FROM THE NOALE-BASED RACING DEPARTMENT TO CELEBRATE 250 YEARS
OF THE UNITED STATES OF AMERICA’S DECLARATION OF INDEPENDENCE.
THE FIRST AND ONLY BIKE IN THE WORLD ON THE MARKET WITH CARBON-
CARBON BRAKES, A FEATURE EXCLUSIVE TO MOTOGP, TO CONFIRM THE
DIRECT CONNECTION WITH THE PREMIER MOTORCYCLE RACING
CHAMPIONSHIP.
THE APRILIA X 250TH, WHICH HAS A SPECTACULAR “STARS AND STRIPES”
THEMED LIVERY INSPIRED BY THE AMERICAN FLAG, IS THE MOST
POWERFUL RSV4 EVER BUILT, WITH 240 HP POWERING JUST 165 KG FOR A
WEIGHT/POWER RATIO THAT PROVIDES AN UNPRECEDENTED RIDING
EXPERIENCE.
SIXTH GENERATION OF THE X BRAND, THE NEW APRILIA X 250TH IS AN
AERODYNAMIC EXCELLENCE WITH THE VERY LATEST GENERATION SEAT
WINGS, FOUND ONLY ON THE RS-GP PROTOTYPE THAT RACES IN THE
MOTOGP WORLD CHAMPIONSHIP.
Austin, 27 March 2026 – 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 in the world on the market fitted with carbon-
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 RS-
GP ridden by Marco Bezzecchi and Jorge Martín.
Furthermore, on the aerodynamics front, the latest generation MotoGP-derived seat
wings have been updated. These are elements that confirm the vocation of the “X”
brand in representing the most advanced point ever of 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 340mm high mass,
combined with carbon pads and a billet aluminium calliper with cooling fins. The system
is completed by the rear brake disc, which is gripped by a nickel-plated calliper.
The use of carbon discs translates into half the weight of traditional steel discs,
contributing to improving the bike’s overall handling, whereas the carbon pads mean
about one-third less weight than sintered pads. At the same time, it ensures consistent
performance even in conditions of extreme use, bringing the riding experience and
braking power even closer to those of the 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 starting from the design of the rear, faithfully
replicating the airflow. The aerodynamics package features advanced, MotoGP-
derived solutions which include seat wings – Aprilia Racing 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 placing the
carbon fibres in order to make it 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 feeling between
rear tire performance and the rider’s sensations. Completing the package is the SC
Project titanium MotoGP replica double-exhaust, designed to maximise performance
and give it 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 as great as
the Aprilia RSV4, increasing stability and reducing wheelies, whereas in leans, there
is three times as much load, all to the advantage of grip on 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 1099cc 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
STM dry clutch.
ELECTRONICS
Electronics management is handled by the Aprilia Racing APX control unit, a direct
evolution of the systems used in the WSBK Championship that Max 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 for management of the front lift mitigation feature
and the power, traction control, and engine brake for each individual gear, and it is
completed 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 wheel rims in magnesium, shod with the 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 aluminium such as, for example, the adjustable footpegs or
the steering plate (upper triple clamp) with the serial number. The equipment also includes oversized water and oil radiators with WSBK technology and a final drive that has a titanium rear sprocket and lightened front sprocket made by PBR, as well as a 520 Regina Chain.
LIMITED EDITION
25 of the 30 Aprilia X 250TH units produced will be destined for the U.S. market at
MSRP $150,000 USD, whereas the remaining 5 will be dedicated to other markets,
including Europe, at a price of €115,000 + VAT. Online booking will be possible

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
unrivalled. 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.”
