800 gram lightweight aluminum pole wheel suitable for Piaggio Ciao (P, SC, PX, C24), SI, Bravo, Grillo and Boxer with E-ignition (electronic ignition) / ELO ignition and rotary valve crankshaft.
Manufactured by GPO with a cleanly milled spline, precisely fitting cone and high-quality, precise casting. It enables noticeably better acceleration values compared to the standard 1300 g flywheel.
Features:
Internal flywheel diameter: 106mm Outer flywheel diameter: 139.5mm Thread: MF17x1 (fine thread) Direction of rotation: right
OEM no. for comparison purposes: 2238183 / 181103
Note on balancing:
The fan wheel is individually matched to the original rotary valve crankshaft and balanced vibration-free in conjunction with it. Although it does not run exactly smoothly on its own, the interaction with the crankshaft results in a perfectly balanced unit.
Not compatible with full cheek crankshafts.
