Built for the ultra-competitive Stock racing category around the world, the XeRun V10 G4 21.5T motor has been tested and developed intensively by factory drivers including Spencer Rivkin, Jan Ratheisky, and Max Machler to deliver ultimate performance.

The new generation V10 G4 motor features a redesigned stator for higher efficiency, an ultra-high grade custom magnetic ring rotor for maximum torque output, and a 5% increase in output power. Internal resistance is reduced by about 4%, resulting in a more efficient and cooler motor. The fully exposed stator core and maximised outer diameter increase the stator heat dissipation area by 25.6% compared to the V10 G3R motor.

The 13.5T–21.5T motor is equipped as standard with a super magnetic rotor (PN308204445), the most suitable rotor for Blinky Stock racing applications. An optional magnetic rotor (PN 30820416) is better suited for BOOST competition applications. Optional Rotor is available.
