Suzuki C1800R Intruder, and the factory model designation was VLR1800.



The Suzuki Boulevard C109R and Intruder C1800R are based on a 1783 cc, 54° V2 engine. This engine is capable of producing up to 114 hp and 157 Nm of torque. It is equipped with a dual throttle injection system (SDTV — Suzuki Dual Throttle Valve), a 32-bit control unit and a semi-dry sump, implemented using SASS (Suzuki Advanced Sump System) technology. This engine is a modified version of the engine used in the Suzuki Boulevard M109R (Intruder M1800R).



As for the chassis, the Suzuki Boulevard C109R (Intruder C1800R) has a classic steel frame, simple suspension in the form of a non-adjustable telescopic fork with a diameter of 49 mm and a monoshock absorber with preload adjustment. The braking system includes 3-piston calipers at the front, as well as a 5-speed transmission and a cardan drive to the rear wheel.

Among the main modifications of the Suzuki Boulevard C109R are:

• Suzuki Boulevard C109R (Intruder C1800R) — standard version.
• Suzuki Boulevard C109RT (Intruder C1800RT) — touring version, which is equipped with a windshield, passenger backrest with luggage rack, panniers and a riveted seat.

2013 was the last year of production of this model, after which it was withdrawn from the market.

The main competitors of the Suzuki Boulevard C109R in its class include the Honda VTX1800, Kawasaki VN2000 Vulcan and Yamaha XV1900.

Boulevard M50 (2005-2019)

The Boulevard M50, known as the Intruder M800 in markets outside North America, is a cruiser motorcycle featuring a V-twin engine, produced by Suzuki Motor Corporation. The global model designation for this bike is VZ800; prior to 2005, this designation was associated with the Marauder 800, a distinctly different model. The M50 is derived from the well-regarded VL800 C50, where the 'C' stands for 'classic'. Initially, the VL800 C50 was referred to as the VL800 Intruder Volusia, but this name was later shortened to simply Volusia. Its design draws inspiration from the first generation of the VZ800 Marauder. In 2005, Suzuki revamped the model by replacing the carburetors with a fuel injection system, leading to the new name: 'M' for 'muscle' and '50' indicating the engine displacement in cubic inches. The Intruder M800 refers to the 800 cubic centimeter engine, adhering to Suzuki's naming conventions for cruisers outside of North America.



The M50 was built using the frame and rear swingarm of the C50, featuring a softail design with a concealed single shock absorber, in contrast to the Marauder's traditional swingarm equipped with two visible shock absorbers. The M50 also boasts unique fenders and a fuel tank distinct from the C50, along with a handlebar-mounted speedometer and inverted 41mm front forks, contributing to a more robust aesthetic compared to its semi-sibling, the C50. The engine of the M50 was slightly altered, finished in black rather than the chrome seen on the C50's engine. Internally, it received split crank bearings instead of the one-piece bearings used in the C50, as well as modified valvetrain components, which required changes to the cylinder heads. Despite these modifications, the power output remains the same as that of the C50, with both engines displacing 805 cc. They share a 5-speed transmission housed in a common crankcase, equipped with a wet clutch, water cooling, a single front disc brake, and a rod-operated rear drum brake.



The M50 is characterized by its distinctive styling, featuring a unique rear fender, an LED taillight, black-painted mag wheels, and an aggressive stance. Additional subtle differences separate the M50 from the C50, including variations in front brake disc designs (though they are the same size), a slightly firmer suspension on the M50, and a different toolbox/faux air cleaner. The motorcycle received positive reviews from the press, with Motorcycle Cruiser Magazine praising its comfort and passenger capacity. However, some critics noted that the M50 lacked the power to match its muscular appearance. Ultimately, it did not achieve top sales figures, and after five years in production, Suzuki opted for a complete redesign of the model.



In 2010, the M50 underwent a significant overhaul. The original M50 engine was discontinued, and the new model now utilizes the same engine as the C50, streamlining production and simplifying parts procurement. The sheet metal design was altered, replacing the distinctive rear fender of the 2005–09 models with one similar to those found on other cruiser models. A small cowling was added around the headlight, giving the M50 a family resemblance to other Suzuki M series cruisers, such as the M90 and M109R. Sales figures for the redesigned M50 remain unavailable, as Suzuki decided not to ship any 2010 models to North America due to an oversupply of 2009 models in dealer inventories.



The main competitors of the Suzuki Intruder M800 (Boulevard M50) in the class: Honda Shadow 750, Kawasaki VN900 Vulcan, Yamaha Midnight Star 950.

Boulevard M90 (2009-2019)

The Suzuki VZ1500 Intruder cruiser was first introduced in 2009 and was intended for the North American, European and Oceanian markets, where it was sold under various names:

• Suzuki Intruder M1500 — model for all regions except North America.
• Suzuki Boulevard M90 — version for the North American market.

The Suzuki Intruder M1500 and Boulevard M90 are based on the frame from the flagship Suzuki Intruder M1800R (Boulevard M109R) model, as well as a redesigned engine from the Suzuki VL1500 Intruder. This engine is equipped with liquid cooling, increased compression ratio, four valves per cylinder and a number of other improvements, which increased the maximum power to 106 hp and torque to 137 Nm.



In other respects, the Suzuki Intruder M1500 and Boulevard M90 were similar in many ways to the M109R. Suzuki's marketing strategy was to offer a more affordable alternative to the M109R, while preserving its appearance and characteristics as much as possible.



Despite the interesting concept, demand for the Suzuki Intruder M1500 and Boulevard M90 outside of America was quite low. As a result, the model gradually disappeared from the range of European dealers, and the name itself became less popular. Today, only the American versions of the Boulevard M90 remain on the market, which continue to be produced.



In 2013, the liquid engine from the Suzuki Boulevard M90 was transferred to the classic version of the Suzuki Boulevard C90, which received the designation B.O.S.S. Despite the same engines, the C90 and M90 have different power and torque figures — the classic version of the C90 is "limited" to 79 hp. 2019 was the last year of production of this model.

The main competitors of the Suzuki VZ1500 Intruder (Boulevard M90) in its class are the Kawasaki VN1500/VN1600 Mean Streak and Yamaha XV1700 Warrior.

Boulevard M109R (2006-current)

The Suzuki Boulevard M109R cruiser was introduced in 2006 as the flagship muscle bike in the Suzuki model range. In Europe, this motorcycle is known as the Suzuki Intruder M1800R and is aimed at the markets of North America, Europe and Australia.



The basis for the Suzuki Boulevard M109R was a 2-cylinder V-shaped engine with a 54° angle of collapse, having a volume of 1783 cc. This engine develops a power of 125 hp and a torque of 160 Nm. Maximum speed is limited to 7500 rpm, and maximum torque is achieved already at 3200 rpm. The engine is equipped with an injector with dual throttle valves (SDTV system — Suzuki Dual Throttle Valve), a 32-bit control unit and a lubrication system with a semi-dry sump (SASS technology — Suzuki Advanced Sump System). Later, a modified version of this engine was installed on the Suzuki Boulevard C109R (Intruder C1800R).



As for the chassis, the Suzuki Boulevard M109R and Intruder M1800R have a steel duplex frame, an inverted fork with a diameter of 46 mm, cast wheels with a diameter of 18 inches, front 4-piston brakes with radial calipers, a shaft drive and a 5-speed transmission.

In 2008, a version with a naked headlight (without a fairing) was released — Suzuki Boulevard M109R2, which was sold until 2009, after which it disappeared from the dealers' assortment.



Since 2014, the Suzuki Boulevard M109R (Intruder M1800R) model has received a black version, known in the North American market as B.O.S.S., and in other countries as the Black Edition. The main changes are the absence of chrome parts, which were replaced by black elements, as well as a two-tone paint job.

To date, in most countries, only the black version of the Suzuki Boulevard M109R (Intruder M1800R) is available, while the standard model is practically not represented on the market.



The main competitors of the Suzuki Boulevard M109R in its class are the Honda VTX1800 and the Kawasaki VN2000 Vulcan.

Boulevard S40 (1986-2020)

The Suzuki Boulevard S40 (formerly the Suzuki LS650 Savage) is a cruiser motorcycle manufactured by Suzuki Motor Corporation for the Japanese market and exported to New Zealand, North America, as well as Chile and other countries. Since January 2015 the S40 has been sold in Australia for the first time since the 4-speed LS650 motorcycle became available in the 1980s. Its last year of production was in 2020.



Manufactured and marketed as the Savage from 1986 to 2004, the motorcycle was renamed for the 2005 model year as the Boulevard S40. The LS650 has remained largely unchanged, other than a few cosmetic changes. Receiving a 5-speed transmission instead of a 4-speed in 1993. With a curb weight of 173 kg, Suzuki markets the S40 as a beginner's motorcycle as an introduction to its cruiser line. With a shorter height of 711 mm and straighter handlebars, the bike is suitable for tall and short riders.



The LS650 Savage was the first cruiser manufactured by Suzuki in 1986. The Kawasaki Vulcan 400 entry-level cruiser with a V2 engine was introduced the same year, and the Vulcan 500 LTD with an inline 2-cylinder engine was introduced in 1985 and 1990. One of the few cruisers with a shaft and driveshaft instead of a chain or belt drive, the Yamaha Virago 535 was introduced in 1987. Honda launched the Shadow VLX, with a 583 cc V2 engine in 1988. 1988 to compete against the Savage. The Savage was a very measured bike, with a high-torque engine (although low-powered for its displacement) that put little demands on its rider.



Compared to the discontinued Buell Blast, which had a 492 cc single-cylinder engine with slightly more vibration, the S40 is more versatile and economical.

The Boulevard S40 fills the gap between the less powerful 250 cc cruisers and the more powerful 2-cylinder cruisers in the 500-650 cc range. Competition for the S40 from lesser cruisers comes from the Yamaha V-Star 250 and the Honda Rebel 250. Although some consider the S40 too powerful for a novice rider, the low weight and low seat height make it a favorite for beginners who think 250cc motorcycles are too small. The S40 has its larger rivals in the Yamaha V-Star 650 Custom, as well as the Honda Shadow Spirit 750, which feature super-low seats. Similarly, the Sportster XL883L "Low", and the "SuperLow", are Harley-Davidson's entry-level motorcycles.



The Boulevard 40's engine is a 652 cc, 4-stroke, air-cooled, SOHC, dual-turbo combustion chamber (TSCC) design first used on the Suzuki GSX series that improves combustion efficiency and reduces pollution. This engine has a rocker arm crankshaft, and produces 38.5 hp. At 97 kilometers per hour the engine turns at 3940 rpm.

In 1996, Motorcycle Consumer News measured an LS650 Savage's rear-wheel speed of 24.6 hp and 41.4 Nm of torque. The LS650 achieved a quarter-mile time of 15.3 seconds at 130.5 km/h and averaged 4.7 L per 100 km. In 2006, Motorcycle Cruiser magazine measured an S40's quarter-mile time of 16.35 seconds at 124 km/h. Average fuel economy was 4.4 L per 100 km.
