Maclan Racing proudly presents the MRR V5 Stock Spec Competition Motor Series, their next-generation platform developed under the latest 2025 ROAR rules. Every detail of the V5 has been refined through extensive engineering and race testing to deliver stronger torque, smoother control, and improved efficiency for today's demanding RC racers.
Next-Gen ROAR-Legal Stator Design: Engineered stator geometry built from fresh 2025 ROAR-spec laminations for improved magnetic balance and reduced core loss. The result is crisper throttle response, higher RPM, and superior temperature stability.
Enhanced Cooling and Airflow: A redesigned CNC-machined endbell with high-flow cooling ports reduces operating temperature by up to 25deg F compared with the previous generation.
Performance You Can Feel: From improved low-RPM smoothness to higher efficiency at peak output, the V5 translates every amp into usable traction. Whether you race on-road, off-road, or oval, the difference is immediate.
