Maclan MRR V5 Competition Sensored Stock Class Brushless Motor (21.5T)

The Maclan MRR V5 Competition Sensored Stock Class Brushless Motor is a 21.5T motor designed around the updated 2025 ROAR rules. Its next-generation stator, reduced internal resistance, and enhanced sensor placement support crisp throttle response, efficient power delivery, and consistent control.

High-flow cooling ports help lower temperatures by up to 25°F, while the lighter overall design improves balance and responsiveness. The motor includes Maclan’s High Torque Rotor for strong, usable power and is designed and engineered in the United States.
