Track-focused performance from the XRAY 25T pinion

The XRAY 305925 Narrow Pinion Gear delivers a lightweight, accurate gearing option for club and track racers. Made from aircraft-grade duraluminum, this pinion is 1.5mm narrower and about 25% lighter than conventional pinions to reduce rotating mass and improve throttle response.

Precision machining and durable finishing

Produced on a specially modified precision gear machine, the XRAY 25T pinion maintains very tight tolerances for excellent concentricity. Each tooth and edge is chamfered, then the gear receives a run-in treatment and a hardcoat finish to boost wear resistance without adding excess weight.

Quiet, compatible gearing solution

Designed to mesh smoothly with spur gears, including XRAY spurs, this pinion reduces throttle on/off noise and delivers consistent engagement. It is a straightforward upgrade for racers seeking cleaner gear operation or lighter drivetrain components.
Remark :
Due to limited stock availability, please notice that some XRAY 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.

What is the exact material used for the XRAY 305925 pinion?

The gear is machined from lightweight aircraft-grade duraluminum, chosen to combine strength with reduced weight for better acceleration and handling.

Will this 25T pinion fit non-XRAY spurs?

Yes. The pinion is cut to standard tooth profiles and is compatible with most spur gears, offering smooth meshing across different brands.

Does the hard coat affect gear break-in?

The hardcoat improves surface durability; a short run-in still helps seating and reduces initial noise, as the manufacturer recommends.
