The Ducati 749R 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 fiber,
and titanium abound to make the 749R unbeatably light and mean.
The style of the 749R is extremely modern and almost identical
to that of the official Ducati racers. The R is also fitted
with the 2005 design fairings made from new high tech polymers.
A new manufacturing process has allowed Ducati to make the R's
fairing sections thinner and lighter than ever before. Though
it is designed to excel on the circuit, the 749R comes equipped
with elegant rear view mirrors and integrated direction indicators
that are not just stylish but quick and easy to remove for use
on the track. In line with Ducati tradition, all 749R motorcycles
are fitted with a numbered silver data plate on the steering
head.
Everything about the 749R's chassis is designed for maximum
efficiency on the track, from the trellis frame which allows
adjustment of the steering head rake angle to the brand new
aluminium alloy box section swing arm like that used on the
999 Factory in 2003. In addition to its uncompromising racing
design, this swing arm has a significantly better rigidity to
weight ratio than the standard swing arm. It also incorporates
Superbike type chain adjustment sliders instead of a conventional
cam mechanism. This means that chain tension adjustments do
not affect the suspension set-up in any way. The suspension
linkage is also brand new and features flat rate progression
like that previously implemented on Ducati Factory machines.
The new linkage system ensures excellent rigidity and far greater
precision under competition riding conditions. Better linkage
rigidity is achieved by use of a different spring, giving the
Öhlins monoshock a shorter compression stroke (56 instead
of 71 mm). Adjustments for spring preload, compression and rebound
are possible as usual.
The 749R has all the highly exclusive solutions for adjusting
ergonomics and riding position, including a 20 mm longitudinal
adjustment of the seat-tank assembly and footrest position adjustment.
The 749R has just two footrest positions instead of the five
on the other 749 models to comply with the rules of the world
Supersport championship which forbid removal of parts from production
bike frames. The footrest mounting plates have also been reduced
in size to give more room for the exhaust collector pipes which
are larger in diameter than those of the road-going models.
The front fork is of unbeatable quality. It is the latest, most
advanced Öhlins upside down unit and represents the absolute
top of the range of this famous Swedish manufacturer. The stanchions
are 43 millimetres in diameter and Titanium Nitride coated for
a smoother sliding action. Perfect fork action is also guaranteed
by innovative internal components. The fork is fully adjustable
and has a special bottom section designed to fit radial brake
calipers.
The 749R's calipers are triple bridge, four piston, four pad
units and operate on 4.5 mm thick disks that are themselves
fitted at an extended distance from the hub for improved cooling.
All brake and wheel components are race derived, including the
famous Brembo/Marchesini machine finished forged aluminium wheels.
The advanced finishing process used to manufacture these wheels
means that while they are 3.2 kilograms lighter than those of
the 749 and 749S, they offer the same excellent rigidity thanks
to the 10 points on the inside of the wheel to which the five
'Y' spokes are attached. (Conventional straight spokes only
have five anchor points.)
The 749R's engine is based on the same twin cylinder Testastretta
unit that powers the other members of the 749 range. The R's
engine, however, 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. These fantastic figures have been achieved by a series
of modifications, including a reduction in stroke and an increase
in bore to permit the engine to operate at higher revs. Owners
can also install the (optional) racing kit to increase these
figures even further, taking maximum power to a level unequalled
in the field of competitive motorcycle racing. The new "slipper"
clutch is also perfect for racing because it minimises rear
wheel slip during the hard downshifting frequently necessary
in competitive riding. Other important innovations, like the
racing profile cams and titanium valves and valve guides were
already introduced on the 2004 model.
The use of prestigious materials in the 749R's Testastretta
twin certainly does not end with the valve gear. The con rods
themselves are in titanium and the cylinder head covers in magnesium
alloy. Likewise, the timing belt covers are made of carbon fibre
and feature forced ventilation for better cooling. The list
of prestige components used on this engine ends with the special
super-lightweight crankshaft and high strength aluminium alloy
pistons. Despite its incredible power and torque the 749R's
power unit remains faithful to Ducati's environmentally friendly
engine policy. Even this fantastic twin is equipped with a catalysed
exhaust and conforms to Euro 2 emission control legislation.
