Slim design for sharper drivetrain response

Racers and club drivers seeking crisper acceleration will appreciate the XRAY 18T/64 Narrow Pinion Gear. Constructed from aircraft duraluminum, it is 1.5mm narrower and around 25 percent lighter than a typical pinion, helping to cut rotational mass while keeping needed rigidity.

High precision production and surface protection

Manufactured with XRAYs dedicated precision gear machinery, this pinion achieves excellent concentricity and balance. The production routine includes chamfered edges and a protective hardcoat treatment to extend service life under regular use.

Good mesh behaviour and less drive noise

This narrow pinion meshes smoothly with most spur gears and is optimised for XRAY spur gear sets. Owners often report a noticeable drop in throttle on/off chatter, resulting in a calmer and more predictable drive.
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.

Is special hardware needed to fit this pinion?

No special hardware is normally required if your motor shaft and grub screw arrangement match the pinion bore and set screw style. Verify shaft diameter and secure the pinion with the correct screw torque.

Will the reduced mass help battery life?

Lower rotating mass can slightly improve drivetrain efficiency, which may contribute to marginal gains in run time depending on setup and driving conditions.

How should I check gear alignment after fitting?

Set a correct backlash, inspect tooth contact under rotation, and listen for irregular noises. Recheck after a short test run and retighten the pinion set screw if needed.
