Moturo flywheel cooling fan for 47-49cc 2-stroke pocket bike

Moturo Flywheel Magneto for 47-49cc 2-Stroke Pocket Bike

The Moturo magneto with magnet for 47-49cc 2-stroke pocket bikes, dirt bikes, and mini quads — the centrifugal mass and ignition pulse generator on the crankshaft stub. Diameter approx. 100 mm, ready for installation.

The magneto sits on the crankshaft cone and uses its integrated magnet to send the ignition pulse to the pickup coil. The geometry is identical to the original wheel and replaces the installed flywheel without requiring modifications to the shaft, cooling shroud, or ignition base plate.

The cooling fan ring simultaneously supplies the cooling airflow over the cylinder head of your pocket bike or mini quad. Replacement takes about half an hour with a flywheel puller and a socket wrench for the central nut.
