Securing castle nut tool, SIP, Vespa GS 160 / 180 Super Sport

Ø 51,0 mm, 2x9 pins, 3mm/5mm

The SIP castle nut tool is used to open and close the drive shaft castle nuts of vintage Vespa models. In the course of time castle nuts with different notch layouts have been used. For that reason we designed the SIP castle nut tool in a way that it will simultaneously open/close castle nuts with different sets of notches. The tool for the 160 GS/180 SS is thus suitable for castle nuts with a distance of either 3mm or 5mm between their 9 notches. The tool for the 125 VNA/VNB will open and close castle nuts with either 8 or 9 notches. While both ends of the tool are equipped with cogs that will engage in the notches of the castle nut, it is - thanks to a square middle part - easily operated with a standard 1/2" wrench. Attention "left thread", don`t use a wheel gun!
