Race-Oriented Spur Gear

The Kyosho UB050-78 spur gear is made for competitive RC use. With its 48-pitch and 78-tooth profile, this component fits the Ultima RB7.5 series and helps provide even power transfer and improved throttle response. Tight tolerances ensure dependable engagement and consistent behaviour when you change ratios for different track conditions.

Designed for Accurate Mesh

Matched to the Ultima RB7.5 chassis, the Kyosho UB050-78 combines precision and toughness. The 48-pitch format is compatible with common pinion gears, so you can experiment with different pinion sizes to find the best setup for speed or acceleration.

Stands Up to Competitive Use

Constructed from quality composite material, this spur gear is built to reduce wear and maintain stable performance under load. Its sturdy design helps limit drivetrain play and prolong service life during frequent racing.
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 do I check spur to pinion mesh correctly?

Set the pinion on the motor shaft, bring the spur into mesh, then use a thin shim or paper to set a small clearance. Spin the drivetrain to confirm smooth engagement without binding.

Will this gear affect top speed or acceleration?

Gear size influences final ratio. The 78T spur gives a base for higher top speed with larger pinions or stronger acceleration with smaller ones. Choose pinion sizes to tune the balance you need.

Is any special tool needed to fit the Kyosho UB050-78?

Standard RC tools are sufficient: hex drivers for motor mount and pinion set screw, plus a wrench for the spur gear hub if applicable. Ensure screws are torqued to manufacturer recommendations.
