After countless hours of testing, development, and refinement, we are proud to introduce the XB-SF.
Our goal was clear: achieve the target weight while maintaining the perfect amount of chassis flex. Every component was carefully designed, tested, reviewed, and refined until we achieved the balance we were looking for.
The XB-SF combines innovative engineering with proven XBility performance:
• Carbon fiber chassis with strategically placed brass weights, achieving the target weight while delivering the ideal weight distribution and the perfect balance between rigidity and chassis flex.
• A completely redesigned tweak plate, with optimized spring mounting points that allow the springs to work more effectively, delivering increased precision, improved rear-end rotation, and a more consistent feel on the track.
• Knuckles with internal O-rings, transforming the kingpin damping system into true miniature shock absorbers for smoother, more controlled, and more consistent front suspension movement.
• Floating servo mount, minimizing interference with chassis flex and allowing the chassis to work exactly as intended.
• Completely redesigned motor pod, lowering the motor’s center of gravity, while a brass pod on the opposite side provides the desired left-to-right weight balance.
• Our proven 3-point ball differential, engineered to virtually eliminate wheel play while delivering exceptionally smooth operation, more efficient power transfer, and outstanding consistency.
The result is a car that achieves the target weight, delivers the ideal amount of chassis flex, and provides a balanced, precise, and confidence-inspiring driving experience.
The XB-SF is built for racers who want maximum performance in a simple, efficient package.
The XB-SF is now available for pre-order.
