Crankshaft -BGM PRO (direct intake) 57mm stroke- Motovespa GT 160 (09C) Engine (M09)
Part no.:
BGM057MV
Description
Crankshaft BGM PRO Touring for Motovespa GT160 (C09/M09)
High quality forged crankshaft from BGM PRO for the big Motovespa engines with 160cc. These engines use a mirror symmetrical crankshaft from the factory. So the same type of cone is used on both sides (alternator and clutch side are designed identically).
COUPLING VARIANT
BGM PRO has directly taken the opportunity in the design of the crankshaft and manufactured two versions of the long unavailable GT160 crankshaft.
Motovespa clutch type (same as original Motovespa)
Clutch type PX (fits with PX type clutches)
If you want to build a completely original engine, use the crankshaft for the Motovespa clutch type.
Who wants to use other clutch types than the original GT160 takes the crankshaft for the PX-type clutch type. This allows you to use all clutches that can be used in the PX engines without any further modifications.
MATERIAL
The Motovespa GT160 (actually 160 GT) crankshaft is made from high quality forged blanks. The forged material is much denser and more resistant to bending, making it perfect for use as a durable and strong crankshaft.
BEARING
The lower connecting rod bearing is lubricated via two large lubrication slots and a total of four additional pockets on the side. The SSC racing bearing and the thrust washers on the sides provide a solid bearing. The upper connecting rod bearing is lubricated via two lubrication holes. The INA piston pin bearing is included with the crankshaft.
CONCLUSION
The bottom line is that the bgm PRO crankshaft offers the highest quality in every component. Precision manufacturing, the materials used and, above all, the precise balancing leave nothing to be desired. This guarantees extremely smooth and vibration-free engine running.
