For those focused directly on competition, the 749R is the ideal solution. It is a perfect racing machine, with a Testastretta series engine and chassis specifically developed to ensure top competitiveness on the racetrack. The considerable use of special materials, from magnesium to carbon fiber to titanium, make this motorcycle extra-light and extremely effective.
Every 749R is "signed" with a numbered silver plate on the steering head, which adds yet another exclusive touch to one of the most original bikes on the current worldwide motorcycling scene. The front suspension is also very high quality: an Öhlins upside-down fork with tubing 43 millimeters in diameter, with titanium nitride treatment for smoother sliding. In addition to being fully adjustable, the fork has a special foot to allow radial fastening of the brake calipers.
The twin-cylinder of the Testastretta series was also developed to encourage the racing use of the 749R. The 116 HP at 10,500 rpm, and 8.16 kgm at 8,500 rpm are the result of a long process that begins with shortening the stroke and increasing the bore. The new slipper clutch, which has been specifically developed for racing use, stops the rear wheel locking up under extreme braking conditions typical of track riding. Also made of titanium are the connecting rods, while the head covers are made of magnesium and the belt covers are carbon fiber, equipped with forced ventilation to aid in cooling.
The use of titanium in the production of the valves represents a totally new innovation for Ducati motorcycles. In fact, the 749R is the first Ducati ever to make use of such technology. Titanium valves reduce weight and the mass of moving parts significantly, resulting in a reduction of reciprocating force and stress on the valve train. Valves of lower mass being actuated by the same profile cam results in higher valve-acceleration and therefore safely permits the use of a cam using a competition profile.
