Track-Ready Spur Gear from Kyosho

For competitive racers the Kyosho UM730-72C 48P 72T spur gear is made to mate cleanly with RB7 and RB7SS drivetrains. It helps keep power delivery smooth and predictable so you can focus on dialing in suspension and traction.

Why Choose This 48P 72T Spur Gear

  • Precision Engineering: Machined to Kyosho tolerances to ensure correct tooth engagement with RB7 and RB7SS components.
  • Durable Construction: Manufactured from robust material to withstand repeated race use and limit premature wear.
  • Optimized Tooth Count: The 72-tooth layout provides a compromise between speed and torque that suits many race tunes.
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.

Can I fit this spur to other Kyosho cars?

This part is intended for RB7 and RB7SS use. Other Kyosho models may have different pitch, bore, or mounting details so check dimensions before fitting.

Will I need to change my pinion when installing this spur?

Changing the pinion alters final drive ratio. Many racers experiment with pinion sizes after swapping spurs to fine tune acceleration and top speed.

How should I set the gear mesh for best life and performance?

Set a slight clearance so teeth run without binding but without excessive slack. Check mesh under load and inspect for wear after a few runs to confirm correct spacing.
