BGM Pro Spezial crankshaft with the hub and connecting rod of the 50ccm models (43mm / 87mm) combined with the large alternator stump (Ø24 / 25mm) of the PK125 ETS models. The most stable 50cc crankshaft on the market, fits into every smallframe housing with the appropriate bearing: V50, PK S, PK XL, PK XL2! For conversion bearings see accessories. Suitable for the following engines in order to be able to use cylinders for V50 / PK50 (50-112ccm): Engine housing LML SE125 (as replacement for PK50XL2) Motovespa PK75 XL (96M / 104M) and PK75 FL (127M / 128M) Vespa PK125 ETS engines in general all Vespa Smallframe V50, PV125, ET3 engines if they are equipped with a conversion bearing (25x47x12mm) for the alternator side. VESPA PK50 XL2 The BGM Pro crankshaft uses the large butt of the ETS models with Ø24 / 25mm to be able to use the LML SE125 motor housing we offer with the small cylinders of the 50ccm class. So it is now possible to use the LML SE125 engine case as a replacement for a defective Vespa PK50XL2 engine case. MOTOVESPA PK75 XL / FL The motors of the Motovespa PK75XL and FL models have a cylinder with a Ø47mm bore and 43mm stroke ex works. As a special feature, Motovespa uses a long connecting rod with 97mm with a 15mm piston pin (like the 125cc models in the original). This means that none of the commercially available tuning cylinders can be used on these engines. The stroke is too small for 125ccm cylinders, the connecting rod is too long for cylinders of the 50ccm class.
