Aprilia 1100 RSV4 X-GP 2026 — Specifications

Fourteen days. That’s how long it took for the thirty examples of the RSV4 X-GP to find buyers, at a price of €90,000 each excluding taxes. Few will truly be surprised. Since the engineers at Noale launched their Factory Works program in 2015, each new iteration of the X lineage has pushed the boundary between road bike and competition prototype a little further. With the X-GP, that boundary has practically disappeared.

The official pretext is the tenth anniversary of the RS-GP, the machine entered in the world championship. But behind the celebration lies a much more radical intention. What Aprilia is offering here is a Superbike disguised as a MotoGP, designed for the rider who wants to feel what Jorge Martin or Marco Bezzecchi experience under their grips on race weekends. The delivery incidentally borrows the colors of their official team, and that is no coincidence. Visually, the X-GP turns its back on the standard RSV4 on which it is based. The front section, inherited from the ex3ma, remains recognizable with its multi-layer carbon fiber fairing signed PAN Compositi and its aggressive winglets. The rear, on the other hand, has been completely redesigned to adopt the tail of the Grand Prix RS-GP, a massive block loaded with side wings borrowed from the RS-GP25 of the current season. The diffuser under the nose loads the front of the motorcycle to limit the need for traction control on corner exit, while the side panels play with ground effect to generate downforce. This is genuine active aerodynamics, not the style for a marketing brochure.

The 65° V4 engine with a displacement of 1,099 cm3 also receives its share of intensive treatment. Compression ratio increases, the intake trumpets go to a racing version, and a Spintfilter air filter takes center stage. The result is 238 horsepower at 13,750 rpm, eight more than the ex3ma, and a redline pushed to 14,100 rpm. Peak torque is 131 Nm at 11,750 rpm. These figures don't tell the whole story. What matters is the distribution of this power in a double-spar aluminum chassis that weighs 165 kg when wet, eight kilograms above a current MotoGP prototype. The difference is made in the suspension, with a 43 mm Öhlins FKR fork and a TTX shock absorber whose settings are derived directly from the World Championship. Brembo brakes with GP4-MS calipers on 330 mm T-Drive discs complete the package. Forged magnesium Marchesini rims, lighter than standard aluminum but less than the initially considered carbon, complete a set whose mechanical coherence is difficult to fault.

APX electronics manage traction control, anti-wheelie, engine braking, and power delivery, with an integrated GPS module for data acquisition. This is no longer the realm of an advanced road bike. This is the tooling of the professional rider. The delivery of the machine includes a Yashi laptop preloaded with the ECU management software, heated covers, titanium workshop stands, and a certificate of authenticity as an NFT. The buyer can also visit Aprilia’s racing department in Noale. The motorcycle is received as factory equipment, not as a purchase from a dealer.

The only point on which one could quibble is this limitation of use. The RSV4 X-GP is not homologated for any championship. It is also not a road bike in the practical sense of the term. It is a track object absolutely consistent for the 30 people who wrote the check, and a fascinating curiosity for everyone else. Faced with a Ducati Panigale V4 SP2 or a BMW M 1000 RR, which remain machines accessible to competition with homologation, the X-GP plays in a category of its own, that of collector's items that can be ridden. Its true competitor is not a Superbike. It’s a ticket to enter the paddock.
