Replacement steel pinion for Inferno MP setups

The Kyosho PNGS0821 steel pinion is supplied as a replacement item, listed as 21T/0.8M/?5.0 and intended for installation on Inferno MP Series platforms such as the MP11e. It is designed solely for RC drivetrain use rather than full-size vehicles.

Built as a plain-steel option, the pinion focuses on extended wear life during typical RC operation and consistent tooth engagement for reliable gear contact. The 21-tooth specification and 0.8 module correspond with motor pinion dimensions commonly used in Kyosho MP-series cars; the "?5.0" entry should be regarded as provided information.

Fitment tips: verify pinion bore match and set-screw position before final mesh, ensure correct motor shaft seating and secure the pinion with appropriate hex screw torque, and confirm spur clearance to prevent premature damage. When adjusting gear ratios, note that a different pinion tooth count alters acceleration and top speed, so trial changes incrementally.

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 ?5.0 marking a spec I need to match?

The "?5.0" text appears in the supplied product name; treat it as informational. Confirm the main dimensions you need are the 21T tooth count and the 0.8 module for compatibility.

How do I avoid premature wear after fitting?

Ensure the mesh is not overly tight, secure set screws correctly, and verify spur clearance. Regular inspection after a few runs will catch early issues before they cause damage.

Can I swap this pinion to alter performance?

Yes. Changing to a different tooth count modifies the overall gear ratio and changes acceleration versus top speed. Make small incremental changes and test each setup before extended use.
