2006 Ducati 749R

Ducati 749R Ducati 749R

Just a glance is enough to recognise a no-holds-barred solo machine, designed expressly for use on the racetrack at the highest level of competition. The engine hails from the Testastretta series, while the solutions adopted for the chassis equipment are among the most evolved and extreme in the world of Superbikes, meeting with the approval of the most discerning racers. The 749R is built making ample use of prestigious materials such as magnesium and titanium to achieve the lowest possible overall weight.

Style;

Original and totally aggressive, like all Ducati Superbikes, the 749R adds a numbered silver plaque on the top fork crown, making each machine absolutely unique. But apart from all the sheer guts it delivers on the racetrack, the most sports-oriented of the 749 machines is produced to ride on the street too, complete with mirrors with integral turn indicators. Apart from their elegant styling, these unique turn signals have the advantage of being quickly removable when the bike is being prepared for a race.

Chassis ;

In order to enable the best possible control of the performance available from the powerful Testastretta twin, each chassis element of the 749R was selected and tested with the aim of offering the maximum performance in competition conditions. That's why, alongside the elements shared by all bikes in the range, notably the trellis frame with adjustable steering head rake, there are several other details that have come straight from the race department. The box-section aluminium swingarm is structurally very similar to the unit installed on the 999s ridden by Toseland, Laconi and Lanzi or the Supersport raced by Nannelli, with clear benefits in terms of weight and stiffness. The swingarm is combined with a chain tension adjuster that uses sliders instead of cams, thereby avoiding the undesired effect of changing the height of the rear end of the machine and consequently the set-up when making adjustments to the final drive. The similarities of the rear suspension with the official race 999s continue with the shock linkage with flat progression, absolutely ideal to obtain the stiffness needed to obtain the necessary precision when riding at race speeds. The performance of the rear end is aided by the Íhlins shock, with fully adjustable hydraulic damping and equipped with a dedicated spring and more limited travel: 56 millimetres compared to the 71 millimetres of the other versions. Like the rear monoshock, also the fork is an upside-down configuration, with 43 mm sliders and, like all front suspensions installed by Ducati on its top-level machines, the sliders are TiN coated to ensure extremely low friction. Like the rear shock, the fork is fully adjustable and equipped with a special bottom lug for radial attachment of the brake callipers. These components were clearly designed for race applications, as were the brake system and wheels. The brakes feature 4.5 mm thick rotors and radial callipers with four pistons and the same number of pads, while the lightweight alloy wheels are Brembo/Marchesini units with five Y-spokes in forged and machined aluminium, offering a weight saving of 3.2 kg compared to a pair of conventional wheels, without sacrificing rigidity.

Like all single-seater versions, the 749R provides fore and aft adjustment of the seat-tank combination. It's also possible to alter the position of the footrests, but with respect to the other versions the choices in this case are two rather than five. This decision is based on the rules of the World Supersport Championship, which disallow the removal of any parts welded to the original frame. To allow the passage of the oversized diameter racing exhaust manifolds it was therefore decided to use smaller footpeg brackets, which limit the adjustments.

Powerplant;

The effects of a reduced stroke and increased bore, which allow the Testastretta twin to achieve higher revs, are clearly evident. On the standard equipment package the engine offers 121 HP at 10,500 rpm, with torque of 8.6 kgm at 8,250 rpm. These values can be boosted still further with the installation of the optional racing kit. This model features the use of prestigious materials such as titanium for the valve gear, magnesium for the head covers, and carbon fibre for the timing belt covers with forced ventilation. Every detail is engineered to achieve the maximum efficiency when entering and exiting bends. Consider, for example, the super lightweight crankshaft and high strength aluminium alloy pistons which serve to increase power output, and also the slipper clutch, which prevents rear wheel chatter under conditions of intense engine braking. Even though it affords performance levels that are at the very pinnacle of the category, the Testastretta twin mounted on the 749R is equipped with a catalytic exhaust system and consequently has emission levels that easily comply with stringent Euro2 standards.
