Precision spacing for motor alignment using Kyosho UM523

The Kyosho UM523 Motor Offset Spacer is made to suit RB5, RT5 and SC chassis and gives repeatable motor positioning for accurate setup work. Adjusting the motor mounting with this spacer helps refine handling traits so the car responds more predictably at race pace.

Major advantages of the UM523 spacer

  • Compatibility: Intended for RB5, RT5 and SC mounting systems.
  • Functionality: Lets you micro-adjust motor location to influence handling balance.
  • Material: Durable manufacturing for regular tuning and track use.
  • Performance: Promotes stable handling and improved corner entry consistency.
Remark :
Due to limited stock availability, please notice that some Kyosho 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.

Does the UM523 require special tools to fit?

No specialist tools are required. Standard hex drivers and a torque driver for final tightening are sufficient for correct installation.

Will the spacer affect driveline angles or bearings?

Minor offset changes are unlikely to affect driveline geometry significantly, but check bearing preload and shaft alignment after fitting to ensure there is no binding.

How should I evaluate handling after fitting the spacer?

Make one change at a time and test on a consistent track section. Note steering entry, mid-corner balance and exit behaviour to determine whether further adjustment is needed.

Is the UM523 suitable for both practice and race settings?

Yes. It is a straightforward tuning part that can be used during practice to refine setup and then carried over to race configuration when you find the preferred position.

Should I check gear mesh after installing the spacer?

Always recheck gear mesh after any motor position change. Small adjustments may require a slight pinion move to maintain correct engagement and avoid premature wear.
