Track-Calibrated Spur Gear

The Kyosho UB050-78 spur gear is engineered for dedicated RC racers. With a 48-pitch, 78-tooth layout this part is made for the Ultima RB7.5 series and helps deliver smooth power transfer and improved acceleration. Precision machining ensures correct mesh and consistent engagement, making it a dependable component when refining drivetrain response.

Precision Tooth Engagement

Built specifically for the Ultima RB7.5, the Kyosho UB050-78 offers tight tolerances and reliable service life. The 48-pitch design is compatible with standard pinion gears, giving flexibility for gear ratio changes to suit different track demands.

Durable Construction for Racing

Manufactured from quality composite materials, this spur gear resists wear under heavy loads and reduces slop in the drivetrain. Its robust build extends service intervals and keeps performance consistent during competitive sessions.
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 spur gear fit other Kyosho models?

This spur gear is specified for the Ultima RB7.5 platform; while the 48-pitch may mesh with some other Kyosho units, fitment depends on the chassis layout and mounting spacing.

What pinion sizes work best with this 78T spur?

Pinion choice depends on track and motor. The 48-pitch 78T gives a broad gearing range, so trial with common 48-pitch pinions will help you find the right ratio for speed or acceleration.

How should I maintain the spur gear for long life?

Keep the gear free of debris, check mesh regularly, and replace if you notice excessive wear or tooth chipping. Proper pinion alignment and secure mounting extend service life.
