Moturo Alternator Set for Yamaha PW 80 PY 80

Moturo Alternator Set for Yamaha PW 80 and PY 80 91-11

The Moturo alternator set for the Yamaha PW 80 and PY 80 (MY 91-11) — a complete charging package including flywheel. Original spare part design, ready for installation.

The alternator generates the power for your child's motorcycle ignition and lighting, while the flywheel provides the crankshaft with the inertia needed for a smooth idle. The stator, rotor, and flywheel fit onto the crankshaft stub using the PW 80's factory mounting pattern. Torque specifications follow the Yamaha PW 80 workshop manual.

The OEM quality matches the original part: same polarity, same coil arrangement, same winding geometry. The PY 80, which features an identical engine block, uses the same set.

Replacement takes about an hour using a hex key set, flywheel puller, and torque wrench.
