Precision Drivetrain Upgrade for the ULTIMA RB6

The Kyosho UM723 Gear Box Set is intended for the ULTIMA RB6 and enhances mid-motor drivetrain strength. It improves drivetrain feedback and provides a more controlled power flow for tight circuits.

Why the UM723 Stands Out

  • Compatibility: Engineered specifically for the ULTIMA RB6 mid-motor arrangement.
  • Durability: Produced from durable materials to reduce distortion and wear.
  • Precision Fit: Ensures accurate engagement with existing drivetrain parts.
  • Performance Boost: Produces steadier acceleration and cleaner handling under braking.

Practical Advantages for Racers

The Kyosho UM723 is suited to those who demand repeatable lap times and trouble-free drivetrain behaviour. It is a sensible upgrade for maintaining competitive pace and reducing component swap frequency.
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.

Will this gearbox fit without chassis modification?

Yes, the UM723 is designed for direct fitment into the RB6 layout in standard mid-motor installations.

How often should I check the gears?

Inspect gear mesh and bearings after a few sessions and during any signs of noise or slippage to catch wear early.

Can I upgrade bearings when fitting this set?

Upgrading to high-quality bearings is recommended for improved longevity and reduced rolling resistance.
