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

Thus suitable for all vehicles from year of construction 1950, e.g. 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 crown nut and allows a safe and precise work even with torque wrench. In addition to precise manufacturing, it is also suitable for a tightening torque of over 70Nm due to the use of a steel with a hardness of 10. Many crown nuts do not even achieve half of this value. This means that a slipping or defective crankshaft/clutch hub is now a thing of the past due to a loose clutch nut.

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

Incl. The result: No more slipping when loosening/tightening the nut and a bomb-proof coupling.

TIPP:Also suitable as a polar wheel nut for Flytech/Vespatronic polar wheel nut for Vespa GS160 / GS4 (VSB1T), SS180 (VSC1T), Rally180 (VSD1T), Rally200 (VSE1T, Femsatronic)


Fits the following vehicles

Wie immer Top

gute Alternative zur Kronenmutter, Fächerscheibe dazu ist aber unnötig, Nord-Lock ist empfehlenswerter!!

Qualität ok, passte bei mir leider nicht, da die Mutter zu gross war, M10 wäre richtig

passt und erfüllt den zweck, macht spez.-werkzeug für die kupplungsmutter überflüssig und spart zeit beim ein- und ausbau

damit bleibt die Kupplung wo sie hingehört
