Vespa PX Rally T5 Sprint BGM PRO Clutch Nut M12 x 1.50

Very high quality special nut, made in germany, for all Vespa engines with the clutch on the crankshaft before year of manufacture 1990 which have a so-called castle nut in the original.

Thus suitable for all vehicles from year of manufacture 1950, such as V1-V5, VNB, VNA, GS150, GS160, Sprint, Rally, GT, GTR, T5, Cosa1, PX, PE etc...

This nut, made in Germany for us, completely replaces the old-fashioned castle nut and thus allows safe and precise work even with a torque wrench. In addition to the precise manufacturing, it is also suitable for a tightening torque of over 70Nm due to the use of a steel of hardness 10. Many castle nuts do not even manage half of this value. This puts a slipping and a defect of the crankshaft / clutch hub by a loosened clutch nut ad acta.


  • Replaces the original clutch crown nut
  • Fits all Largeframe with old 6/7 spring clutch type
  • Hardness: 10
  • Possible tightening torque: more than 70Nm
  • Thread: M12x1,50 (with collar)
  • Diameter at the collar: 18,6mm
  • Height: 9mm
  • Width across flats: 15

Incl. matching serrated lock washer

Conclusion: No more slipping when loosening / tightening the nut and a bombproof fastened clutch.
