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.
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.
Wheels10-spoke wheels in lightweight aluminium keep the overall motorcycle weight down and maintain an all-important 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 and the 'S' in bronze with both models rolling out on Pirelli 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 an incredible 3kg (6.5lb) compared to those of the 1098 Superbike engine.
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 the distance between service intervals to increase to 12,000km (7,500 miles) 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 L-Twin sound synonymous with raw, Desmo power.
Lighting
The new 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 sophisticated pearl white set against a black frame and subtle graphite grey 10-spoke wheels, the Streetfighter S positively seduces in red and menaces in midnight black with carbon fibre front fender and cam belt covers contrasting superbly against the bronze finish of the frame and Y-shaped, 5-spoke wheels.
