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.
