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.

How does the UM723 affect handling on bumpy surfaces?

The improved mesh and fit reduce drivetrain feedback, which helps maintain traction over uneven sections.

Can I reuse my existing screws and mounts?

In most cases you can, but inspect fasteners for wear and replace any that are stripped or stretched to ensure a secure fit.

Is this part suitable for regular practice and club racing?

Yes, the UM723 is built for frequent use and will stand up to regular practice when maintained properly.
