Yokomo RP-057A Racing Performer Rotor #57 M3 D12.5xd7.25 Race Rotor  [RP-057A]

Upgrade path for Yokomo RP-057A Racing motors

The Yokomo RP-057A Racing Performer Rotor #57 M3 D12.5xd7.25 offers a simple route to more immediate throttle response for Racing Performer M3 series motors. It is suited to racers looking to refine motor characteristics without complex mods.

Magnet layout tuned for stronger acceleration

This rotor carries a high-energy magnet that helps deliver stronger launches and improved momentum down the straights. The magnet measures 12.5mm outer diameter and 7.25mm inner diameter, which supports the enhanced acceleration profile.

Reliability during extended runs

Built to hold magnetic strength under heat, this rotor helps maintain consistent lap times during longer sessions. If magnet performance reduces over time, replacing the rotor is the quickest way to return to expected power levels.

Setup pointers for balanced handling

To get the most from the rotor, pair it with a well-calibrated ESC and matching chassis settings so the extra acceleration does not upset cornering balance. Routine motor checks will also preserve performance.

For club and competitive drivers alike, the Yokomo RP-057A Racing Performer rotor gives a reliable boost to throttle response while remaining easy to install and maintain.
