This uncompromising sports machine is only available in the single-seat
version and is the perfect bike for all those who want to own a real
middleweight racer. The Testastretta engine is more highly developed than
ever before to maximise performance and minimise weight. Chassis components
have obviously been selected for maximum competitiveness on the track, and
special materials like magnesium, carbon fibre, and titanium abound to make
the 749R unbeatably light and mean.
The R’s engine has been specially developed for efficiency on the track.
It develops 121 hp at 10,500 rpm and 8.6 kgm of torque at 8,250 rpm.
By applying the knowledge gained on the racetrack, Ducati engineers have
created our highest performance middleweight Superbike ever, with fully
adjustable suspension, box-section aluminum alloy swingarm, and steering
damper. The 749 is as at home on the road as it is on the track and is
designed to offer an exciting, safe ride whatever the road conditions. A
sleek riding position blends man and machine perfectly.
At 108 hp, the Testastretta provides lightning acceleration out of
corners and incredibly smooth power delivery without putting stress on the
chassis set-up. Excellent torque (8.2 kgm at 8500 rpm), even at very low
rpms, guarantees superb performance while making the motorcycle easy to
handle in heavy traffic.
The 749R is driven by a mighty twin-cylinder Testastretta
engine created especially for racing. The 121 hp at 10,500 rpm has been
achieved through full race tuning, and shortening the piston stroke while
increasing the bore to 94 mm, up from the 90 mm of the 749 and 749s, thus
enabling the engine to run at higher rpm. The slipper clutch is also
racing derived and prevents the rear wheel from locking during track style
downshifting and heavy engine deceleration.
This Testastretta twin-cylinder engine has been created
using the best materials: titanium valves, valve retaining collets and
connecting rods, magnesium head covers and carbon fibre belt covers that
feature a ventilation system to enhance belt cooling. The feather-weight
crankshaft and high resistance aluminium alloy pistons complete the array
of top notch components.
One of the unique features of this model is the rear
suspension linkage, with flat rising rate as used on competition Ducatis,
that is suited to extreme track use and a single-seat set up. The lower
rising rate produces linear performance throughout the stroke with less
rigidity at high ranges, typical of high-speed cornering experienced on
the track. The suspension works in partnership with a fully adjustable
Öhlins rear shock absorber, with a shorter stroke than in the standard
version (down from 71 to 56 mm) and with a heavier spring, designed
especially for this motorcycle and its unique rear suspension.
This model is exclusively available as a single-seater and
is finished off with a numbered silver plate on the top yoke.
Features: 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 Öhlins 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.
