Front half-pulley -PIAGGIO Ø137mm - 78Z- Piaggio 125-180 cc 2-stroke (78 teeth) (type Runner FX-FXR)

Belt pulley suitable for Piaggio/Gilera 125/180cc 2-stroke engines.
The pulley shown here has 78 teeth and a diameter of 137mm (measured over all, including teeth).

It is therefore suitable for all second-generation engines that already have crankshafts with a Ø92mm cheek diameter. These are:

• GILERA; Runner FX125, FXR180

• PIAGGIO: Skipper 125/150 2-stroke, Hexagon LX125/LXT180, TPH125XR 2-stroke

• ITALJET: Dragster 125/180 2-stroke

NOTE
The first generation of engines still has a pulley with only 76 teeth and Ø135mm (also recognizable by the smaller crankcase diameter with only Ø90mm). The pulley does not fit on these vehicles.
Vehicles for which the pulley does not fit are
PIAGGIO: SKR125/150, TPH125, Hexagon EX125/150

TIP
The pulley for these vehicles is no longer available. In order to be able to continue riding them, the 78T/137mm pulley offered here can be used if the freewheel between the pulley and starter motor is removed at the same time. This is only located in the engine block and can simply be removed. The vehicle can then only be started with the kickstarter.
