MRR V5m Modified Class Competition Motor

The New Benchmark for Modified Racing

The MRR-V5m is not just an evolution; it is a dedicated powerhouse specifically engineered for high-RPM modified racing. While it shares the iconic Maclan aesthetic with the V5 series, the V5m features a completely unique internal architecture. From the screw sizes to the sensor unit, every component has been optimized to handle the extreme demands of modified class competition.

Key Features

  • Dedicated Modified Stator: A brand-new stator design engineered specifically for maximum High-RPM power delivery and efficiency.

  • Unique Internal Hardware: Featuring specific sensor units and hardware optimized for modified racing—not shared with the standard V5.

  • Enhanced Cooling: Precision-vented housing designed to maintain performance during grueling main events.

  • Maximum Tuning Versatility: A wide range of motor turns and rotor options to suit any track condition or driving style.

Optional Tuning Rotors

Fine-tune your power delivery with our precision-balanced optional rotors:

  • MCL4501 (12.1mm): Maximum RPM and top-end speed.

  • MCL4502 (12.2mm): Optimized for a balance of RPM and mid-range torque.

  • MCL4503 (12.3mm): Standard balanced power for consistent driveability.

  • MCL4504 (12.5mm): Maximum torque and braking strength for technical tracks.
