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

Direct-fit rotor upgrade for Yokomo RP-057A motors

This optional rotor for the Yokomo RP-057A Racing Performer Rotor #57 M3 D12.5xd7.25 is aimed at racers who want more aggressive throttle response without complex modification. It matches the Racing Performer M3 motor family.

Compact magnet tailored for speed

The rotor includes a strong magnet sized at 12.5mm outer diameter and 7.25mm inner diameter, contributing to faster off-the-line acceleration and improved mid to top speed behaviour.

Consistent output under stress

Specifications and materials help the rotor retain magnetic strength at higher operating temperatures, which keeps your motor delivering steady performance during extended runs. A rotor swap is the simplest way to recover lost magnet strength.

Practical tuning and maintenance notes

Combine this rotor with reliable ESC settings and a tuned chassis to make the most of the added acceleration. Regular checks of bearings, endplay and motor cooling will keep performance consistent.

From practice sessions to race day, the Yokomo RP-057A Racing Performer rotor is a straightforward upgrade for riders seeking sharper acceleration and reliable top speed.
