MINI-Z BUGGY (MB-010) Pinion & Spur Gear Set - Kyosho MB011  [KY-MB011]

Mini-Z Buggy drivetrain overview

This RC accessory replaces the worn pinion and spur gears in MINI-Z BUGGY drive trains, offering a direct metal spare to restore reliable power transfer. It suits owners maintaining or refreshing MB-010 based Mini-Z buggy models and is useful when changing gear ratios during setup work.

Gears determine acceleration, top speed and motor loading. Swapping pinion and spur combinations changes the effective ratio so you can prioritise low-end punch or higher top speed depending on track demands. This set is made as a modular spare that installs into the stock gearbox layout used on Mini-Z buggy platforms referenced in the product notes.

Installation notes: seat the pinion correctly on the motor shaft and set proper gear mesh to avoid binding or excessive backlash. Check pinion alignment and spur seating, verify bearings and shaft clearances are clean, and recheck mesh after a short break-in run. Use the car's existing fasteners and follow standard Mini-Z maintenance procedures when replacing drivetrain components.
