GY6 Drum Brake Rear Axle (Output / Final Shaft)

GY6 Rear Axle for 125cc - 150cc Drum Brake Engines

This output shaft, commonly called the rear axle, is built for GY6 engines between 125cc and 150cc. It suits models that use drum brakes. The part carries power from the engine through to the rear wheel. As one of the core GY6 scooter parts, it plays a big role in keeping the scooter running smoothly and dependably.

Construction and Design

Overall length is 133mm, so the axle is sized for a range of GY6 models. The smooth section measures 17mm across, and the bearing section measures 27mm across. The axle has 19 splines and comes with a circlip to hold it in place. Measure and inspect your existing axle before ordering to be sure you pick the right one for your scooter.

When to Replace Your Rear Axle

Swap out the rear axle if you notice uneven wear, strange noises, or a drop in performance. Checking it regularly can catch problems early, before they turn into bigger failures. If you are servicing or repairing a GY6 scooter, this is a part worth looking at closely.
