The Streetfighter's Superbike soul combines fighter attitude and naked sophistication to create pure adrenaline. ‘S' treatment of the Streetfighter pushes its tech spec to the red line.
Ducati’s ‘S’ treatment of the Streetfighter pushes its tech spec to the red line. Öhlins suspension front and rear and lightweight Marchesini forged wheels stack up serious credibility, while the front fender and cam belt covers in super-light carbon fibre help reduce the dry weight to an extreme 167kg (368lb).
But the ‘S’ sophistication doesn’t end there. Awesome street-going Ducati Traction Control and Ducati Data Analysis are standard issue, making it clear that the Streetfighter S is not all muscle – it’s intelligent too.
Intelligent muscle
The Streetfighter S was Ducati’s first ever naked sportbike to be fitted with their awesome Ducati Traction Control (DTC) system.
Accessible from the left-hand switchgear and displayed on the digital instrumentation, the system offers a choice of eight profiles, or ‘sensitivity levels’, each one programmed with a wheel-spin tolerance matched to progressive riding levels of skill, graded from one to eight.
While level eight administers a confidence-building, high level of interaction from the system by activating upon the slightest amount of wheel-spin, level one offers a much higher tolerance, resulting in less intervention for highly competent riders. Once the level is selected and DTC activated, both are displayed on the Streetfighter instrumentation. The system then analyses data sent from front and rear wheel speed sensors to detect wheel-spin. Should the system recognise wheel-spin above a certain threshold, the DTC ECU instantly evaluates the many possible wheel-spin scenarios before administering two types of interaction in varying amounts.
DTC is able to sense the exact use that the Streetfighter is being put to. From slow mid-corner acceleration with considerable vehicle inclination to high speed corner exits while almost upright, DTC is intelligent enough to react according to each and every situation. It’s even smart enough to not intervene if you decide to perform a burnout or a wheelie.
The first ‘soft’ stage of system interaction is executed by high speed software that instantly makes
electronic adjustment to the ignition by administering varying amounts of retardation to reduce the engine’s torque output. During this initial stage of DTC interaction, both outer warning lights on the Streetfighter instruments – normally used to signify over-rev – illuminate to signify that DTC is being applied.
If the DTC software detects that the first ‘soft’ stage of system interaction is inadequate to control the
wheel-spin, it continues to administer ignition retardation and instructs the engine ECU to initiate a pattern of constantly increasing injection cuts until, if necessary, full injection cut. During this second stage of system interaction, both outer and central warning lights fully illuminate to signify that DTC has also initiated injection cuts.
After either stage one (ignition retardation) or stage two (pattern of injection cuts or full cut), the system incrementally returns to the original ignition and injection mapping as the wheel speeds approach equalisation. This carefully programmed return to full power delivery is the real key to DTC’s smooth and efficient operation.
In developing its World Championship-winning traction control system for road use, Ducati continue to demonstrate their strategy of transferring technologies from their race bikes into the production
environment, and show how solutions developed for performance on the track really can be applied to
enhance safety on the road.
Information is power
The Ducati Data Analyser (DDA) – complete with PC software, a USB-ready data retrieval card and
instructions – evaluates the performances of the Streetfighter and its rider, and provides a graphic
presentation of data from various channels of information. The DDA is available for the Streetfighter from Ducati Performance, and is supplied as standard equipment on the Streetfighter S.
Normally only available on race bikes, DDA records numerous channels of data including throttle opening, vehicle speed, engine rpm, engine temperature, distance travelled, laps and lap times. The system also automatically calculates engine rpm and vehicle speed data, enabling gear selection as an extra channel of information. A channel of data is also dedicated to recording the DTC index, which can then be viewed as a graphic trace that shows the amount of DTC interaction during wheel-spin. At the end of a ride or track session, 4mb of data can be downloaded to a PC ready to compare, analyse and get an inside view on the performance of the rider and Streetfighter.
Data can be analysed in graphic form with options to zoom into detail of specific sections. Dragging a trace along a timeline to reveal individual values of the above-listed channels enables the user to analyse performance in the same way that data technicians can in factory teams.
Soul of a Superbike – Attitude of a fighter
For 2011, the Streetfighter arrives with a new arctic white colour scheme, while the Streetfighter S gets a matching red Trellis frame for the red version and a racing black frame for the new diamond black. Both Streetfighter models get radiator covers in a new subtle black finish and both colour schemes of the ‘S’ now have black wheels.
The Ducati Streetfighter scored a round one knock-out when it entered the ring for the first time at the
Milan show back in November 2008. Its brutal elegance stole the ‘Most Beautiful Bike’ award and raised the bar for extreme nakeds. The Streetfighter and Streetfighter S first hit town in model year 2010 and their asphalt-ripping reputation was an instant hit with connoisseurs of sport nakeds.
The Streetfighter’s Superbike soul combines fighter attitude and naked sophistication to create pure
adrenaline. Stripped to the bare essentials, its combination of state-of-the-art race technology, skeletal
styling and contemporary design takes Ducati’s big naked concept to the very top of the fighter food chain.
The true Ducati spirit is captured by an incredibly powerful Desmodromic L-Twin 1098 “Testastretta
Evoluzione” engine producing 155hp with an incredibly wide spread of power thanks to 85lb-ft (11.7kgm) of torque. The Streetfighter’s power and precision is further maximised by weighing in at just 368lb (167kg) - S version - and further benefits from technology derived directly from Ducati’s MotoGP and Superbike projects. Ducati Traction Control and Data Analysis, racing-style braking system, fully adjustable suspension and forged wheels all come as standard equipment on the ‘S’ to complete the battle-ready package.
Streetfighter made good
The Streetfighter culture was born on the backstreets of Northern Europe during the late 70s and 80s. If the Café racer movement had taken traditional bikes and transformed them to establish out-and-out sportbikes, then Streetfighters were definitely anti-establishment. They evolved by removing the fairings from sport bikes, fitting higher bars and customising to create high-performance, over-the-top nakeds. Now, Ducati have taken that concept and applied their own Italian sophistication to a stunning, factory-prepared Streetfighter.
The Ducati Streetfighter is equipped with everything that made the Superbike a legend: Awesome L-Twin muscle with brutal, big-bore torque, thoroughbred chassis technology, beautiful single-sided swingarm, planet-stopping Monobloc brakes and pure, sophisticated class.
While the tank and seat shapes leave no doubt as to the Streetfighter’s roots, it is the upright and
commanding riding position that really starts to shape the character of this ultimate naked. Minimalistic
controls, instrumentation and headlight design leave the front looking clean and mean, while twin-stacked right-side mufflers at the rear leave the tail-end high and sharp. No other Ducati has ever achieved such an aggressive stance while providing a comfortable, empowering, controllable and enjoyable ride.
Ducati’s ‘S’ treatment of the Streetfighter takes its sophistication way off the scale. Superbike spec Öhlins suspension front and rear with lightweight forged Marchesini wheels add extra street credibility when in town and that all-important ‘feel’ when exploring the Streetfighter’s sports soul.
Add the awesome street-going Ducati Traction Control and Ducati Data Analysis as standard equipment and it’s clear that the Streetfighter S is not just muscle – it’s intelligent too.
Lifestyle
Ducati’s Streetfighter project was inevitable. The passion to build the most successful Superbikes ever, mixed with the desire to create iconic, naked motorcycles was a rush of adrenaline just waiting to happen.
Who else would create a bike for out-and-out purists to celebrate naked power in all its forms? A bike with muscle-engine performance, aggressive chassis engineering and intelligent electronics all laid bare to appreciate, respect and enjoy? Ducati build bikes for enthusiasts – for bikers who appreciate the details that come together to make an awesome bike, for perfectionists who instantly recognise excellence when they see it.
Ducati motorcycles aren’t just a means of transport, they enable a lifestyle that set their rider apart from the rest of the world. They’re an extension of character and the ultimate personal statement. The Streetfighter is built with pure Ducati passion and it’s ready to impress, whatever the lifestyle.
Take control
The Streetfighter riding position is empowering. The lightweight aluminium tapered bars are higher than on a Superbike, but still flat enough to ride hard, so machine control is enhanced and the relationship with the front-end remains in tact. Considerable study on seat, footpeg and handlebar position has maximised comfort without losing the feeling that you’re aboard an extreme naked Ducati.
Showing attention to detail typical of all new Ducatis, the handlebars are gripped by beautifully shaped
clamps that flow sleekly into the bar-risers. Even the switchgear presents minimalism at its best. The slimline bodies house easy-to-use switches and buttons and feature a unique weapons-like ‘trigger catch’ that slides down to cover the starter button when activating the kill-switch. Symmetrically mounted, remote brake and clutch reservoirs are small, low and compact and feed slim, radial master-cylinders by Brembo to complete the clean and uncluttered controls arrangement.
The Streetfighter’s instrumentation continues that same clean look with a compact shape that blends into the aggressive line of the headlight. Information additional to the default read-outs is managed from the lefthand handlebar-mounted switch gear, allowing the rider to scroll through and select from various menus.
The display presents rpm and speed, with the former displayed across the screen in a progressive bar
graph. Additionally, the instruments display lap times, DTC status and level selected (if activated on
Streetfighter S) time, air temperature, coolant temperature, battery voltage, two trips and a trip that
automatically starts as the fuel system goes onto reserve. Warning lights illuminate to signify neutral, turn signals, high beam, rev-limit, low oil pressure, fuel reserve, DTC intervention (if activated on Streetfighter S) and scheduled maintenance. The instrument display is also used as the control panels for the DDA and DTC systems as well as listing lap times recorded by using the high-beam flash button as a stopwatch.
A chassis born to fight
At a class-leading 169kg (373lb) dry weight for the Streetfighter and an incredible 167kg (368lb) for the Streetfighter S, both come to the fight with the highest power-to-weight ratio in their class. The purposebuilt Trellis frame, which uses 25.6° of rake compared with the Superbike’s 24.5°, ensures a well-planted front-end, while a 35mm longer single-sided swingarm at the rear ensures the Streetfighter’s acceleration need never be compromised. The longer, beautifully created aluminium swingarm follows the same dual construction detail as the Superbike models and is anodised finished in black.
The lower triple-clamp also gets more muscle development. Formed in a strength-enhancing gull-wing
shape for even more rigidity, it maintains a vice-like grip on the fork legs, giving a precise and solid feeling through the bars on fast direction changes.
The revised rake, longer wheelbase and cross-mounted steering damper ensure stability even under the extreme acceleration of Ducati’s incredible L-Twin torque.
Suspension
The Streetfighter is armed with fully adjustable 43mm Showa forks up front and a fully adjustable Showa monoshock at the rear, giving the bike high performance agility and the rider absolute ‘feel’ and confidence from sure-footed handling.
The forks feature a natural chrome slider finish and radial mounts for the brake callipers and are fully
adjustable in spring preload as well as compression and rebound damping. On the rear, the single Showa unit operates through a progressive linkage and is also fully adjustable in spring preload and damping, both in compression and rebound.
The Streetfighter S pushes the spec way up with 43mm Superbike-spec Öhlins forks that have sliders
treated in low-friction TiN. Fully adjustable in spring preload and precisely adjustable in compression and rebound damping, they ensure ‘S’ feeling and finesse when the fight gets rough.
Taking care of the rear of the ‘S’ is a single high-spec Öhlins unit fully adjustable in spring preload with full adjustment and highly engineered control of compression and rebound damping. The unit is also fitted with a ride enhancing top-out spring which helps maintain rear tyre contact under extreme conditions.
Important attention to performance detail is inherited from its Superbike bloodline with both the
Streetfighter and Streetfighter S having rear ride-height adjusters that allow fine correction after setting
personalised spring preload.
Wheels
10-spoke wheels in lightweight aluminium keep the overall motorcycle weight down and maintain an allimportant control on unsprung weight. This weight is made up of all the components between the
suspension and the road and consists of wheels, tyres, brake discs and callipers etc, but when rotating at high speed, it is the wheels that store most of the kinetic energy and offer the most resistance when
steering, accelerating or braking. Their weight saving, therefore, is a serious contribution to both the
handling and the performance of the bike and the Streefighter pulls out all the stops to be the best.
The Streetfighter S reduces weight even further by using Y-shaped, 5-spoke wheels by Marchesini, forged and then machined in lightweight aluminium. The Streetfighter wheels are finished in graphite grey, while the ‘S’ moves to black for 2011 with both models rolling out on Pirelli Diablo Corsa lll tyres.
Brakes
Both the Streetfighter and Streetfighter S use Brembo’s powerful Monobloc calliper race technology.
Machined from a single piece of alloy, the callipers achieve higher rigidity and resistance to distortion during extreme braking. The result not only delivers planet-stopping brake power, but also gives an enhanced and precise ‘feel’ at the brake lever. The twin Monobloc callipers each have four 34mm pistons that grip huge 330mm discs to achieve their spectacular performance. The weight of the discs has been kept to a minimum by using racing-style narrow braking surfaces.
Power house
The world-beating 1098 Testastretta Evoluzione needs little introduction. Debuting in 2007, it went on to form the basis of a motor that powered Ducati to Superstock and Superbike World titles that left the competition stunned. Now, its massive bore, short stroke and incredible torque powers Ducati’s most extreme naked and the results are equally as stunning.
Producing a ballistic 85lb-ft (11.7kgm) of torque and 155hp (114kW), the Streetfighter’s awesome 1098 power house fears nothing of the naked sports competition. The L-Twin, Testastretta Evoluzione engine gives both the best power-to-weight and the best torque-to-weight ratios in its class.
Surface features include enhanced detailing on the cam belt covers and the magnesium dry clutch cover as well as a new black finish for the main outer casings and carbon-grey finish for the crankcases, which employ the same weight-saving technology used for the 1198.
The vacuum die-cast process used to make the crankcases ensures consistent and precise wall thickness and increased strength from absolute material purity while reducing weight considerably.
Using the Testastretta narrow valve angle, super-straight intake ducts and specially shaped combustion
chambers, the Desmodromic motor continues to breathe through MotoGP-derived elliptical throttle bodies and four large diameter valves per cylinder to achieve its incredible spread of torque.
A high performance six-speed box and racing-style dry clutch makes sure the transmission package delivers 155hp as efficiently as possible.
The Streetfighter’s power house is protected by twin coolant radiators, carefully curved in pure naked style for optimum performance and stunning with visual effect. The upper radiator is assisted by lightweight, high flow electric fan assemblies while the lower sits in the front of the belly pan, which also houses a highly efficient oil heat exchanger.
Having more experience and success with twin-cylinder high performance engines than any other
manufacturer, the air-cooled L-Twin remains central to Ducati's philosophy of motorcycling. This
experience, plus constant investment in quality by design, advanced materials and engineering techniques, has enabled a distance between service intervals of 7,500 miles (12,000 kilometres), making Ducati ownership even more enjoyable than ever.
Cannon-style mufflers
The massive Streetfighter 2-1-2 exhaust system is made from weight-saving 1mm thick steel and flows
from 58mm to 63.5mm diameter pipes. The system uses two lambda probes to ensure precise fuel
mapping for optimum performance and an electronic valve in the mid-section to achieve a wide spread of power.
The cannon-style, vertically stacked mufflers sport the same finishes as the Superbike family: Brushed steel for the Streetfighter and black brushed steel for the Streetfighter S, both delivering the famous Ducati LTwin sound synonymous with raw, Desmo power.
Lighting
The aggressive looking headlight is the ‘face’ of the Streetfighter and it leaves little doubt as to its
character. While the main lighting source and multi-reflector design provides powerful illumination to cut through the night, its two evil eye strips of LED positioning lights give a striking and unmistakable identity to the bike.
Keeping design matters clean and stylish, the directional indicators remain unobtrusive with clear lenses and coloured bulbs, while the rear light is integral to the shape of the tailpiece, providing unobscured illumination while maintaining the smooth and elegant look to the high and sharp rear-end.
Naked detail
More attention to detail than ever before went into creating the Ducati Streetfighter. Repositioning many of the components usually hidden by bodywork and continuing to keep them out of sight was a major challenge for the design and engineering teams, but they’ve pulled it off with impressive results.
Add to this details such as the perfectly formed passenger seat cover, a rear hugger fitted as standard equipment and the pre-minimalised licence plate holder, and it’s plain to see that Ducati have gone that extra step to achieve the highest level of finish.
Streetfighter colours
While the Streetfighter looks stunning in either red or the new arctic white set against a black frame and subtle graphite grey 10-spoke wheels, the Streetfighter S positively seduces in red and menaces in a new diamond black with respectively matching red or racing black Trellis frames. The carbon fibre front fender and cam belt covers superbly match the black Y-shaped, 5-spoke wheels.
2011 Ducati Streetfighter S Technical Details
ENGINE
Desmodromics
The incredible valve performances of our engines are only possible because of Ducati's unique Desmodromic system, where valve closure is activated mechanically. At high rpm it would be almost impossible for the valve to follow the steep closure profile of the cam lobe if it were relying upon a normal valve spring. With the Desmo system, the valve is closed mechanically with the same accuracy as it is opened, enabling steep cam profiles and radical cam timings. This system is used on every single Ducati power unit including our world-beating Superbike and Desmosedici MotoGP engines.
Magnesium alloy covers
Attention to weight reduction is further underlined with both cam covers and clutch outer cover cast in manesium alloy.
Crankshaft
The streetfighter's lightweight crankshaft assembly operates a highly ‘over-square’ bore and stroke with huge 104mm pistons powering through short 64.7mm strokes.
Testastretta Evoluzione
The world-beating 1098 Testastretta Evoluzione needs little introduction. Debuting in 2007, it went on to form the basis of a motor that powered Ducati to Superstock and Superbike World titles that left the competition stunned. Now, its massive bore, short stroke and incredible torque powers Ducati’s most extreme naked and the results are equally as stunning.
Power & torque curves
Producing a ballistic 85lb-ft (11.7kgm) of torque and 155hp (114kW), the Streetfighter’s awesome 1098 power house fears nothing of the naked sports competition. The L-Twin, Testastretta Evoluzione engine gives both the best power-to-weight and the best torque-to-weight ratios in its class.
Vacural® crankcases
The Vacural® casting process used to make the Streetfighter crankcases ensures consistent and precise wall thickness and increased strength from absolute material purity while reducing weight an incredible 3kg (6.5lb) compared to those of the 1098 Superbike engine.
Elliptical throttle bodies
The Streetfighter engine is fed by MotoGP-derived elliptical throttle bodies which are equivalent to a diameter of 63.9mm. Representing a 30% increase in air flow over conventional throttle bodies, the elliptical shape contributes considerable a power increase. The Ducati 1098 engine was the first in the range to introduce this MotoGP technology for street use.
High-effieciency cooling
The Streetfighter’s power house is protected by twin coolant radiators, carefully curved in pure naked style for optimum performance and stunning with visual effect. The upper radiator is assisted by lightweight, high flow electric fan assemblies while the lower sits in the front of the belly pan, which also houses a highly efficient oil heat exchanger

Taking care of the rear of the ‘S’ is a single high-spec Öhlins unit fully adjustable in spring preload with full adjustment and highly engineered control of compression and rebound damping. The unit is also fitted with a ride enhancing top-out spring which helps maintain rear tyre contact under extreme conditions.
Marchesini 5-spoke wheels
The Streetfighter S reduces weight even further by using Y-shaped, 5-spoke wheels by Marchesini, forged and then machined in lightweight aluminium. The Streetfighter S wheels are finished in bronze.
Ohlins forks
The Streetfighter S pushes the spec way up with 43mm Superbike-spec Öhlins forks that have sliders treated in low-friction TiN. Fully adjustable in spring preload and precisely adjustable in compression and rebound damping, they ensure ‘S’ feeling and finesse when the fight gets rough.
EQUIPMENT
DDA ready
The instrument display also doubles as a control panel for the activation of the Ducati Data Analyser (DDA) system, which is available as an accessory from Ducati Performance. The bike has been built ‘system-ready’ for the data acquisition kit, which consists of special DDA software and a memory key that slots into a plug under the seat. The same plug also doubles as the connection for a handy new battery charger available as an accessory from Ducati Performance.
Stopwatch
The digital display is programmed with a stopwatch function that, when enabled, can be triggered by using the high-beam flash button and each recorded time stored in a memory. After your journey or track session, the times or lap times can be recalled from the memory and scrolled through by using the instrumentation buttons on the left-hand switchgear.
Fighter controls
The handlebars are gripped by beautifully shaped clamps that flow sleekly into the bar-risers. Symmetrically mounted, remote brake and clutch reservoirs are small, low and compact and feed slim, radial master-cylinders by Brembo to complete the clean and uncluttered controls arrangement.

"We decided to consolidate our presence here in Cologne because we believe in the importance of this exhibition event, which opens the European motor show season," stated Gabriele Del Torchio, President of Ducati Motor Holding, during the opening press conference. "Our presence at the show is proof of our commitment to customers in Germany and northern Europe, and underlines our aim to expand in Germany, which is the second most important market in Europe for Ducati. For this reason we decided to preview here some of the new products scheduled for 2011, such as the new additions to the Superbike family with the 848EVO and 1198 SP, and new liveries for the Monster and Streetfighter models."
Gabriele Del Torchio also commented on the results of the first eight months of 2010: "Despite a shrinking global motorcycle market, we have used Ducati's product policy and the quality of its distribution network to improve both our market share, now at 8.5%, and also to increase our sales by 5% compared to this period 2009."
A huge attendance is expected at the German show and visitors to the Ducati stand are sure to admire the innovative and ground-breaking Multistrada 1200, which made an immediate impact on the market upon debut in March 2010. The current model will not undergo any changes for 2011, confirming its proven design and high standard of quality. INTERMOT is also the first European event to celebrate the Multistrada's victory at the "Pike's Peak International Hillclimb", the famous annual race held high in the Colorado mountains, where riders have to quickly adapt to changing road surfaces. The Multistrada on which American, Greg Tracy, took victory has been specially flown in to Cologne from the US so that fans can share in this major celebration and see further proof of the Multistrada 1200's incredible versatility.
Important additions to the Ducati Superbike family are on show in an exclusive preview of the 2011 range, including the new 848EVO which boasts 140hp and is equipped with Brembo Monobloc callipers and steering damper. The performance-enhanced model celebrates the INTERMOT show by revealing a stunning new "arctic white" livery with sporty red wheels and red frame.
The standard 1198 is also ready to satisfy an ever more demanding market, with the addition of Ducati Traction Control (DTC), the Ducati Data Analyser (DDA) and the brand new Ducati Quick Shift (DQS) fitted as standard equipment on all versions. For 2011, the improved 1198 is joined by the exciting new 1198 SP, which enhances the previous 'S' version by rolling out equipped with DTC, DQS, DDA, Ohlins TTX rear suspension, slipper clutch and aluminium fuel tank in addition to the usual Ohlins front suspension, forged Marchesini wheels and lightweight carbon fibre components.
The 2011 Streetfighter S looks impressive in its new colour schemes of red with red frame or diamond black with racing black frame, both with black wheels. A black radiator cover on all versions completes the Streetfighter's aesthetic updates.
Enhanced comfort and safety, in addition to new colour schemes, headline the main updates to Ducati's naked icon, the Monster. The entry level 696 gets new 43mm Marzocchi forks and enhanced ergonomics, including 20mm higher handlebars and a new rear sub-frame designed to accept the user-friendly passenger grab-rail kit available as a Ducati Performance accessory. The Monster 696 presents the two new colour schemes of "dark stealth" and "stone white", perfectly complementing the new matte chrome handlebar finish. The Monster 796, which was launched in April 2010 as an early entry model year 2011, also adopts Marzocchi front suspension and continues its incredible success. Along with the Monster 1100, the 696 and 796 complete the 2011 range, confirming the family's status as a style and design icon, backed-up by 17 years of Ducati Monster heritage.
