2019 Ducati Panigale V4 R Unveiled At EICMA

As you would expect, the Desmosedici Stradale R engine is a 90° V4. The cylinders are banked 42° rearward from horizontal for optimal packaging. The Twin Pulse firing order, which has the two left-hand cylinders fire closely together with the right-hand cylinders doing the same, will maintain the V-Twin-like sound that Ducati. The new forged steel, counter-rotating crankshaft is 1,100 grams lighter than on the Desmosedici Stradale, retains the 70° crank pin offset, and is mounted on brass bushings.

Molded aluminum pistons feature a single compression ring and an oil ring, which utilizes what Ducati calls “‘box in box’ technology: this contains both skirt height and below-chamber thickness, helping to reduce attrition and inertial loads while maintaining the necessary strength and stiffness.” Sliding those pistons in their cylinder bores are titanium connecting rods – each of which is 100 g lighter than the steel ones found in the standard Stradale. While the cylinder bores remain 81 mm, the stroke is bumped to 48.4 mm, yielding a 998 cc displacement. Compression ratio is a lofty 14:1.

Ducati tells us that the four camshafts feature dedicated profiles that operate the 34 mm titanium intake valves and the 27.5 mm steel exhaust valves with an increased lift. The valves themselves feature “titanium half-cones,” a feature typically only used by builders on racing machinery. The larger intake ducts in the cylinder heads have benefitted from fluid dynamic design.

Feeding those heads are oval throttle bodies that are the equivalent of 56 mm diameter units – an increase of 4 mm from the Stradale. Variable-height air intake horns further tune the airflow for engine conditions across a broader rpm range. Additionally, the atmosphere is cleaned by a free-flowing Sprintfilter.

So thorough were Ducati’s engineers, the oil pump was redesigned and the alternator was lightened, ultimately removing an additional 100 g from the engine’s weight.

The result of all this effort is a fire-breathing V4 that cranks out a claimed “221 hp (162 kW) at 15,250 rpm and 112 Nm of torque at 11,500 rpm (EU homologation values).” Furthermore, if fit with the full-racing Ducati Performance exhaust by Akrapovič, the claimed horsepower output jumps to 234 hp (172 kW) at 15,500 rpm. The rev-limit of the Desmosedici Stradale R is 16,000 rpm, and it shifts to 16,500 rpm in sixth gear.

While the Desmosedici Stradale R engine is still used as a stressed member, the Panigale V4 R front frame isn’t the same on the V4 S. First, it is lighter, but it also has its stiffness tuned to Ducati Corse specifications which was achieved through machining the sides – and, as a side benefit, reduces weight. Out back, the swingarm pivot height is adjustable over four positions which are set 2 mm apart. These changes highlight the track-focus of the Panigale V4 R.

Where the Panigale V4 was designed to be the ultimate bike for both street and track riders, the V4 R is laser-focused on the track. Consequently, the semi-active Öhlins suspension has been nixed for Öhlins professional units with mechanical adjustments. Based on Öhlins WSB racing forks, the fork is an exclusive to V4 R unit, the pressurized Öhlins 43 mm NPX 25/30 fork, featuring a titanium nitride slider treatment. According to Ducati, “Compared to a traditional system, a pressurized [system] minimizes the risk of oil cavitation, offering improved absorption of bumps, pits and ripples while ensuring excellent braking stability and support to give the rider better front-end ‘feel’.” The compression and rebound functions are in separate fork tubes, which utilize 25 mm and 30 mm pistons, respectively. The forks themselves were designed to save 600 g of weight compared to the V4 S.

The shock is an Öhlins TTX36 unit. Finally, an Öhlins steering damper was also fitted to the chassis. All of these units are mechanically adjusted for maximum tunability.

Wrapping all of that high-technology mentioned above is an aerodynamic package developed by Ducati Corse in conjunction with the Ducati Style Centre. This package includes: screen, nose fairing, and larger lateral fairings; efficient lateral vents for radiator airflow; and aerodynamic wings.

The front end of the bike features a higher, steeper angled windscreen to give the rider more protection around the helmet and shoulders at high speeds. Additionally, the fairing itself is 15 mm wider on both sides to keep the rider’s arms and shoulders out of the wind blast when in a tucked riding position.

The side fairings have been widened by a surprising 38 mm per side with the goal of helping the air to flow better around the rider while also “maximizing aerofoil efficiency.” Additionally, the fairing’s gills replace the venting on the Panigale V4 to help flow air through the air and oil coolers more effectively. According to Ducati, the “new vents increase air through-speeds on water and oil radiators by 6% and 16% respectively.”

OEM wings are now officially a thing in 2019. The Panigale V4 R’s wings take a step away from the styling of those on Ducati’s current MotoGP bikes and, instead, harkens back to the GP16 generation bike. According to Ducati, the V4 R’s wings are more efficient than those currently utilized in MotoGP.

Ducati describes the wings thusly: “These monoplane single-element wings have a trapezoidal layout with a tapered profile from root to tip. Wing performance has been improved thanks to the insertion of the longitudinally arranged strake and the winglet which ‘insulates’ the airflow over its surfaces.”

The result of the combination of the fairing and wing design is an additional 66 lbs. of downforce at 168 mph! This downforce will reduce front wheel “float” and the tendency wheelie at high speeds. Ducati says that the wings improve stability under braking while turning into a corner. Additionally, the intervention of electronic rider aids is also reduced thanks to the new wings. Finally, Ducati claims the functional cost of the wings is fairly low, namely “a small increase in steering torque caused by the heightened stability.”

Naturally, these controls can be adjusted from the left grip, via the TFT display.
