Aprilia Rolls Out the Most Powerful Superbike with Sprint Filter

On the occasion of the Grand Prix of the United States, Aprilia Racing unveiled the Aprilia X 250TH, a special edition born out of the cutting-edge technological excellence developed in MotoGP. The new Aprilia X 250TH was built to celebrate the 250th anniversary of the signing of the United States of America’s Declaration of Independence, which took place on July 4th, 1776.

For this reason, the decision was also made to earmark 25 of the 30 units for the U.S. market, with the remaining bikes available for the rest of the world, and to dedicate the spectacular “Stars and Stripes” livery inspired by the colors of the American flag.

On a technical level, Aprilia Racing has taken another step forward with the Aprilia X 250TH. In fact, it is the first and only bike on the market fitted with carbon brakes – the same ones used in MotoGP. This feature makes the X 250TH the bike on the market capable of expressing the same braking power as the Aprilia RSGP ridden by Marco Bezzecchi and Jorge Martín.

Furthermore, on the aerodynamic front, the latest-generation MotoGP-derived seat wings have been updated. These elements confirm the “X” brand’s vocation to represent the most advanced point ever in the connection between a factory bike and a MotoGP prototype.

Aprilia Racing thereby consolidates its internationally renowned “X” brand with the Aprilia X 250TH, the sixth generation of a unique project to the world, launched in 2019 with the RSV4 X, followed up in 2020 with the Tuono X, in 2022 with the RSV4 X Trenta, in 2024 with the RSV4 X ex3ma, and in 2025 with the RSV4 X-GP. Exclusive models distinguished by the “X” which represents the absolute pinnacle of excellence that can possibly be aspired to in a bike, sold to the general public.

BRAKING SYSTEM
An absolutely distinctive element of the Aprilia X 250TH is the Brembo carbon-carbon braking system, unique in its kind for a factory bike. The system employs carbon brake discs – the same ones used in MotoGP – with a diameter of 340 mm, high mass, combined with carbon pads and a billet aluminum caliper with cooling fins. The system is completed by the rear brake disc, which is gripped by a nickel-plated caliper.

The use of carbon discs translates to half the weight of traditional steel discs, improving the bike’s overall handling, while the carbon pads weigh about one-third less than sintered pads. At the same time, it ensures consistent performance even under extreme use, bringing the riding experience and braking power even closer to those of MotoGP prototypes.

AERODYNAMICS
Aerodynamics are another distinctive element of the Aprilia X 250TH, an area in which Aprilia Racing confirms its status as a pioneer in MotoGP. In fact, the lines of the new X are inspired by the RS-GP, especially in the rear design, faithfully replicating the airflow. The aerodynamics package features advanced, MotoGP-derived solutions, including seat wings – Aprilia Racing’s proprietary technology – and tail wings, which appeared for the first time on the RS-GP25. The combination of seat wings and tail wings adds aerodynamic load during braking on corners, as well as the rear wing, the under wing and the cornering wings.

Another distinctive element is the carbon structural saddle support, made by PAN Compositi, with “sandwich structure” processing. This is a specific way of arranging the carbon fibers to make them extremely lightweight while still maintaining rigidity.

All of these elements make the vehicle’s rear-end dynamics even more similar to those of the racing prototype, increasing grip and ensuring a more direct link between rear-tire performance and the rider’s sensations. Completing the package is the SC Project titanium MotoGP replica double exhaust, designed to maximize performance and deliver a racing sound.

The Aprilia X 250TH also includes an advanced ground-effect aerodynamic system, developed and patented by Aprilia Racing. The design of the side fairings generates downforce when the bike is leaned over, increasing grip and stability in cornering.

All the fairings are made in carbon by PAN Compositi with the same procedures used for the MotoGP bikes. The vertical load on the straightaway is five times that of the Aprilia RSV4, increasing stability and reducing wheelies, whereas in leans there is three times as much load, all to the advantage of grip in corners. Highlighting its exclusive nature is the “Stars and Stripes” livery, which features the colors of the American flag.

ENGINE
The Aprilia X 250TH is equipped with a 1099 cc 65° V4 engine developed by the Racing Department with SBK racing specifications. Maximum power reaches 240 HP at 13,750 rpm (max regime at 14,100 rpm), with maximum torque of 131 Nm at 11,750 rpm.

This performance is achieved thanks to a targeted evolution of the V4 engine, which includes increased compression ratio, a Sprint Filter high-permeability racing air filter with racing-spec airbox intake trumpets, an SC Project titanium dual-pipe exhaust, and an STM dry clutch.

In a project where every detail is designed to push boundaries, Sprint Filter plays a decisive role in optimizing engine breathing. Thanks to its advanced filtration technology, high permeability, and exceptional airflow capacity, our air filter allows the 1099cc V4 engine to deliver its full potential -reaching an astonishing 240 horsepower. Maximum air permeability, combined with consistent performance under extreme conditions, makes Sprint Filter an essential element in achieving such extraordinary results.

ELECTRONICS
Electronics management is handled by the Aprilia Racing APX control unit, a direct evolution of the systems used in the WSBK Championship that Biaggi won astride the RSV4. It is a unit with fully adjustable parameters to adapt to riding styles and track conditions. The APX system allows management of the front lift mitigation feature, power, traction control, and engine brake for each gear, and is complemented by an integrated GPS system.

CHASSIS ARCHITECTURE
The Aprilia X 250TH comprises an aluminium double trellis frame, combined with mechanical Öhlins suspension with dedicated setup, including the pressurized fork. The setup is completed by forged Marchesini magnesium rims, shod with Pirelli slicks used in the World Superbike Championship.

The level of finishing reflects Aprilia Racing’s approach. Numerous components are made of carbon or billet aluminum, such as the adjustable footpegs and the steering plate with the serial number. The equipment also includes oversized water and oil radiators with WSBK technology, a final drive with a titanium rear sprocket and a lightened front sprocket from PBR, and a 520 Regina Chain.\

LIMITED EDITION
25 of the 30 Aprilia X 250TH units produced will be destined for the U.S. market at an MSRP of USD 150,000, while the remaining 5 will be dedicated to other markets, including Europe, at a price of €115,000 + VAT. Online booking will be possible immediately in the dedicated FACTORYWORKS.APRILIA.COM area (https://factoryworks.aprilia.com/).

In addition to the limited and numbered edition of the Aprilia X 250TH, buyers will also receive a Yashi laptop with the software to manage the ECU parameters and electronic strategies, a mat, a personalized bike cover, RCB titanium front and rear stands, and IRC tire covers.

Aprilia X 250TH falls within the Factory Works program launched by Aprilia Racing: a project conceived and realized within the Noale-based Racing Department intended to make the same technology developed in racing available to those who intend to compete at top levels in factory derivative series, or for those who want to own an RSV4 or Tuono V4 with top tier performance.

MASSIMO RIVOLA, APRILIA RACING CEO:
“Once again, Aprilia Racing introduces an exclusive product which is even closer to a MotoGP bike. The Aprilia X 250TH is clearly an item for true connoisseurs – something unrivaled. Over the years, the X bikes have become highly sought after for both collectors and for those seeking to experience a thrill that is extremely close to what MotoGP riders feel.”

FABIANO STERLACCHINI, APRILIA RACING TECHNICAL DIRECTOR:
“The Aprilia X 250TH is another great Aprilia Racing creation in which, like with the previous editions, we paid painstaking attention to the aspects that set it apart, starting with the highly sophisticated aerodynamics reminiscent of the MotoGP bike concepts, all the way to numerous engine upgrades, with an increase in power compared to the previous ones. The truly particular aspect of this project, however, is the cutting-edge braking system. The carbon discs allow extreme braking without stressing the braking system. This is MotoGP-derived technology, partly utilized in Formula 1 as well, and it represents an entirely new feature that will allow braking performance never before seen on a bike sold to the general public.”
