Motor summary and setup tips

The Yokomo YOKRPM-B45 is a 4.5T brushless unit intended for racing-grade RC car use. This description focuses on fitment, setup considerations, and tuning influence rather than promotional performance numbers, and treats the motor as a component for scale car models.

Decide compatibility by checking can dimensions, mounting hole layout, pinion bore, and ESC compatibility. Fit the YOKRPM-B45 where the can and screw pattern match your chassis plate and ensure the pinion and shaft sizes are compatible with your gearbox.

Fitting a 4.5T motor such as the YOKRPM-B45 usually leads to tuning priorities around gear ratios, ESC timing, and battery selection to control torque delivery versus peak speed. Fine-tuning gearing and throttle curves is often the most effective way to refine handling without replacing hardware.

Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Which batteries work best with the YOKRPM-B45?

Match battery voltage to your ESC and gearing goals; higher voltage raises top speed but increases current and heat, so choose a pack with suitable discharge rating for your setup.

Will my existing pinion gear fit the motor shaft?

Check the pinion bore against the motor shaft diameter and confirm the key or set screw arrangement matches; if in doubt, measure both parts before ordering.

Can I use this motor in modified touring car gearboxes?

Compatibility depends on can length, mounting pattern, and shaft alignment; confirm those dimensions and ensure adequate cooling and ESC capacity when running in modified gearboxes.

How does changing gearing affect driveability?

Lowering the gear ratio increases acceleration but loads the motor more, while higher ratios improve top speed and reduce load; adjust gradually and monitor motor temperature after each change.
