Extra hard clutch nut, made in germany, for use with very heavily loaded drives e.g. in racing. Can of course also be used as a high quality replacement for the original nut on a standard engine.
This very high quality special nut is suitable for all Vespa engines with a clutch on the auxiliary shaft (Smallframe: V50, PV, ET3, PK, PK XL, PK XL2). Manufactured in Germany for us, it is, in addition to the precise manufacturing, by using a steel of hardness 10, also suitable for a tightening torque of over 70Nm. Many standard nuts do not even achieve half this value. This means that slipping and a defective crankshaft/clutch hub due to a loose clutch nut is no longer an issue.

• Replaces the original clutch nut
• Fits all small frame motors
• Hardness: 10
• Possible tightening torque: more than 70Nm
• Thread: M10x1.50 (with collar)
• Height: 9mm
• Width across flats: 16
