Moturo rear brake drum suitable for Honda Monkey Z50

Moturo Rear Brake Drum for Honda Monkey Z50

The Moturo rear brake drum for your Honda Monkey Z50 (Z50A, Z50G, Z50J, Z50R, 74-86) — a wear part that develops play and scoring on the running surface after high mileage. 49cc platform, ready to install.

The brake drum sits in the rear wheel hub of the Monkey and houses the brake shoes and the brake cam. The inner diameter and mounting correspond to the OE hole pattern of the Z50, with torque values according to the Monkey workshop manual. This ensures the shoes grip cleanly on the running surface without any play on the shaft.

Replacement takes about an hour using a socket wrench set for the axle nut, a torque wrench, and possibly a rubber mallet for the drum. Check the brake shoes and axle retainers before installation and replace them if necessary.
