RSV4 X-GP

The RSV4 X-GP is an aerodynamic masterpiece, its design directly derived from the RS-GP25. For the first time ever on a production-based motorcycle, it introduces leg wings and tail wings, technology developed and patented exclusively by Aprilia Racing and seen only a few months ago on the RS-GP25. These innovations add significant downforce during braking and cornering.

Completing the aero package are a uniquely shaped front wing, an under wing, and cornering wings.

Equipped with ground-effect aerodynamics, also patented by Aprilia Racing, the RSV4 X-GP features side fairings designed to reduce air pressure between the bike and the asphalt while leaned over, generating downforce that presses the bike firmly to the ground.

The entire fairing is made of carbon fibre by PAN Compositi, using the same processes employed in MotoGP. This construction increases vertical load by five times on the straight, enhancing stability and precision while reducing wheelies, and triples the load in corners, ensuring exceptional grip and feedback.

Another feature taken straight from MotoGP prototypes is the structural carbon-fibre seat support, also crafted by PAN Compositi. It integrates structural, aerodynamic, and design functions in a single element.
An additional refinement is the sandwich carbon layup, a special layering technique designed to maximize lightness while preserving rigidity. This increases rear-tyre feedback, giving the rider a more direct connection to the bike’s behavior.

Enhancing the package are the twin-outlet SC Project exhaust in full MotoGP style, designed to maximize performance and deliver a true racing sound, and a special livery inspired by the RS-GP25, a tribute to Aprilia Racing’s latest MotoGP evolution.

The RSV4 X-GP is a true MotoGP-style racing machine. Its legendary 65° V4 engine, 1,099 cc with SBK racing specifications, has been tuned by Aprilia Racing’s engineers to produce a staggering 238 hp at 13,750 rpm (revving up to 14,100 rpm) and 131 Nm of torque at 11,750 rpm. These figures are achieved through dedicated tuning, including a higher compression ratio, a Sprint Filter high-permeability racing air filter, dedicated intake trumpets, and a titanium SC Project exhaust system with twin pipes and compensator, along with an STM dry clutch.

All active electronic systems are managed by the APX ECU developed by Aprilia Racing, the latest evolution of the same unit that powered RSV4 to WorldSBK titles with Max Biaggi.
This ECU uses racing-level strategies identical to those deployed in competition, with fully customizable parameters to suit riding style and track conditions. It also features complete **data acquisition for performance analysis.
The APX system manages wheelie control, traction control, engine braking, and power delivery, gear by gear. A built-in GPS module is also included. Each RSV4 X-GP comes with a dedicated Yashi laptop preloaded with the software for ECU management and fine-tuning.

Every detail of the RSV4 X-GP bears Aprilia Racing’s racing DNA: carbon-fibre mudguards, Jetprime racing switchgear, Spider adjustable rearsets, clutch lever, fuel cap, engine case and brake lever guards, all machined from billet aluminium. The steering plate is CNC-machined and individually numbered.
Cooling is optimised with oversized WSBK-derived radiators, while the final drive features a titanium sprocket, lightweight PBR front sprocket, and an RK 520 racing chain.

The celebrated aluminium dual-beam frame, a hallmark of Aprilia’s chassis expertise, is enhanced with Öhlins mechanical suspension featuring a dedicated setup. At the front, a pressurized Öhlins fork is paired with a Brembo braking system: radial 19x16 master cylinder, monobloc GP4 MS calipers, Z04 racing pads, and 330 mm T Drive discs. At the rear, braking is handled by a caliper with a nickel-plated finish.
The RSV4 X-GP rides on forged magnesium Marchesini wheels, shod with Pirelli Superbike slicks (SC-1 front 125/70, SC-X rear 200/65) – the very same tyres used in WorldSBK.
