All Duels - Duel Tuono V4R APRC Vs Speed ​​Triple R: roadsters with big Rs - Technical update on Aprilia Tuono V4R APRC

Equipped like racing motorcycles, the ultra sporty roadsters reach new heights in terms of pure performance. The proof with this MNC Duel between two European motorcycles that send the R: Aprilia Tuono V4 R APRC and Triumph Speed ​​Triple R !

Technical update on Aprilia Tuono V4R APRC

Modeled on the RSV4, the Aprilia Tuono V4R APRC is propelled by a 4-cylinder V at 65 ° of 999.6 cc. Deflated to "only" 167.3 hp (180 hp for the Hypersport), this hyper compact and highly compressed unit (13.1: 1) outputs 111.5 Nm of torque at 9500 rpm in free version.

To promote revival, Italian engineers lengthened the intake ducts by 20 mm and blocked its trumpets – variable length on the RSV4 – in the high position. With the same objective, the crankshaft has been made heavier, the first three gears of the extractable box have been shortened and the distribution, exhaust and injection have been reworked..

Extremely modern, the Aprilia V4 houses state-of-the-art electronics. Free of any form of cable, the "Ride-By-Wire" type accelerator is a potentiometer connected to the electronic control unit (ECU). It acts on the injection after a cross-analysis between the requested order and the information communicated by an army of sensors (angle of the motorcycle, speed, engine speed, gear engaged, etc.).

As on the RSV4, there are three injection maps that can be selected by pressing the starter on the right stalk: "Track" (track), "Sport" and "Road". With the first "mapping", the arrival of the cavalry is instantaneous, almost brutal, which tends to accentuate the jolts sometimes felt on the gas net..

In "Sport" mode, the 167.3 hp are distributed more progressively over the first three reports, while the "Road" map cuts the maximum power by about 25%. In the French version, the differences are obviously more tenuous … The "Sport" mode nevertheless remains the most comfortable, while the lower power offered by the "Road" mode is useful in the wet.

Very sophisticated, the Tuono V4 R now carries the APRC (Aprilia Performance Ride Control) system as standard, the version without this arsenal of electronic aids no longer offered in concession (read). The APRC includes an AQS (Aprilia Quick Shift) shifter, an AWC (Aprilia Wheelie Control) anti-wheeling adjustable on three levels and disconnectable via the "Mode" button, and finally an ATC (Aprilia Traction Control) anti-slip.

Ultra fast, the action of this traction control can be configured while driving, without releasing the throttle or disengaging. You just have to press the "+" and "-" commands (stolen from Mana) to vary its intensity at any time. ATC has eight notches ("1" being the most intrusive) and can be disengaged for "freestyle" enthusiasts….

Finally, the APRC also includes ALC (Aprilia Launch Control) starting assistance, a new system directly from MotoGP: configurable in three positions, this function is activated by pressing the "+" and "- paddles for 3 seconds. ". Once the ALC is activated, all you have to do is put on some heavy gas, let go of the clutch bluntly, and you’re off to a great Dani Pedrosa start with the front wheel level with the ground. !

The ALC has its own skating and wheeling management. It is deactivated when changing to third gear or above 160 km / h. Like all the other aids, it is informed by the Ride-by-Wire, two inclinometers and the speed sensors which come in the form of toothed crowns attached to the wheels..

The intervention of all this electronics is at the level of the power supply via the opening of the injection butterflies and the ignition advance. Side cycle, the Tuono V4 R APRC uses the very light frame (10.1 kg) double aluminum beam of the RSV4, as well as its swingarm cut in the same metal.

The geometrical values ​​evolve for more stability (the wheelbase goes from 1420 mm to 1445 mm), while the weight increases slightly: 183 kg dry for the Tuono against 179 for the RSV4, despite the less fairings and the announced rims lighter than 2 kg….

The fully adjustable suspensions come from Sachs: the inverted 43mm fork is treated with titanium nitride to reduce friction, while the mono-shock is equipped with a separate nitrogen cylinder which limits the effects of emulsion.

The radially mounted 4-piston calipers are signed Brembo and surround 320mm brake discs. The rear is a single-disc type with a two-piston caliper. Delivered as standard in 190/50/17 at the rear, the Tuono is also approved in 190/55/17 or in 200/55/17, which allows its behavior to be modified according to individual tastes..
