Ducati 749R - 2005
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 Íhlins 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 Íhlins 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 callipers. The 749R's callipers 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.
