Moturo flywheel for Yamaha PW 50

Moturo Flywheel for Yamaha PW 50

The Moturo flywheel for the Yamaha PW 50 (MY 82-13) — the magnetic rotor on the crankshaft that powers the ignition and alternator. Identical to the original part, ready for installation.

The flywheel sits on the crankshaft stub and works in conjunction with the stator plate. The rotor supplies the ignition coil and alternator via the magnets in the inner ring. The torque for the flywheel nut follows the PW 50 workshop manual.

The geometry and taper are identical to the original PW 50 flywheel (model years 1982 to 2013). The Loncin PY 50 also uses the same flywheel geometry and is a direct fit.

Replacement takes about an hour using a flywheel puller, socket wrench, and torque wrench.
