The Yokomo RP-119 spare rotor is intended for the Racing Performer DX2 Type-R and comes in a 12.5mm diameter suited to 15.5T motors. Built with durability in mind, the rotor's magnet ring helps absorb impacts and keeps the assembly working reliably lap after lap.
Swapping rotor sizes allows operators to adjust the motor's rotational traits. The RP-119 is ideal for 15.5T tuning, while alternative sizes such as a 12.3mm rotor are commonly chosen for 11.5T or 13.5T setups to alter torque delivery and throttle feel.
