Monster S4RS Testastretta
The S4R S is characterised by a Ducati Trellis frame and black swingarm, a front end derived from the 999, and by the Y-spoke wheels. It has also a the triangular oil cooler and numerous carbon fibre parts, including the silencer cover, front mudguard, cam belt covers, exhaust system heat shield, radiator covers and the side panels. As proof of the painstaking attention to the tiniest details, even the cooling circuit ducts are now forged in aluminium rather than moulded in rubber.
Two attention-grabbing vertically stacked silencers in aluminium, complete the overall super-aggressive but beautifully styled statement of performance and technology.
The same attention to detail was dedicated to the cockpit which is equipped with the same instruments as the S2R but with dedicated model graphics. Additional details are a little easier to miss, like the fuel tank which, while apparently identical to that on the earlier versions, has actually been given a new base which incorporates a new fuel pump.
Three different colour schemes for the tank and headlamp fairing are Ducati red, black, and an all-new pearl-white. All schemes are distinguished by the racing stripe (white for the red tank, red for the pearl white, and grey for the black) that slashes the machine from fore to aft and is located in a more central position and wider than that of the previous SR machines.
Chassis
One of the most beautifully engineered components on the most powerful of all Monsters is the super high strength steel tube Trellis frame. Stiffened still further on this model the frame is combined with the same single-sided aluminium swingarm that is found on all versions of the SR family.
The main differences are to be found with the suspension and brakes. The front end is equipped with parts taken from high performance 999, starting from the Öhlins 43mm upside-down forks, with low friction TiN treatment to reduce sliding resistance, which are fully adjustable for preload and damping.
Two 320mm discs and radially mounted calipers represent the top of the range front brake solution fed from radial master cylinders mounted on variable section aluminium handlebars. An Öhlins rear shock, fully adjustable in compression, rebound, and preload and Y-spoked wheels with exceptional rigidity and low weight complete the chassis set-up.
Engine
The S4R S Testastretta producing a massive 130hp. This engine needs no introduction, it has won fame and respect on the circuits of the World Superbike Championship and in so doing represents the maximum technological expression of Ducati engineering : a twin-cylinder engine able to beat the power of its massive rival four-cylinder competition.
.
For the S4R S the engine was given a dedicated oil cooler designed to offer optimum performance. Further details designed specifically for the powerful Monster can be found in the airbox and throttle bodies with IWP 189 injectors. The exhaust system with catalytic converter brings emission levels to within Euro 3 regulations.
The ‘Testastretta’ represents a milestone in the Ducati story, its name translated literally meaning ‘narrow head’, and derives from the specific layout of the timing gear, which is characterised by a narrow valve angle enabling a much more compact cylinder head. The result is a clean combustion chamber for maximum combustion and compression efficiency. The flat crown pistons are perfect to ensure a smooth and linear flame front and the specific architecture of the heads, combined with a highly evolved electronic engine management system.
MONSTER S4R Testastretta
Founder of the SR family, the S4R takes on a very important role alongside the ‘S’ version which is the current performance and equipment leader of the Monster range. 
Equipped to catch the attention of the most performance hungry ‘Ducatisti’, the S4R Testastretta is more than capable of fulfilling its important role in the new Ducati 2007 range.
The new S4R Testastretta is now available in two new colour schemes, Titanium with central black stripe, and traditional Ducati red with central white stripe. Both colour versions have a red Trellis frame with black swingarm which matches the new Showa front fork sliders. 
Chassis
The fully adjustable Showa upside-down forks provide a perfectly balanced front-end while the rear is fully adjustable with a Sachs piggy back reservoir shock. A vitally important feature of the rear suspension system is the ability to adjust rear ride-height independent of spring pre-load, enabling the rear-end to be adjusted to an exact ride-height set-up without changing the shock’s other settings thanks to the adjustable push–rod.
Radially mounted Brembo front brake calipers giving the front-end a decidedly race-orientated look.
Engine
The S4R has a massive increases in power from 117hp of the previous engine, to 130hp of the Testastretta and continues to feature twin-stacked silencers, aluminium Trellis single-sided swingarm, sporty headlamp fairing, exclusive paint schemes and high quality suspension.

 crazybatman (20-11-2006): rien à dire, toujours aussi belle, indémodable.
toutefois deux reproches: cette horrible gamelle de collecteur, et l'ensemble compteur/compte-tour vraiment pas terrible pour une telle moto.
là pour le coup Ducati devrait peut-être allez copier chez les voisins (anglais?)
