Product Description
Yamaha Genuine factory starter motor brush kit (BRUSH SET). Manufactured with high-conductivity copper-graphite carbon brushes pre-soldered to the base terminal plate with heavy-duty tension springs, this original internal repair kit restores electrical conductivity and rotational cranking torque to the factory Mitsuba starting motor, resolving slow or dead-crank conditions on Minarelli/Yamaha 50cc 2-stroke scooter engines.

Fitment & Technical Details
Installs directly inside the main starter motor housing. Requires complete removal and disassembly of the starter motor outer casing. It is highly recommended to clean the armature commutator surface with electrical contact cleaner and light emery cloth before installing the new brush assembly to ensure maximum electrical contact and prevent premature brush wear.
