Finally, there's one highly original solution that may be missed at a glance: the tank, while apparently identical to that on the earlier versions, has been given a new base, which incorporates a new fuel pump.
There are also brand new colours, coordinating the stark black of the frame with three colour schemes for the tank and headlight shell: red, black, and an all-new pearl white. All the bikes 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, located in a more central position and wider than that of the previous SR machines. The end result of the S4RS Testastretta is nothing short of a dream ticket that satisfies the eyes and feel of even a casual observer even before they get a chance to get to grips with the astonishing performance.
Chassis
The heart of the most sports oriented and most powerful of all Monster machines is the super high strength steel tube trellis frame, which has been stiffened still further on this bike with a series of solutions that leave the dimensions unchanged. The frame is combined with the same single-sided aluminium swingarm found on all versions of the SR family. The main differences are to be found in the areas of suspension and brakes, which incorporate elements from even more exclusive series than those on the Monster S4R, which was the top of the range up to the end of 2005.
The front end is equipped, almost exclusively, with all the parts of the most prestigious and high performance 999 machines, starting from the Ohlins 43 mm upside-down fork with low friction TiN treatment to reduce sliding resistance and provided with all imaginable adjustment facilities for preload and damping. Also the two 320 millimetre discs represent the top of the production range, but in this case there are a few differences with respect to the axioms of the Superbike world, as can be found in the reservoir and master cylinder mounted on the variable section aluminium handlebar – specially designed for this version; the front brake callipers and handlebar-mounted master cylinders are of the radial type. The Ohlins trademark can also be found on the rear shock, which in this case hails from the most professional series and comes with a host of adjustment facilities for compression, rebound, and preload. The similarities with the chassis of the 999 family don't stop here but continue with the adoption of the Y spoke wheels which, apart from their undeniable aesthetic appeal, bring exceptional qualities of rigidity and low weight.
Equipped with an automatic choke, for this project the engine on the S4RS was given a dedicated oil cooler designed to offer optimum performance on a naked machine. Further details designed specifically for a more powerful and more exclusive Monster can be found in the airbox and the throttle body with IWP 189 injectors, not to mention the exhaust system with catalytic converter, which helps to bring the emission levels to within the limits imposed by Euro3 regulations, which is a pretty impressive feat for a 130 HP naked bike that is tagged to become a benchmark in its class from all standpoints.
The Testastretta – a milestone in the Ducati story.
The name of this engine (literally "narrow head") derives from the specific layout of the timing gear, which results in a reduced angle between the valves in the cylinder heads. The result is a compact and clean combustion chamber for the maximum combustion and compression efficiency: the flat crown pistons are perfect to ensure a smooth and linear flame front. The specific architecture of the heads, combined with a highly evolved electronic engine management system, guarantees optimal combustion at all speeds for smooth and effective power in all conditions.
