DUCATI 749 R

Ducati chose the renowned Valencia racetrack in Spain as the proving ground for the 749R’s first on-track tests and 2004 Supersport Team Ducati Breil launch.


From February 22nd to 24th Testastretta horsepower will be unleashed in Valencia, while the following week will witness the opening of the 2004 World Superbike and Supersport Championships.

The new 749R completes the Ducati Superbike range and marks Ducati’s return to the World Supersport championship. The bikes that take part in this championship are purely derived from production models. Very few modifications to the chassis and engine are allowed. The 749R was designed with a single purpose: to race on the track. It’s a true racing bike and, with a street legal homologation and plate, it can serve up thrills off-track as well.

Once again it is the technology that makes all the difference, the high quality standard of each individual component, and the ability to transfer racing know-how to a bike destined for the public. Passion and a confidence-inspiring-ride are in the 749R DNA.

The 749R needs no introduction: the twin-cylinder short-stroke Testastretta engine (to reach higher revs) is filled with racing components: from the deep sump to the slipper clutch, from titanium valves to the timing belt cooling system, the 749R achieves maximum performance with no loss of reliability.

Taking a look at the rest of the bike, things only get better: full carbon fiber fairing, aluminum forged wheel rims, radial front brake calipers and a brand new rear swingarm, very similar to that found on the 999R race bike which dominated the World Superbike championship: a light and stiff double-sided structure welded from cast and pressed aluminum parts.

The 749R, born to race in the World Supersport championship, will be available at your Ducati Dealer, beginning the end of February, 2004.
