XRay X4F 25

The XRay X4F 25 (XR300204) delivers an all-new 2025 specification focused on traction, rotation and cornering speed. A redesigned chassis, updated steering architecture and revised rear bulkheads shift mass forward while reducing overall weight for a more responsive, planted feel across changing grip levels.

The reworked layout moves key components forward and narrows the chassis to enhance flex characteristics. Together with new tuning weight options and expanded ARS link geometry, the X4F’25 offers broader weight distribution set-up scope for precise steering response and balance.

Key 2025 Chassis Updates

• All-new chassis redesigned to work with new bulkheads and lower arms.
• Motor mount location moved 5mm forward for improved traction.
• Narrowed 5mm at the front and 10mm at the rear to refine flex and reduce chassis drag for greater cornering speed.
• Integrates with the new one-piece aluminium servo/steering mount and battery holder systems.

One-Piece Servo Mount & Steering

• All-new one-piece servo mount moves the servo 5mm forward for more traction.
• Single steering arm mount reduces weight.
• Works with the new battery holder system to position the battery further forward for maximum traction.
• One-piece design eliminates servo movement in hard crashes.
• Ultra-low profile design reduces weight and lowers the CG as much as possible.
• All-new steering arm geometry creates clearance to move the motor and servo 5mm forward, improving in-corner steering.

Weight Saving & Distribution

• X4F’25 is 25g lighter than X4F’24, with strategic lightening of the rear suspension to move weight bias further forward.
• All electronics moved 5mm forward for maximum front traction.
• Greater weight distribution set-up options to adapt to different track conditions.

Rear Bulkheads & ARS Adjustability

• All-new rear bulkheads contribute to additional weight savings.
• Higher ARS link mounting position offers greater adjustment possibilities.
• Allows ARS link mounting more forward or backward, significantly affecting the car’s rotation.

Tuning Weights

• 100g front bumper weight improves traction in lower-grip conditions.
• For high-traction tracks, optional 50g weights can be placed under the front drivetrain.

Together, these updates make the XRay X4F 25 a highly refined 2025 chassis with enhanced forward weight bias, improved steering precision and versatile tuning potential.
