Durable 72T Spur for Racing

The Kyosho UM730-72C 48P 72T spur gear fits RB7 and RB7SS models and is aimed at drivers who want dependable drivetrain behaviour. It promotes even power flow from the motor to the drivetrain during competitive running.

Performance Highlights

  • Exact Fitment: Manufactured to match the RB7 and RB7SS geometry for straightforward replacement.
  • Long-Lasting Materials: Designed to resist wear under typical race conditions to extend service intervals.
  • Tooth Count Tradeoffs: With 72 teeth the gear balances top end speed and low end torque to suit a range of setups.
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.

What maintenance keeps this spur lasting longer?

Regularly remove debris and check for chipped teeth after hard impacts. Keep the mesh correct and replace the spur if you notice excessive wear or deformation.

Is this spur suited to all track surfaces?

The spur performs well on carpet, dirt and asphalt when paired with the right pinion and motor tune. Surface grip and setup choices will influence how the 72T behaves.

Can I upgrade to a different material later?

If you want different durability or weight, check for compatible aftermarket spurs that use alternative materials, ensuring pitch and bore match the RB7 or RB7SS.
