Tuning-Focused 48-Pitch Pinion Specifications

The Yokomo YOKPG4825 serves as a 48-pitch pinion designed for hobbyists who make regular gearing adjustments. Its 25-tooth count and ultra-hard designation help maintain consistent engagement and resist wear when you swap ratios to tune performance.

As the gear that sets motor-to-spur ratio, this pinion has a direct impact on acceleration characteristics and peak speed along with motor loading. Proper installation means achieving the correct mesh and securing the motor while maintaining that position to avoid premature tooth wear.

When planning gear changes, rely on the YOKPG4825 for a dependable 25T option that supports fine-grained ratio steps. Pair with matching spur gears, check for burrs after initial runs, and perform light maintenance to keep the gearset running smoothly.
Remark :
Due to limited stock availability, please notice that some Yokomo 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 does switching to a 25T pinion affect performance?

Moving to a 25T pinion typically raises effective gearing versus a lower-tooth pinion, which can alter acceleration and top speed depending on the spur gear used.

Best practice for setting mesh during tuning swaps?

Fit the pinion, set a minimal running clearance, rotate the drivetrain to verify smooth engagement, then secure the motor while preserving that mesh dimension.

Which spur gear pairing is recommended for fine ratio steps?

Choose spurs with one or two-tooth differences to achieve incremental changes; match tooth profile and pitch to maintain good mesh and efficient power transfer.
