At Aprilia there is another extremely fun toy pure and only for the circuit. The Italians have recorded the brand name X GP. There is a good chance that the X GP is the superlative of the X Extrema.
Since 2019, Aprilia has been surprised by friend and foe with super fat toys for the circuit. It was that year that Aprilia unveiled the RSV4 X during the very first Aprilia All Stars Event on the Mugello circuit, a presentation that had passed our nose because we had missed the flight to Firenze.
With a top power of 225 hp and a dry weight of 165 kilos, the RSV4 X was the most extreme Aprilia ever, if not the most extreme superbike at that time, with an unprecedented capacity/weight ratio of 1.36 hp per kilo. Aprilia had everything that was superfluous, mounted a lightweight carbon fiber racing tub and graphics of the 2019 RS-GP.
In addition, a lighter tank is mounted, racing switches are provided on the steering wheel, as well as countless parts milled from solid aluminum such as the clutch lever, the protector of the brake lever, the adjustable footrests and the carter protection. Marchesini forged magnesium wheels have also contributed to the reduction of the weight. Supercool were also the Brembo GP4-MS calipers, the same as on the RS-GP MotoGP machine.
The extra horsepower was borne by a Blueprint block (mounting parts with the most optimal play), inlet sealing axes with an aggressive profile, new valve springs, new stoter buses, a new Akrapovic exhaust system and a sprint filter element. Finally, Aprilia had applied an Ann (Aprilia No Neutral) gearbox, whereby the neutral to below first gear was moved.
The RSV4 X was made in a very limited edition of only 10 units. Only a few hours after the online reservation on factoryworks.aprilia.com was open was the purely and only € 39,000 cost for the circuit sold out. A year later, a Tuono V4 X followed, which was topped with the same sauce as the RSV4 X.
In 2022, Aprilia came with the RSV Xtrenta, where the Italians had gone one step further. According to Aprilia, the racing department had not used so much MotoGP technology as with the Xtrenta in terms of materials, components, electronics, attention to detail, but especially aerodynamics, which had already become crucial on a MotoGP machine at that time.
The RSV4 Xtrenta had the same whip of an aerodynamic wing as the RS-GP. In addition, Aprilia had provided the rear bridge with a so -called “Under Wing” wing. All parts of the carbon fiber tub were made by Pan Compositi, where the same processes as in the MotoGP were used.
Aprilia had also piped the power a little further to now 230 hp, while the color scheme was derived from the colors of the 125cc racer with which Aprilia in 1992 in the Road Race Grand Prix achieved the first of 54 world title. The edition was enlarged to 30 pieces, for a price tag of now € 50,000. This series was also sold out in no time.
In the past year, Aprilia came with a third Extreme RSV4, this time called the RSV4 x EX3MA (indeed, you pronounce that as Extrema). The EX3ma was an evolution of the Xtrenta, this time in the Perla Nera Color scheme as a tribute to the RS 250 with which Max Biaggi had become world champion for three years in a row. The same color scheme as that Aprilia had chosen the MotoGP Race on Silverstone, which was then dominated by 75 years Grand Prix History.
Also the RSV4 x EX3MA (where that figure 3 refers to the starting number 3 with which Biaggi always drove) was produced in a limited edition of 30 pieces, with the exclusive price in the meantime rising to € 80,000. This time, however, the sale went a little less smoothly, although Aprilia was still pretty proud that all 30 copies were sold out in ‘only’ 76 days.
By recording the brand name X GP, we now know that there is a fourth performance of the RSV4 circuit bike developed by the racing department. At the moment it is still coffee grounds to see what the specifications will be, but they will probably be higher than that of last year. And witness the name X GP will be a bit closer to the RS-GP25 with which Marco Bezzecchi won the British Grand Prix this year and became second in Assen and Brno. That was almost three 2nd places in a row if he had not crashed on the Sachsenring.
