Track-focused motor overview

The Yokomo YOKRPM-B45 is a brushless motor rated at 4.5T and intended for racing performance in RC car setups. This description emphasises installation, setup decisions, and tuning effects rather than promotional or unverifiable speed claims. The unit is presented strictly as an RC-scale motor for car models.

Compatibility decisions hinge on the motor can diameter, mounting hole pattern, pinion shaft size, and ESC capabilities. Fit the YOKRPM-B45 where the can and screw layout match your chassis motor plate, and double-check pinion fitment and shaft diameter before purchase.

Tuning a 4.5T like the YOKRPM-B45 typically centres on gear ratio, ESC timing, and battery selection to balance initial acceleration with sustained top speed for your track. Small adjustments to gearing and throttle curves usually deliver the most predictable on-track behaviour without hardware modification.

Specifications

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.

Will the YOKRPM-B45 physically fit my motor mount?

Measure your motor can diameter and the mounting hole pattern on the chassis motor plate, confirm screw spacing and shaft diameter, then compare to the YOKRPM-B45 before buying.

How should I check pinion compatibility?

Verify the pinion bore matches your motor shaft diameter and ensure the chosen pinion clears surrounding hardware; trial-fit a spare pinion to avoid last-minute issues.

Do I need a sensorless-capable ESC?

Yes, confirm your ESC supports sensorless brushless motors and the battery voltage range you plan to run; check ESC presets for 4.5T class motors as a starting point.

Any quick tips for first installation?

Secure the motor with correct screws, align the pinion and spur gear for minimal mesh play, and run a short test at low throttle while monitoring temperature and ESC behavior.
