Kyosho MB011 - Pinion & Spur Gear Set for MINI-Z BUGGY  [KY-MB011]

Mini-Z Buggy pinion and spur overview

This RC-scale accessory replaces the pinion and spur gears used on MINI-Z BUGGY setups, giving a direct-replacement option when wear or damage affects drivetrain performance. The set is intended for owners maintaining MB-010 based Mini-Z buggy models and for those who need to change gear ratios as part of tuning setups.

Gears play a central role in acceleration, top speed and motor load. Swapping pinion and spur combinations alters the effective gear ratio, allowing a quick trade-off between low-end punch and higher top speed during on-track tuning. This set is presented as a modular spare set that fits into the existing gearbox arrangement of Mini-Z buggy platforms specified in the product information.

Installation notes: ensure correct pinion seating on the motor shaft and set the gear mesh to avoid binding or excessive play. Inspect pinion alignment and spur seating in the gearbox, confirm bearings and shaft clearances are free of debris, and recheck mesh after a short break-in run. Use the car's existing mounting hardware and follow standard Mini-Z maintenance checks when replacing drivetrain components.
