Mini-Z Buggy (MB-010) Pinion & Spur Replacement - Kyosho MB011  [KY-MB011]

Mini-Z Buggy pinion and spur essentials

This metal pinion and spur set replaces the drivetrain gears on MINI-Z BUGGY models, supplying a direct-fit replacement for wear or damage. It is suitable for MB-010 based Mini-Z buggies and for users altering ratios during setup changes.

Gear selection governs acceleration, peak speed and the load on the motor. Altering pinion or spur sizes adjusts the final drive, enabling a compromise between low-speed torque and higher top speed depending on circuit demands. The parts are configured to fit the common gearbox arrangement on Mini-Z buggy platforms detailed in the product text.

Fitting guidance: make sure the pinion sits correctly on the motor shaft and that gear mesh is set to avoid binding or excessive clearance. Inspect alignment and ensure spurs seat evenly in the gearbox, keep bearings and shafts free of contamination, and recheck mesh after a short test run. Reuse the vehicle's original mounting hardware and follow standard Mini-Z maintenance when replacing drivetrain components.
