Precision Spur Gear for Circuit Use

The Kyosho UB050-78 spur gear is developed with competitive drivers in mind. Featuring a 48-pitch, 78-tooth specification, this gear is intended for the Ultima RB7.5 range and promotes even power transfer with crisper acceleration. Machined dimensions deliver repeatable fit and predictable drivetrain behaviour when tuning setups.

Tight Tolerances for Reliable Mesh

Specifically suited to the Ultima RB7.5, the Kyosho UB050-78 provides consistent tooth engagement and durable performance. The 48-pitch profile pairs with common pinion gears so you can alter ratios to match motor and track characteristics.

Durability for Frequent Running

Made from robust composite materials, this spur gear reduces wear and helps maintain drivetrain integrity in regular racing. Its construction helps prevent premature tooth wear and keeps handling consistent over time.
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.

Is the Kyosho UB050-78 a direct replacement part?

Yes, this spur is specified for the Ultima RB7.5 and can be used as a replacement when matching pitch and tooth count are required.

How often should I inspect the gear for wear?

Inspect teeth and contact surfaces after every few sessions or if you notice unusual noise or slop. Early replacement prevents damage to pinion or bearings.

Can this spur handle high-power brushless setups?

The composite build is designed for competitive use; however, ensure your motor and gearing choices are matched and monitor for heat and wear in very high power installations.

Any tips for quieter running?

Correct mesh, secure mounting, and checking bearings for smooth rotation are key steps to reduce noise. Minor adjustments to pinion seating can also improve silence.
