Aprilia RSV4 X ex3ma '2024

20 September 2024

Aprilia Racing continues its pursuit of the highest technology with the RSV4 X ex3ma, the most sophisticated RSV4 ever produced. This is the fourth chapter of a unique project that began in 2019 with the RSV4 X, followed by the Tuono X, and progressed in 2022 with the more advanced RSV4 X Thirty. These truly unique models, marked by an ‘X’, represent the pinnacle of technology and performance available to the public.

The Aprilia RSV4 X ex3ma marks a direct link with MotoGP, as it is the first and only bike available for public sale equipped with ground-effect aerodynamics. This highly sophisticated technology, entirely developed and patented by Aprilia Racing, was previously exclusive to the RS-GP 24, which competes in MotoGP.

The specific shape of the moulded fairing on the flanks exploits air pressure between the ground and the bike during cornering, increasing grip. The entire aerodynamic package, derived from MotoGP, includes the newly designed front wing, the under wing (commonly known as the ‘spoon’) under the swingarm, and the cornering wings on the lower part of the front mudguard. The fairing is made entirely of carbon fibre, crafted by PAN Compositi using the same techniques as MotoGP. Compared to the already advanced X Trenta, it increases vertical air pressure fivefold in a straight line, improving stability and precision while reducing wheelies. In corners, it triples the downforce, significantly enhancing grip.

The special Perla Nera livery draws inspiration from Aprilia’s heritage and the mythology of motorbike racing. The glossy black and graphic finish of the RSV4 X Ex3ma is a clear tribute to one of the iconic bikes in the sport’s history, the RS 250, on which Max Biaggi won three consecutive world championships from 1994 to 1996 in the 250cc class. It’s no coincidence that Aprilia Racing chose this livery for the recent Silverstone race. To celebrate 75 years of MotoGP, each manufacturer raced in its most iconic colours.

The data sheet describes a true racing bike with no compromises. The legendary 65° V4 engine, with a displacement of 1099 cc, has been fine-tuned by Aprilia Racing’s engine specialists, delivering 230 hp at 13,500 rpm (with a maximum speed of 13,900 rpm) and 131 Nm of torque at 11,000 rpm. This performance is achieved through specific tuning of the V4, which includes a higher compression ratio, a high-permeability Sprint Filter air filter, and an SC Project exhaust system with titanium headers and twin tailpipes.

The evolution of the Aprilia RSV4 X ex3ma goes beyond aerodynamic and engine innovations—the electronic systems also elevate this superbike to new levels of technology and performance. The ECU that manages all the active electronic controls is Aprilia Racing’s renowned APX, an exclusive component and the latest evolution of the system used in the WSBK World Championships won by Biaggi and the RSV4. This ECU incorporates the same operating strategies as the RSV4 race models and includes an integrated data acquisition system, utilising specific sensors essential for fine-tuning vehicle dynamics. In particular, the APX system enables precise calibration of wheelie control, power, traction control, and engine braking for each gear. The rider can adjust these parameters on the move, using the dedicated push-button panel, or during bike setup via an editable interface software on the included laptop. An integrated GPS further enhances the APX system.

A Yashi laptop is provided with the bike to manage the ECU software effectively.

The multi-titled twin-spar aluminium frame, long a symbol of Aprilia’s mastery in crafting agile and precise frames and suspensions, is enhanced by Ohlins mechanical suspension featuring a custom setup, including a sophisticated pressurised fork. The Brembo braking system includes a 19x16 radial pump at the front end,GP4 MS billet callipers with Z04 racing pads and 330 mm T Drive brake discs, while the rear brake disc is equipped with a calliper featuring surface nickel plating.

The Aprilia RSV4 X Ex3ma has carbon fibre rims, which reduce weight and unsprung mass, enhancing handling, acceleration, and braking performance. These rims are fitted with the same slick tyres used by Pirelli in the Superbike World Championship: SC1 (front, 125/70) and SCX (rear, 200/65).

Every detail showcases the meticulous craftsmanship that Aprilia Racing has invested in this model,​ including the carbon fibre mudguards. The right handlebar switch is a racing component by Jetprime, while the adjustable footpegs, clutch lever, steering plate (engraved with the model’s serial number), tank cap, engine casing, and front brake lever guards are all crafted from billet aluminium. The oversized water and oil coolers, made to racing specifications by Taleo Tecnoracing, further enhance performance. The final drive features a titanium crown, a lightened sprocket by PBR, and an RK racing chain.
